Contribution

It proposes a novel secret sharing protocol based on Grover's algorithm, generalizing previous schemes to n-qubits for enhanced quantum security.

Findings

Scheme demonstrated for four qubits with multiple marked states

Generalized to n-qubits for broader applicability

Utilizes quantum parallelism and entanglement for security

Abstract

Some of the secret sharing schemes having unique quantum features like parallelism and entanglement are supposed to be relatively secure. Different schemes proposed by various researchers over the years have features which could be specific to the nature and need of a situation. Following Hsu's proposed scheme we propose a secret sharing scheme using Grover's search algorithm for a four qubit system with several marked states. Further, the scheme has been generalised to an n-qubit syatem.
