Unconditionally secure quantum bit commitment using modified double-slit and unstable particles

Quantum Physics 2023-05-23 v1

Abstract

We note that the proof of the no-go theorem of unconditionally secure quantum bit commitment is based on a model which is not universal. For protocols not described by the model, this theorem does not apply. Using unstable particles and a modified double-slit setup, we construct such a protocol and show that it is unconditionally secure. In this protocol, the committer transfers no quantum states to the receiver.
