A novel three party Quantum secret sharing scheme based on Bell state sequential measurements with application in quantum image sharing
This work addresses secure secret sharing in quantum cryptography, offering a novel protocol with experimental validation, though it appears incremental as it builds on existing quantum techniques.
The authors tackled the problem of secure quantum secret sharing by proposing a scheme based on Bell state entanglement and sequential projection measurements, which was experimentally demonstrated on IBM-QE cloud platforms and shown to be robust against eavesdropping with comparative analysis supporting its efficiency.
In this work, we present a quantum secret sharing scheme based on Bell state entanglement and sequential projection measurements. The protocol verifies the $n$ out of $n$ scheme and supports the aborting of the protocol in case all the parties do not divulge in their valid measurement outcomes. The operator-qubit pair forms an integral part of the scheme determining the classical secret to be shared. The protocol is robust enough to neutralize any eavesdropping on a particular qubit of the dealer. The experimental demonstration of the scheme is done on IBM-QE cloud platform with backends \texttt{IBMQ\_16\_Melbourne} and \texttt{IBMQ\_QASM\_SIMULATOR\_V0.1.547} simulator. The security analysis performed on the scheme and the comparative analysis supports our claim of a stringent and an efficient scheme as compared to some recent quantum and semi-quantum techniques of secret sharing.
