摘要：
We study spin transport properties in non-magnetic heterostructures in the presence of different spin-orbit interactions. For an unpolarized beam with zero angle of incidence, the transmitted spin-up and spin-down electrons will propagate in the same direction with similar amplitudes and different phases. The two beams will interfere with each other after passing through a certain distance of spin-orbit region. This effect just resembles the interference of polarization of light passing through wave plate. This quantum interference will shed light on quantum information processing and quantum computation.
