Comment on “Protocol for Direct Counterfactual Quantum Communication”

Reply to comment on Y-00 quantum secure communication protocol

Recently, a criticism of the Yuen protocol (αη scheme) was made. This letter shows that the claim by Nishioka, and Imai group(Mitsubishi and University of Tokyo) is incorrect before they discuss whether αη scheme is quantum or classical. This misunderstanding comes from that these authors disregard the concept of signal detection theory and the basic concept of Y-00. Several industries have sta...

Quantum Bit Commitment Protocol Based on Counterfactual Quantum Cryptography

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 presented by QBC’s no-go theorem. Our protocol is simple, and probably gives a new way of constructing QBC protocol.

Quantum Direct Communication

Quantum Secure Direct Communication with Quantum Memory.

Quantum communication provides an absolute security advantage, and it has been widely developed over the past 30 years. As an important branch of quantum communication, quantum secure direct communication (QSDC) promotes high security and instantaneousness in communication through directly transmitting messages over a quantum channel. The full implementation of a quantum protocol always require...
