Quantum key distribution without alternative measurements and rotations
Fei Gao, Fenzhuo Guo, Qiaoyan Wen, Fuchen Zhu
abstract: A quantum key distribution protocol based on entanglement swapping is
proposed. Through choosing particles by twos from the sequence and performing
Bell measurements, two communicators can detect eavesdropping and obtain the
secure key. Because the two particles measured together are selected out
randomly, we need neither alternative measurements nor rotations of the Bell
states to obtain security.
