Quantum Walk of Two Quantum Particles on One Dimensional System
Yongmei Zhang, Junjie Xiao, Dongsheng Hu · Journal of Quantum Information Science · 2013
We study two particle quantum walks on one dimensional chain.Probability distribution of two particle quantum walks is dependent on the initial state, and symmetric quantum walk or asymmetric quantum walk is analogous to that of one particle quantum walk.The quantum correlation probability is much different from classical coincidence probability.The difference reflects quantum interference between two particles.
