A novel three-party quantum secret sharing scheme based on Bell state sequential measurements with application in quantum image sharing

Abstract

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 IBMQ_16_Melbourne and IBMQ_QASM_SIMULATOR_V0.1.547 simulator. The security analysis performed on the scheme and the comparative analysis support our claim of a stringent and an efficient scheme as compared to some recent quantum and semi-quantum techniques of secret sharing.
