Semiquantum key distribution without invoking the classical party’s measurement capability

Semiquantum key distribution without invoking the classical party’s measurement capability In the existing semiquantum key distribution (SQKD) protocols, the both parties must measure qubits in some bases. In this paper, we show that the classical party’s measurement capability is not necessary by constructing an SQKD protocol without invoking the classical Alice’s measurement capability. In particular, we prove that the proposed SQKD protocol is completely robust against joint attacks. Compared with the existing SQKD protocols, the number of the quantum states sent by Alice and Bob is decreased. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

Abstract

In the existing semiquantum key distribution (SQKD) protocols, the both parties must measure qubits in some bases. In this paper, we show that the classical party’s measurement capability is not necessary by constructing an SQKD protocol without invoking the classical Alice’s measurement capability. In particular, we prove that the proposed SQKD protocol is completely robust against joint attacks. Compared with the existing SQKD protocols, the number of the quantum states sent by Alice and Bob is decreased.
