摘要: We study the use of polar codes for both discrete and continuous variables Quantum Key Distribution (QKD). Although very large blocks must be used to obtain efficiency required by quantum key distribution, especially their implementation on generic ×86 Central Processing Units (CPUs) is practical. Thanks recursive decoding, they exhibit excellent decoding speed, much higher than large, irregular Low Density Parity Check (LDPC) implemented similar hardware, competitive with implementations same high-end Graphic (GPUs).
