Quantum Signature Scheme Using a Single Qubit Rotation Operator

초록

We present a quantum signature scheme using a single qubit rotation operator. In this protocol, the trusted center confirms the quantum signature and thus conforms with other quantum signature schemes. Utilizing the unitary properties of a single qubit rotation operator and Pauli operators, our protocol provides signature security and enhances the efficiency of communication. In addition, our protocol - using only a single qubit measurement - facilitates the ease of implementation and enhances convenience for users. The security of the protocol is analyzed.
