International Journal of Theoretical Physics Aims and scope Submit manuscript

Abstract

By swapping the entanglement of χ-type state, we propose a quantum key distribution protocol, in which only Alice needs to prepare χ-type states and transmit a particle sequence. Both Alice and Bob need to perform χ-type state measurements.
