Are entanglement and quantum computer necessary for quantum bit commitment ?
. It was claimed that unconditionally secure quantum bit commitment is impossible due to quantum-computer-assisted-entanglement-attack Recently we have shown that quantum computer-assisted-entanglement-attack can be totally foiled by entanglement and quantum computer. Here we present an alternative un-entanglement based quantum bit commitment scheme. Although the scheme is unconditionally secur...

متن کاملHow Unconditionally Secure Quantum Bit Commitment Is Possible
Bit commitment involves the submission of evidence from one party to another so that the evidence can be used to confirm a later revealed bit value by the first party, while the second party cannot determine the bit value from the evidence alone. It is widely believed that unconditionally secure quantum bit commitment is impossible due to quantum entanglement cheating, which is codified in a ge...
