Abstract
Description
Technical Field
[0001] This invention relates to the fields of quantum information processing, quantum storage, continuous variable quantum optics, Raman quantum storage, intelligent control, physical information neural networks, machine learning-assisted quantum experiments, and real-time feedback control. Specifically, it relates to a method and system for optimizing the control of quantum memories based on physical information neural networks. Background Technology
[0002] Quantum memories are key devices in quantum communication, quantum computing, quantum networks, and quantum-enhanced sensing. Their performance is typically determined by the following metrics: 1. Storage efficiency; 2. Storage lifetime; 3. Storage bandwidth; 4. Output state fidelity. Taking Raman quantum memories as an example, optical quantum states are mapped to atomic spin wave modes by writing control light, and then converted back to optical modes by reading control light. This process is affected by various parameters, including control light power, detuning, pulse shape, optical depth, ACStark shift, phase noise, four-wave mixing noise, mode matching, and probe system stability. Traditional optimization methods typically rely on manual parameter scanning, single-variable empirical optimization, offline numerical simulation, pre-calibrated lookup tables, or low-dimensional feedback control. These methods have the following drawbacks: 1. Low efficiency in high-dimensional parameter space search; 2. Difficulty in simultaneously optimizing efficiency, noise, bandwidth, and fidelity; 3. Difficulty in deriving the optimal control input from the target performance; 4. Difficulty in adapting to different input quantum states and different read / write configurations; 5. Difficulty in unifying offline physical simulation results, historical experimental data, and real-world automatic system control.
[0003] Existing research on quantum memory optimization has shown that theoretical models, pulse optimization, phase compensation, spin wave spatial distribution design, reverse readout configurations, parameter scanning, or experimental calibration can improve storage efficiency and reduce noise. However, the spin wave spatial distribution typically cannot be directly measured experimentally and must be inferred and constrained through quantum memory dynamics equations, Hankel mappings, or numerical simulations. Furthermore, a long-standing criticism of quantum memories is that their optimal control requires prior information about the temporal patterns of the input signal, a requirement often unmet in practical applications. Relying solely on real-time feedback from a real system for high-dimensional searches results in numerous experiments, slow convergence, and susceptibility to system drift.
[0004] Therefore, a new method for optimizing the control of quantum memories is urgently needed: first, train the PINN model using physical equations and measurable data so that it can learn to deduce the input signal and optimal control under limited control input and output of the quantum memory; then, in the deployment phase, use the trained PINN model to achieve the optimal control output and apply this output to the real quantum memory system to achieve automatic control and experimental feedback correction.

[0035] Example 2 Example 2 is a preferred example of Example 1. This invention provides an optimized control system for quantum memory based on a physical information neural network, such as... Figures 1 to 3 As shown, it includes the training phase and the deployment control phase.
[0036] The training phase includes: The training data construction module is used to acquire or generate training data, which includes sampling points of the quantum storage dynamics equation, boundary conditions, initial conditions, numerical simulation data, historical experimental data, and measurable performance data. The physical information neural network training module is used to write the physical equation residuals, boundary condition residuals, initial condition residuals, data fitting errors, target performance loss, and control regularization terms into the loss function to train the PINN model. The model validation module is used to verify the training PINN's ability to predict the input signal light field, optimal control light field, storage efficiency, readout efficiency, additional noise, phase drift, and output state fidelity using experimental data.
[0037] The deployment control phase includes: The control light generation module keeps the weights of the trained PINN model fixed during the deployment control process and applies them to the real quantum memory to deduce the optimal control parameters for the control input. The module generates write control light, read control light, or other auxiliary control light based on the deduced control parameters. A real quantum memory module for receiving, storing, and reading optical quantum states; The experimental measurement module is used to acquire data related to input state, output state, reference pulse, noise, efficiency, readout efficiency, phase, or fidelity. The automatic feedback execution module is used to determine whether to continue calling the trained PINN to re-infer the control input based on the actual system measurement results, or to make minor adjustments to the control parameters.
[0038] The core function of PINN is not continuous online training during the operation of the real physical system, but rather, after training, it is used to predict the output performance corresponding to the control inputs and to infer or search for the optimal control inputs required by the real physical system. The online components during the operation of the real system mainly involve measurement, control input updates, and feedback execution.
[0039] In one implementation, the training loss function of PINN includes:
[0040] in: : Residuals of the quantum storage dynamics equations; : Measurable experimental data fitting loss; Boundary condition loss; Initial condition loss; : Regularization terms that control optical smoothness, energy limitation, bandwidth limitation, or physical realizability; , , , , , Weights of each loss item.
[0041] Control input inversion based on trained PINN After training, PINN can be represented as:
[0042] in, For PINN network; For fixed network parameters after training, This indicates the output optical quantum state, experimental platform state, or known system parameters. This indicates that the control input is not optimized. This represents the output control optical field, input signal optical field, Raman detuning, phase, control optical power, storage time, noise, and fidelity predicted by PINN.
[0043] Seeking The system then converts these signals into physical control signals executable by an AWG, AOM, EOM, RF source, laser frequency controller, or phase-locked module, and applies them to the real quantum memory. The real system measurements are used to evaluate the control effect and can serve as data for subsequent batch retraining or model calibration, but online updates of the PINN weights are not required in each experimental cycle.
[0044] In a preferred embodiment, the Raman storage process includes optical loss, spin wave decoherence, four-wave mixing noise, AC Stark shift, control optical phase drift, mode mismatch, etc. It can be described by the following coupling equations:
[0045]

[0047] During the read phase, the read control light is preferably configured to propagate in the opposite direction to the write control light. The trained PINN uses the reverse read configuration, read control light waveform, read phase, and read timing as optimizable control inputs; the real system evaluates the control performance using measurable output light field, read efficiency, noise, and phase data.
[0048] PINN Training and Deployment Control In this embodiment, training samples are first constructed. Each training sample includes an input state description. Control input Boundary conditions, initial conditions, and output performance data obtained from numerical simulation or experiments. Control inputs may include:
[0049] in, To control the optical pull ratio frequency, To read the control light pull ratio frequency, To write control optical phase, To read the control light phase, Disharmony, To control the optical power, To read and control optical power; PINN is then trained using a loss function, and the network parameters are fixed after training. The trained PINN network is then deployed to the experimental control computer. Given the output state and target performance, the network directly outputs the optimal control. and will Converted into executable signals for AWG, AOM, EOM, RF source, and laser frequency controller.
[0050] After the real quantum storage system performs write, store, and read operations, the experimental measurement module acquires the output light field, storage efficiency, read efficiency, added noise, phase drift, and fidelity. The measurement results are used to assess the control effect and can be stored in a dataset for subsequent offline retraining or model calibration. During the deployment phase, training the PINN weights in each round of experiments is not required.
[0051] In Raman storage, control light may cause AC Stark shift, resulting in a phase shift of the spin wave:
[0052] in, The phase shift is caused by AC Stark shift. Two-photon detuning caused by AC Stark shift; During the training phase, PINN uses the phase evolution equation, reference pulse measurement data, zero-beat measurement data, or output phase measurement data together to learn the effects of AC Stark shift, two-photon detuning, and phase noise on output performance.
[0053] During the deployment phase, the trained PINN, based on the current measurable state and the target output phase, inversely derives the phase compensation for writing to or reading from the control light:
[0054] in, For the final control phase, The phase shift is caused by AC Stark shift. This is a random phase shift; In this embodiment, dynamic phase modulation is used as one of the control variables derived from PINN after training to compensate for ACStark shift and phase drift.
[0055] Arbitrary input waveform and hardware distortion correction: In this embodiment, the write control light and the read control light are represented as follows:
[0056]
[0057] in, The basis functions can be, for example: Gaussian, Hermite-Gaussian, B-spline, Fourierbasis, top-hat-like smooth pulse, Chebyshev nodal interpolation waveform, or experimentally achievable AWG waveform basis functions. This refers to the mode coefficients for the k-th time mode of the control light. The total number of patterns To read the mode coefficients in the k-th time mode of the control light, To write the final Rabi frequency of the control light, To read the final Rabi frequency of the control light; During the training phase, calibration data from AWG, AOM, EOM, or RF links can be used to train the hardware distortion correction module. Alternatively, Chebyshev node dimensionality reduction, spline interpolation, residual neural network hardware correction, differential evolution, or Bayesian optimization can be used as control input parameterization and search strategies.
[0058] During the deployment phase, the trained PINN derives its coefficients based on the target storage efficiency, output waveform, and fidelity.
[0059] This is then converted into a control optical waveform executable by real hardware. This method ensures that the control optical waveform satisfies both the quantum storage performance objectives and the power, bandwidth, and smoothness constraints of the experimental system.
