Counterfactual Quantum Bit Commitment
Ya-Qi Song, Li Yang
We propose a framework of bit commitment protocol using a comparison scheme and present a compound comparison scheme based on counterfactual cryptography. Finally, we propose a cou…

Quantum Bit Commitment Protocol Based on Counterfactual Quantum Cryptography
Ya-Qi Song, Li Yang
We present a new quantum bit commitment (QBC) protocol based on counterfactual quantum cryptography. We analyze the security of this protocol, find that it can resist the attack pr…

Practical quantum oblivious transfer and bit commitment protocols
Ya-Qi Song, Li Yang
We propose a practical quantum oblivious transfer and a bit commitment protocols which replace the single-photon source with weak coherent pulses and allow error and loss in channe…
