Is entanglement necessary to have unconditional security in quantum bit commitment ?
Arindam Mitra
TL;DR
This paper presents an un-entanglement based quantum bit commitment scheme that achieves unconditional security in commitment but fails to provide concealment, highlighting limitations in quantum cryptographic protocols.
Contribution
It introduces a simple un-entanglement based scheme demonstrating unconditional security in commitment but not in concealment.
Findings
Commitment is unconditionally secure.
Concealment is not achieved.
Un-entanglement based schemes have limitations.
Abstract
A simple un-entanglement based quantum bit commitment scheme is presented. Although commitment is unconditionally secure but concealment is not.
