Description
Technical Field
[0001] This invention relates to the fields of quantum information processing, topological physics manipulation, quantum communication, and quantum device manufacturing. Specifically, it relates to a complete engineering method and system that integrates topological material orientation screening, topological protection device manufacturing, topological stability control, and quantum teleportation protocols. This invention can be applied to quantum computing, quantum communication networks, distributed quantum information processing, and metropolitan quantum internet, and is particularly suitable for constructing high-fidelity, long-distance quantum teleportation systems with topological protection. Background Technology
[0002] Quantum teleportation, as one of the core protocols in quantum information science, is a fundamental technological means for realizing distributed quantum computing and quantum communication networks. Since Bennett et al. proposed the theoretical scheme in 1993, quantum teleportation has been experimentally verified on various physical platforms such as photons, atoms, and superconducting qubits. However, existing quantum teleportation technologies still face a series of fundamental challenges: (a) The problem of quantum decoherence The core resource of quantum teleportation—the quantum entangled state—is highly susceptible to decoherence due to environmental noise. During transmission, the fidelity of the entangled state decreases sharply with increasing distance and transmission time. Traditional schemes rely on quantum error-correcting codes to suppress errors, but error correction is extremely costly and requires a large number of physical qubits to encode a single logical qubit. (ii) Entanglement with demanding resource requirements Standard quantum teleportation protocols require the sender and receiver to pre-share a maximally entangled state (such as a Bell state). In practical engineering, preparing and maintaining high-quality entangled pairs is extremely difficult, and the quality of the entangled pairs directly affects the transmission fidelity. Existing schemes have stringent requirements for the quality of entangled resources, limiting the practical application of the system. (iii) The various components of the system are isolated from each other. In existing technologies, the selection of topological materials, the fabrication of topological devices, the control of quantum state stability, and the execution of teleportation protocols are all independent processes, lacking a unified mathematical framework and engineering methodology. Design methods cannot directly guide the selection of manufacturing process parameters, the tolerance window of the manufacturing process fails to match the system's topology protection bandwidth, and there is a lack of real-time monitoring and protection mechanisms for the integrity of the topology during transmission. (iv) Insufficient fidelity in long-distance transmission Although recent studies have achieved inter-chip quantum teleportation over fiber optic distances of up to 12.3 kilometers, the average fidelity is only about 81%. The fidelity degradation problem becomes even more severe over longer distances and with more complex network topologies. The introduction of topology protection holds promise for fundamentally improving the fidelity of long-distance transmission. (v) Lack of end-to-end closed-loop control Existing quantum teleportation systems lack a complete closed-loop feedback mechanism from material preparation to teleportation execution. Parameter drift in each stage cannot be monitored and dynamically compensated in real time, making it difficult to guarantee the system's consistency and repeatability. In recent years, several cutting-edge studies have provided key theoretical support for topology-protected quantum teleportation: (1) The topology-protected teleportation protocol based on Majorana Zero Modes (MZMs) proposed in 2025 achieves topology protection through projection parity measurement without dynamic weaving; (2) Research in 2024 found that the stability of topological matter can be maximized by using electromagnetic duality, so that even infinitely weak entanglement pairs can complete teleportation; (3) Robust teleportation of topological rotating surface codes was demonstrated on a 125-qubit superconducting quantum processor in 2025; (4) On-chip photon topology loading and entanglement-assisted transmission were realized in 2025; (5) Symmetry-protected topological order (SPT) has been proven to be a necessary condition for standard quantum teleportation protocols. To address the aforementioned problems, this invention provides a topology-protected quantum teleportation end-to-end engineering method and system. Based on first-principles derivations of the projection axiom, this invention integrates topology material selection, topology-protected device fabrication, topology stability control, and quantum teleportation protocol execution into a unified technical chain, using complex projection weights logarithms. To unify mathematical language, topology protects bandwidth. To unify the calibration benchmark and achieve closed-loop control across the entire process from theoretical design to engineering implementation. Summary of the Invention

Example 2: Projection Parity Measurement of Teleportation Based on Majorana Null Modes This embodiment demonstrates how to achieve topology-protected quantum teleportation using spatially separated Majorana zero modes. Step 1: Fabrication of Majorana zero-mode devices Using the second-level topology-protected lithography technique of this invention, Majorana zero-mode (MZM) devices are fabricated in a semiconductor-superconductor hybrid nanowire system. The devices comprise spatially separated pairs of Majorana zero modes, the spatial separation distance of which can be determined according to the topology-protected bandwidth. Optimize the design. Step 2: Non-local information encoding Logical quantum information is stored in the parity of Majorana zero modes through nonlocal encoding. Nonlocal encoding prevents local noise from affecting all Majorana modes simultaneously, thus achieving natural fault tolerance. Step 3: Projection Parity Measurement Projective parity measurements are performed on spatially separated Majorana zero modes. This measurement operation requires no dynamic weaving and enables topology-protected quantum state transfer solely through measurement. Step 4: Topology Protection Transfer The decoherence rate decreases exponentially with the spatial separation distance of the Majorana mode. The parity stability of the Majorana zero mode is monitored in real time using the stability criterion of the third layer of this invention. When the criterion is not met, feedback adjustment (temperature / gate voltage) is triggered to maintain the topology protection state.

Feedback adjustments are triggered during drift to maintain the integrity of the SPT sequence.

Step 3: Weak entanglement state transfer By utilizing topological matter with maximized electromagnetic duality, quantum teleportation can be achieved even when the entanglement strength is extremely weak (infinitely weak). This scheme is applicable to Rydberg atom or superconducting quantum computing platforms. Step 4: Control of topological phase transition in mixed states By controlling the topological quantum phase transition of mixed states, additional degrees of freedom are provided for the dynamic optimization of state transfer fidelity. Example 5: Verification of a Quantum Processor Based on Topological Surface Codes This embodiment demonstrates how to achieve robust teleportation of topological surface codes on a superconducting quantum processor. Step 1: Preparation of Topological Rotational Surface Codes On a superconducting quantum processor, topological rotating surface codes are prepared using linear deep unitary circuits, with a maximum code distance of 7. Step 2: Logical State Implicit Transmission Achieving logical state teleportation with a code distance of up to 7 is achieved. The teleportation phase diagram is obtained by exceeding a finite threshold through uniformly tuned local entanglement gates. Step 3: Entanglement Threshold Raising Rotating coherent qubits can inject magical resources to increase the entanglement threshold and restore the dual symmetry of the topological phase. Step 4: Application of stability criteria The stability criterion of multilayer topological materials in the third layer of this invention is directly applied to the real-time monitoring of surface codes and extended to the stability control of multiple logic qubits. Example 6: Metropolitan Quantum Teleportation Based on Chip-Fiber Network This embodiment demonstrates how to achieve topologically protected quantum teleportation at the metropolitan scale using optical quantum chips and fiber optic networks. Step 1: Design and Manufacturing of Photonic Quantum Chips Using the topological phase diagram design method and topological protection lithography technology of the second layer of this invention, three quantum optical paths are designed and fabricated on a single silicon photonic chip: user node (time-slice encoded single photon generation), relay node (entangled photon pair generation + Bell state measurement BSM), and central node (projection measurement). Step 2: Chip-Fiber Network Architecture A three-node star-topology quantum network was established, with nodes connected by optical fibers, and a transmission distance of up to 12.3 kilometers. Step 3: Proactive Feedback and Compensation An active feedback system based on a variable optical delay line dynamically compensates for changes in fiber length, ensuring stable quantum interference for BSM measurements at relay nodes. Step 4: Enhance Topology Protection Integrating a topological photonic crystal structure into a quantum chip provides topological protection for photonic quantum states and resists environmental noise during optical fiber transmission. Step 5: Fidelity Verification The measured average fidelity is approximately 81%. With topology protection enhancement, the target fidelity can be increased to over 90%. Example 7: End-to-End Closed-Loop Feedback Integrated System This embodiment demonstrates how to integrate the various components of the aforementioned six embodiments into a unified end-to-end closed-loop control system. Step 1: Unified Data Feedback System Material screening parameters ( , ), Device manufacturing parameters ( , , Stability control parameters , ) and transfer execution parameters (fidelity) Transmission distance It is incorporated into a unified data feedback system. Step 2: Standardize the calibration benchmark Protect bandwidth with topology As a unified calibration benchmark for the entire link. It also serves as the basis for topological quality judgment in the material screening stage, the process tolerance window in the device manufacturing stage, the phase drift tolerance threshold in the stability control stage, and the theoretical lower limit benchmark for transfer fidelity. Step 3: Real-time monitoring and closed-loop adjustment The stability criterion at the third level of this invention is used to monitor each stage in real time. Deviation: When Deviation exceeds Time-triggered feedback adjustment (gate voltage / temperature / magnetic field); when Deviation Exceed When the transfer fidelity is lower than the target value, anion compensation or strain compensation is triggered; when the transfer fidelity is lower than the target value, entanglement resource optimization or topology protection enhancement is triggered. Step 4: End-to-end iterative optimization The non-destructive three-dimensional characterization results of the Talbot-Lau interferometer are used as verification feedback for the entire closed-loop process, realizing a complete closed loop of "screening → preparation → manufacturing → control → transfer → characterization → optimization". Terminology Explanation

Topology protection bandwidth (σ_θ) is the parametric width between nontrivial and trivial phases in the topology phase diagram. Majorana zero modes (MZMs) are zero-energy quasi-particle states existing in topological superconductors, exhibiting non-Abelian statistical properties. Projection parity measurement is the operation of parity projection measurement of spatially separated Majorana null modes. Symmetry-protected topological order (SPT) is a topologically ordered phase protected by symmetry.
