This abstract first appeared for US patent application 20240046139 titled 'Method for Transmitting Information Through Topological Quantum Error Correction Based on Multi-Space-Time Transformation

Simplified Explanation

The present disclosure describes a method for transmitting information using topological quantum error correction based on multi-space-time transformation. The method involves initializing quantum information, detecting and correcting errors in quantum information transmission, and decoding the information. The design of this method allows for easy detection and correction of errors, improving information safety. It only requires an increase in the number of devices for generating quantum states, and a stabilizer can be used for error detection, measurement, and correction. The encoding state of the encoded qubit remains unchanged during odd/even parity measurement, ensuring the security of the encoded qubit. Additionally, a double-layer convolutional neural network model can be used to find an error correction chain with the best effect in an adversarial network.
