Implementable quantum-bit-string commitment protocol
Toyohiro Tsurumaru
Quantum-bit-string commitment [A. Kent, Phys. Rev. Lett. 90, 237901 (2003)] (QBSC) is a variant of bit commitment (BC). In this paper, we propose a QBSC protocol that can be implemented using currently available technology and prove its security under the same security criteria as discussed by Kent. QBSC is a generalization of BC, but has slightly weaker requirements, and our proposed protocol is not intended to break the no-go theorem of quantum BC.
