Abstract
Description
Technical Field
[0001] This invention relates to the field of electromagnetic relay technology, and more particularly to a combined electrical quantum current transformer. Background Technology
[0002] Currently, with the rapid development of smart grids and new energy power generation, power systems are placing higher demands on the accuracy, stability, and anti-interference capabilities of current measurement equipment. Traditional electromagnetic current transformers are limited by issues such as core saturation and narrow bandwidth, making it difficult to meet the needs of ultra-high voltage, DC transmission, and harmonic detection scenarios. Quantum measurement technology, due to its ultra-high precision and anti-electromagnetic interference characteristics, has become a new direction for breaking through the bottlenecks of traditional technologies. However, existing quantum current transformers are mostly limited to laboratory environments, facing challenges such as large size, high cost, and difficulty in integration with existing combined electrical equipment (such as GIS switchgear).
[0003] Current technologies commonly employ: optical current transformers, based on the Faraday magneto-optical effect, which infer current values by measuring the deflection angle of polarized light. Their advantages include good insulation performance, but they are susceptible to temperature drift and mechanical vibration, resulting in insufficient long-term stability. Rogowski coils, with their coreless structure, are suitable for high-frequency current measurement, but their output signal is weak, requiring external integrating circuits, and their signal-to-noise ratio significantly decreases in complex electromagnetic environments. Superconducting quantum interference devices (SQIs) utilize the superconducting Josephson effect to achieve extremely high sensitivity, but require a cryogenic liquid helium environment, resulting in high maintenance costs and inability to be directly adapted to high-voltage power equipment. Traditional current transformers (CTs) in integrated electrical systems typically employ electromagnetic induction principles, have a compact structure but limited measurement range, and are prone to saturation under fault currents, leading to malfunctions of protective relays.
[0004] Existing technologies suffer from a trade-off between accuracy and dynamic range. Traditional electromagnetic current transformers lack resolution at low currents and are prone to saturation at high currents; while optical solutions offer high accuracy, their dynamic range is limited. Environmental adaptability is poor; quantum measurement devices rely on extreme conditions, while optical components are sensitive to temperature and mechanical stress, making long-term stable operation outdoors or under complex conditions difficult. Integration is challenging; existing quantum sensors are bulky and cannot be directly embedded in the compact space of combined electrical appliances, leading to a surge in installation and maintenance costs. Economic viability is also insufficient; superconducting or precision optical systems are expensive and require regular calibration, hindering their large-scale application in power systems. Summary of the Invention
[0005] This invention provides a quantum current transformer for combined electrical appliances, which addresses the inherent contradiction between high-voltage power equipment and quantum precision measurement. It solves the problems of quantum state instability caused by high-voltage mechanical deformation, difficulty in signal extraction under strong electromagnetic interference, and physical compatibility issues between quantum sensing systems and combined electrical appliances in the prior art.
[0006] According to a first aspect of the present invention, a combined electrical quantum current transformer is provided, comprising: An adaptive packaging system is used to implant NV color center arrays into ion-etched corrugated diamond substrates, with trench depths matching the thermal expansion coefficient of the combined electrical appliance insulation cylinder; the corrugated diamond substrate generates micro-deformation compensation stress under high pressure environment to counteract the interference of insulation cylinder deformation on the color center energy levels.
[0007] A corrugated diamond substrate is bonded to a magnesium fluoride waveguide layer: the refractive index of the waveguide layer is matched to the emission wavelength of the NV color center, a helium ion beam is injected into the bonding interface to form an optical tunneling channel, and a borosilicate glass stress buffer shell is wrapped around the outer layer to output a deformation-resistant quantum sensor head.
[0008] A rotating magnetic field decoupling probe system is used to deploy a triaxial ferrite grid array around the anti-deformation quantum sensing head. The grid spacing is less than 1 / 20 of the power frequency wavelength of the combined electrical appliance. The triaxial ferrite grid array captures the eddy current interference field to generate a magnetic field distribution cloud map. The magnetic field distribution cloud map is input into a microwave phase modulator to extract the gradient vector of the interference field and generate a counter-rotating compensation microwave pulse group. The pulse group is synchronized with the NV color center energy level transition and triggers the quantum state deentanglement effect.
[0009] The current reconstruction engine system is used to input the fluorescence attenuation spectrum collected through the optical tunneling channel and the residual resonant component of the compensated microwave pulse into a dual-channel correlation filter. The Zeeman splitting frequency shift is extracted from the fluorescence attenuation spectrum, the intrinsic magnetic field strength of the resonant component is analyzed, and a frequency shift-field strength nonlinear mapping table is established.
[0010] Compared with existing technologies, the advantages and positive effects of this invention are: This invention achieves environmental interference suppression. The micro-deformation compensation mechanism of the corrugated diamond substrate and the optical tunneling channel of the magnesium fluoride waveguide layer work together to solve the problem of NV color center energy level drift caused by the deformation of the high-voltage insulating cylinder, ensuring the signal stability of the quantum sensing head under mechanical stress. The triaxial ferrite grid array actively cancels power frequency electromagnetic interference by capturing eddy current interference fields and generating reverse compensation microwave pulse groups, avoiding the volume and weight costs of traditional shielding methods. High-fidelity quantum state transmission: The optical tunneling channel formed by helium ion beam injection optimizes the fluorescence collection efficiency of NV color centers, and the borosilicate glass buffer shell further isolates the disturbance of waveguide refractive index by external stress, ensuring the signal-to-noise ratio of the fluorescence attenuation spectrum. Dynamic magnetic field decoupling and reconstruction: The rotating magnetic field decoupling system generates compensation microwave pulses in real time through the interference field gradient vector, triggering quantum state deentanglement to eliminate the cross magnetic field coupling effect. The current reconstruction engine uses a dual-channel correlation filter to synchronously analyze the Zeeman frequency shift and intrinsic magnetic field strength, and directly outputs the current value through a nonlinear mapping table, avoiding the problem of integral error accumulation in traditional current transformers. System-level integration adaptability and adaptive packaging design allow the quantum sensor head to be directly embedded in the insulating cylinder of the combined electrical appliance. The thermal expansion matching characteristics of the corrugated structure avoid packaging failure caused by temperature cycling, meeting the compact installation requirements of GIS equipment.

Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0015] Figure 1 A block diagram of a combined electrical quantum current transformer according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the combined electrical appliance quantum current transformer 100 includes: The adaptive packaging system 101 is used to implant the NV color center array into an ion-etched corrugated diamond substrate, the trench depth of which matches the thermal expansion coefficient of the combined electrical appliance insulation cylinder; the corrugated diamond substrate generates micro-deformation compensation stress under high pressure environment to counteract the interference of insulation cylinder deformation on the color center energy level.
[0016] A corrugated diamond substrate is bonded to a magnesium fluoride waveguide layer: the refractive index of the waveguide layer is matched to the emission wavelength of the NV color center, a helium ion beam is injected into the bonding interface to form an optical tunneling channel, and a borosilicate glass stress buffer shell is wrapped around the outer layer to output a deformation-resistant quantum sensor head.
[0017] Optionally, in some embodiments, the adaptive packaging system 101 specifically includes: The waveguide layer optical adapter subsystem is used to perform refractive index gradient etching on the magnesium fluoride waveguide layer, so that its surface refractive index gradually changes from 2.38 to the diamond refractive index of 2.42; the etching depth matches 1 / 4 optical path difference of the emission wavelength (637nm) of the NV color center to generate a gradient refractive interface.
[0018] The ion beam bonding channel subsystem is used to perform helium ion beam scanning implantation on the surface of a graded refractive interface. The ion energy is controlled at 50keV to achieve an implantation depth of 200nm. The beam current density gradient distribution is positively correlated with the depth of the corrugated trench, forming a spiral lattice defect channel in the interface layer.
[0019] The stress buffer encapsulation subsystem is used to pressurize the borosilicate glass melt to 10 MPa in a nitrogen environment, so that it penetrates and encapsulates the bond body; when the melt cools, it generates directional compressive stress, the stress vector direction of which is orthogonal to the trench extension direction of the corrugated diamond substrate, forming a prestressed buffer shell.
[0020] The sensor head functional integration subsystem is used to synergistically combine the optical properties of the gradient refractive interface, the light guiding capability of the helical lattice channel, and the mechanical protection of the prestressed buffer shell: the waveguide layer achieves zero-reflection photon collection, the ion beam channel establishes a low-loss light transmission path, the buffer shell offsets 90% of the external deformation stress, and the output is a deformation-resistant quantum sensor head with high-pressure immunity characteristics.
[0021] This embodiment breaks through the limitations of traditional packaging technology: the refractive index gradient eliminates the reflection loss at the diamond-magnesium fluoride interface, the spiral lattice defect enables photon directional tunneling, and the orthogonal prestress counteracts the deformation stress of the combined electrical appliance.
[0022] Optionally, in some embodiments, the ion beam bonding channel subsystem specifically includes: A beam distribution modulation component is used to input the trench depth distribution of a corrugated diamond substrate into an ion beam current density modulator: the trench peak region corresponds to a high beam current density region, the trench trough region corresponds to a low beam current density region, the trench slope is mapped to the beam gradient change rate, and a spatially modulated helium ion beam is generated, the density gradient of which matches the trench topology.
[0023] Lattice defect self-organizing components are used to trigger lattice relaxation effects when spatially modulated beams bombard gradient refractive interfaces: lattice vacancy clusters are generated in the high-density beam region, and lattice distortion bands are formed in the low-density beam region. The beam gradient direction guides the vacancy clusters to migrate along isodense lines and spontaneously assemble into helical vacancy chains.
[0024] The channel function solidification component is used to cause a topological locking transformation of helical vacancy chains during annealing: silicon nitride bridges are formed between vacancy chain segments, the distortion band recrystallizes into oriented silicon carbide grains, magnesium atoms precipitated from the interface magnesium fluoride fill the inter-chain gaps, and a helical lattice photon tunneling channel is output, with a channel wall refractive index of 2.0 and an optical transmission loss of less than 0.3dB.
[0025] This embodiment establishes a directional transformation path for mechanical morphology (grooves), beam distribution, and lattice defects, enabling physical coupling between the photonic channel structure and the stress-adaptive characteristics of the corrugated substrate.
[0026] The rotating magnetic field decoupling probe system 102 is used to deploy a triaxial ferrite grid array around the anti-deformation quantum sensing head. The grid spacing is less than 1 / 20 of the power frequency wavelength of the combined electrical appliance. The triaxial ferrite grid array captures the eddy current interference field to generate a magnetic field distribution cloud map. The magnetic field distribution cloud map is input into a microwave phase modulator to extract the gradient vector of the interference field and generate a counter-rotating compensation microwave pulse group. The pulse group is synchronized with the NV color center energy level transition and triggers the quantum state deentanglement effect.
[0027] Optionally, in some embodiments, the rotating magnetic field decoupling probe system 102 specifically includes: The gradient field feature extraction subsystem is used to input the magnetic field distribution cloud map into the eddy current topology resolver, identify the core position of the magnetic field vortex in the field distribution cloud map, calculate the angle between the magnetic field vectors of adjacent grids, extract the direction of maximum gradient change, and generate a three-dimensional interference field gradient vector whose magnitude is proportional to the eddy current intensity.
[0028] The microwave pulse synthesis subsystem is used for a three-dimensional gradient vector input rotating phase synthesizer. The vector direction is mapped to the microwave polarization plane rotation axis, the vector magnitude is converted into the microwave frequency modulation depth, and the vortex core coordinates determine the pulse group time delay output of the reverse rotating microwave pulse group. Its rotation angular velocity is equal to the rate of change of the interference field.
[0029] The quantum state synchronization decoupling subsystem is used for the transmission of reverse-rotating pulse groups through an energy level-locked resonant cavity. The eigenfrequency of the resonant cavity matches the ground-excited state transition energy of the NV color center. The pulse time delay compensates for the optical transmission delay. The microwave polarization plane remains orthogonal to the gradient of the interfering magnetic field, triggering the quantum energy level decorrelation effect. The quantum entanglement between the interfering field and the measurement field is destroyed, and the spin state of the NV color center only responds to the magnetic field of the target conductor.
[0030] The quantum state synchronization decoupling subsystem specifically includes: The energy level matching reference establishment component is used to extract the 2.87GHz characteristic frequency corresponding to the energy gap from the ground state-excited state bandgap value of the NV color center, finely adjust it by ±0.5% according to the stress coefficient of the diamond substrate, lock the lattice resonance mode of the cavity silver coating, and generate a resonant cavity with precise energy level matching.
[0031] The spatiotemporal delay compensation component is used to obtain the transmission delay of fluorescence from the NV color center to the detector based on the optical transmission delay data, and to shift the overall delay value of the reverse-rotated pulse group so that the pulse leading edge is aligned with the fluorescence arrival time to form a spatiotemporally synchronized microwave pulse.
[0032] The polarization orthogonalization control component is used to decompose the direction of the interference magnetic field gradient into three-dimensional spatial angles, rotate the principal axes of the sapphire microwave conductor so that the output microwave polarization plane forms a 90° angle with the interference field gradient, and establish a constant orthogonal polarization state.
[0033] The quantum decorrelation triggering component is used to excite the spin resonance of electrons in the NV color center when the spatiotemporal synchronization pulse carries orthogonal polarization states through the resonant cavity. The orthogonal polarization destroys the quantum correlation phase of the interference field, and the synchronization pulse cancels the energy exchange of entangled states, outputting a pure target magnetic field response signal.
[0034] The quantum deassociation triggering components specifically include: When a spin resonant exciton component is used to transmit spatiotemporally synchronized microwave pulses in a resonant cavity for energy level matching, the silver-plated lattice resonant mode of the resonant cavity focuses microwave energy at a frequency of 2.87 GHz. The pulse width is compressed to 1 / 10 of the spin relaxation time of the NV color center. The peak field strength of the pulse reaches the critical resonance threshold, triggering a directional spin state flip, which only acts on the Zeeman splitting energy level induced by the target magnetic field.
[0035] The associated phase disruption sub-component is used to apply a constant orthogonal polarization state to the gradient direction of the interfering magnetic field. The microwave electric vector and the interfering magnetic field vector form a 90° spatial angle. The quantum fluctuation component of the interfering field is attenuated by the polarization filter, and the target magnetic field induced component passes through the polarization selection window to generate a phase decoupled quantum state.
[0036] The energy exchange blocking sub-component is used to align the leading edge of the spatiotemporal synchronization pulse with the arrival time of the fluorescence. The rising edge of the pulse covers the time window of the entangled state, and the pulse energy absorbs the quantum correlation energy of the interference field. The target spin state evolves in the interference-free bandgap and outputs a pure Zeeman splitting signal with its linewidth compressed to 1% of the original value.
[0037] In this embodiment of the invention, the spin resonance exciter assembly specifically includes: The resonant mode energy focusing module is used to generate standing wave energy focusing effect at 2.87GHz for the resonant mode of the silver-plated lattice. The crystal orientation of the silver lattice is aligned with the microwave electric field vector, and the grain boundary defects form a subwavelength resonant cavity. Surface plasmons enhance the local field strength.
[0038] The pulse spatiotemporal compression module is used to generate nonlinear field strength gain when the spatiotemporal synchronous microwave pulse passes through the energy convergence region. The pulse width is compressed to 5ns, the spin relaxation time is 1 / 10, the pulse leading edge slope increases sharply to 100V / ns, and the peak field strength exceeds the critical threshold of 10mT, generating a supercritical narrow pulse.
[0039] The Zeeman level selective excitation module is used when a supercritical narrow pulse is applied to the NV color center. The pulse spectrum width covers the Zeeman split interval, the peak field strength saturates the non-target energy level transition, the steep leading edge synchronizes the spin precession of all color centers, and triggers the directional flip of the target Zeeman energy level. Its selectivity ratio reaches 1000:1.
[0040] The Zeeman level selective excitation module specifically includes: The leading-edge phase-locking submodule is used for the steep leading edge of supercritical narrow pulses. It extracts the second derivative in the time domain of the pulse rising edge, generates a precession trigger field synchronized with the peak value of the derivative, and phase-locks the initial state of the electron spin of all NV color centers, establishing global spin zero alignment.
[0041] The Zeeman level resonator module is used to determine the difference between the local spin zero and the target Zeeman level. The target level difference is converted into the Larmor precession frequency. Non-target levels are suppressed by the accumulator due to detuning. The precession trigger field initializes the synchronous precession trajectory, forming a level-selective precession loop.
[0042] The directional flip execution submodule is used to select the energy level precession ring during the supercritical narrow pulse duration, maintain the precession cone angle expansion with the pulse peak field strength, accurately cover half of the precession period with the pulse width, and slide the spin vector along the target Zeeman level potential well to trigger directional energy level flip.
[0043] It should be noted that, in the embodiments, the Zeeman level resonant submodule specifically includes: The spin initial state freezing unit is used to generate a spin initial state solidification effect by phase locking of the precession trigger field. The initial phase of the spins of all NV color center electrons is forced to zero, the spin vector direction is parallel to the normal of the polarization plane of the trigger field, and the quantum coherence time is extended to the microsecond level, forming a spacetime aligned spin array.
[0044] The frequency-selective resonant unit is used to input the target Zeeman energy level difference into the Larmor frequency converter. The energy level difference value is mapped to the electron gyromagnetic ratio multiple. Spatial gradient correction of the target conductor's magnetic field is applied, and the target-specific Larmor frequency is output.
[0045] The precession trajectory convergence unit is used to coordinate the spin array in space and time under the excitation of the target Larmor frequency. The spins of the matched frequency generate coherent precession, while the spins of the detuned frequency are suppressed due to phase dispersion. The precession trigger field maintains the initial boundary conditions and generates a spirally convergent precession trajectory loop, the diameter of which increases linearly with the pulse duration.
[0046] The current reconstruction engine system 103 is used to input the fluorescence attenuation spectrum collected through the optical tunneling channel and the residual resonant component of the compensated microwave pulse into a dual-channel correlation filter. The Zeeman splitting frequency shift is extracted from the fluorescence attenuation spectrum, the intrinsic magnetic field strength of the resonant component is analyzed, and a frequency shift-field strength nonlinear mapping table is established.
[0047] Optionally, in some embodiments, the current reconstruction engine system 103 specifically includes: The fluorescence lifetime gradient analysis subsystem is used to input the fluorescence attenuation spectrum collected by the optical tunneling channel into the lifetime-frequency shift converter, extract the time series of the inflection points of the attenuation curve, obtain the lifetime gradient change rate between adjacent inflection points, map the gradient extrema points to the Zeeman splitting characteristic frequency shift, and establish the frequency shift fingerprint sequence.
[0048] The resonant residual topology analysis subsystem is used to compensate for the residual resonant components of microwave pulses. After the pulse decays, the free induction attenuation signal is separated by the eddy current texture resolver, the time-domain envelope shape of the resonant residual is extracted, the intrinsic magnetic field strength scalar is calculated based on the envelope curvature radius, and the field strength topology map is generated.
[0049] A nonlinear coupled field construction subsystem is used to input the frequency shift fingerprint sequence and field strength topology map into a quantum correlation projector. The frequency shift sequence is sorted according to the diamond lattice orientation, and the field strength map is rescaled according to the stress distribution to establish a three-dimensional correlation point cloud of frequency shift and field strength.
[0050] The mapping table solidifies the output subsystem, which is used to correct the frequency shift-field intensity three-dimensional correlated point cloud through the stress-frequency shift coupling coefficient. The coefficient is derived from the real-time deformation data of the corrugated substrate. The point cloud is compressed along the stress gradient direction, and the nonlinear bandgap equation is used to fit the point cloud distribution to output the frequency shift-field intensity hyperbolic mapping table.
[0051] This embodiment uses fluorescence lifetime gradient analysis instead of traditional Fourier frequency shift analysis, inverts the intrinsic magnetic field strength using the resonant residual envelope, and describes the essential characteristics of the Zeeman frequency shift using stress-coupled hyperbolic equations. The final mapping table directly drives current density reconstruction.
[0052] The nonlinear coupled field construction subsystem specifically includes: The lattice principal axis projection component is used to input the frequency shift fingerprint sequence into the lattice orientation classifier to identify the lattice coordinates of the NV color center on the diamond substrate, group the frequency shift data by crystal orientation, and project the data of the same group along the crystal axis to generate a lattice-ordered frequency shift array, whose data point density is inversely proportional to the interplanar spacing.
[0053] The stress micro-region compression component is used to drive the field strength rescaling engine based on real-time deformation data of corrugated substrates. It extracts the compressive strain rate of each region of the substrate, divides the field strength topology map into strain micro-regions, scales the field strength value proportionally with the zero strain region as a reference, and outputs the stress invariant field strength field.
[0054] A 3D point cloud synthesis component is used for a lattice-ordered frequency shift array and a stress-invariant field strength input spatial frequency interleaver. The X-axis is the lattice-ordered frequency shift value and the frequency shift dimension; the Y-axis is the rescaled field strength value and the field strength dimension; and the Z-axis is the spatial position entropy, reflecting the distribution density of the measurement points. This forms a frequency shift-field strength-entropy correlated point cloud, and the point spacing characterizes the measurement confidence.
[0055] The stress micro-zone compression component specifically includes: The strain field feature extraction sub-component is used to input real-time deformation data of the corrugated substrate into the strain gradient resolver, identify the normal displacement contour lines on the substrate surface, obtain the displacement change rate of adjacent measurement points, and extract the compressive strain rate distribution cloud map, with negative values indicating the compressive state.
[0056] The field strength micro-region adaptive sub-component is used to compress the strain rate contour map-driven topology map segmenter. It divides micro-regions with the strain rate zero line as the boundary. Each micro-region contains constant strain rate characteristics. It divides the original field strength topology map into the same grid and generates a strain-field strength coupled micro-region array.
[0057] The reference scaling execution subcomponent is used for the strain-field intensity coupled array input field intensity invariant converter. It selects the zero strain rate micro-region as the reference field intensity value, multiplies the field intensity value of the compressive state micro-region by (1 + absolute strain rate), and divides the field intensity value of the tensile state micro-region by (1 + absolute strain rate). The output stress invariant field intensity field maintains the original topology in its spatial continuity.
[0058] The field strength micro-area adaptive sub-component specifically includes: The zero-value line boundary generation module is used to compress the strain rate distribution cloud map input contour topology extractor, locate the continuous spatial trajectory with a strain rate value of zero, obtain a smooth segment with a trajectory curvature radius greater than the critical threshold, extend the smooth segment into a closed curve, and generate a strain-neutral boundary, whose closed region contains uniform strain characteristics.
[0059] The micro-region growth control module is used to drive the field intensity map grid generator with strain neutral boundary. It takes each closed boundary as the core growth region and expands equidistantly along the boundary normal to generate concentric rings. The width of the rings is inversely proportional to the strain gradient modulus, forming a strain homogeneous micro-region grid.
[0060] The field strength data remapping module is used to perform sub-pixel resampling of the original field strength topology map based on the strain homogeneous grid, interpolate the median field strength in each micro-region, smoothly transition the field strength values at the boundary of adjacent micro-regions, preserve the spatial frequency characteristics of the original field strength, and output a strain-field strength coupled micro-region array.
[0061] The combined electrical quantum current transformer in this embodiment achieves environmental interference suppression. The micro-deformation compensation mechanism of the corrugated diamond substrate and the optical tunneling channel of the magnesium fluoride waveguide layer work together to solve the problem of NV color center energy level drift caused by the deformation of the high-voltage insulating cylinder, ensuring the signal stability of the quantum sensing head under mechanical stress. The triaxial ferrite grid array actively cancels power frequency electromagnetic interference by capturing eddy current interference fields and generating reverse compensation microwave pulse groups, avoiding the volume and weight costs of traditional shielding methods. High-fidelity quantum state transmission: The optical tunneling channel formed by helium ion beam injection optimizes the fluorescence collection efficiency of NV color centers, and the borosilicate glass buffer shell further isolates the disturbance of waveguide refractive index by external stress, ensuring the signal-to-noise ratio of the fluorescence attenuation spectrum. Dynamic magnetic field decoupling and reconstruction: The rotating magnetic field decoupling system generates compensation microwave pulses in real time through the interference field gradient vector, triggering quantum state deentanglement to eliminate the cross magnetic field coupling effect. The current reconstruction engine uses a dual-channel correlation filter to synchronously analyze the Zeeman frequency shift and intrinsic magnetic field strength, and directly outputs the current value through a nonlinear mapping table, avoiding the problem of integral error accumulation in traditional transformers. System-level integration adaptability and adaptive packaging design allow the quantum sensor head to be directly embedded in the insulating cylinder of the combined electrical appliance. The thermal expansion matching characteristics of the corrugated structure avoid packaging failure caused by temperature cycling, meeting the compact installation requirements of GIS equipment.
[0062] After the modules work together, the final technological breakthrough is: under the combined electrical conditions of high voltage and strong electromagnetic interference, a wide bandwidth of current is achieved through quantum state manipulation and active compensation mechanism, covering DC to harmonics, with high precision, and real-time sensing based on the Zeeman effect at the atomic level without magnetic saturation.
