Unconditionally Secure Relativistic Quantum Qubit Commitment
Houquan Liu, Libo Yuan · Applied Sciences · 2021
Quantum qubit commitment is a stronger version of the quantum bit commitment. It is impossible to realize unconditionally secure quantum qubit commitment in nonrelativistic domain. In this paper, we propose an unconditionally secure relativistic quantum qubit commitment protocol for the first time, which will have some unique applications in the upcoming era of quantum network.
