研究目的
Investigating the design of powerful quantum error correction codes (QECCs) for stabilizing and protecting fragile qubits against quantum decoherence by exploiting a concatenated code structure that invokes iterative decoding, aiming to approach the hashing bound.
研究成果
The paper concludes that the proposed quantum irregular convolutional code (QIRCC) can be dynamically adapted to match any given inner code using EXIT charts, achieving a performance close to the hashing bound. The QIRCC-based optimized design is capable of operating within 0.4 dB of the noise limit, demonstrating significant improvement over existing designs.
