An Implementable Protocol of Quantum Bit String Commitment
Toyohiro Tsurumaru · arXiv (Cornell University) · 2004
Quantum bit string commitment[A.Kent, Phys.Rev.Lett., 90, 237901 (2003)] or QBSC is a variant of bit commitment(BC). In this paper, we propose a new protocol of QBSC which can be implemented using the currently available technology, and prove its security under the same security criteria as discussed by Kent. QBSC is a generalization of BC, but with slightly weaker requirement, and our proposed protocol is not intended to break the no-go theorem of quantum BC.
