Toward Practical Quantum Secure Direct Communication: A Quantum-Memory-Free Protocol and Code Design

2020 · IEEE Transactions on Communications

Quantum secure direct communication (QSDC) is capable of direct confidential communications over a quantum channel, which is achieved by dispensing with the key agreement channel of the well-known quantum key distribution (QKD). However, to make …

Spatially coupled LDPC-BCH codes in quantum secure direct communications

2019 · Journal of Tsinghua University(Science and Technology)

Quantum secure direct communication systems are limited by high erasure probabilities and low receiving probabilities due to the high light source losses in the optical elements and optical fibers. A channel mitigation method based on …
