DOI: 10.1007/s10773-020-04687-8
Abstract: Based on the solvable dynamical model for quantum measurement process, we consider three uncoupled particles interacting with their local one-dimensional (1D) spin arrays. Here the 1D spin arrays can be regarded as the local phase… read more here.

DOI: 10.1016/j.optcom.2016.12.002
Abstract: Abstract It has been shown that a nearly pure Greenberger–Horne–Zeilinger (GHZ) state could be distilled from a large (even infinite) number of GHZ-diagonal states that can be obtained by depolarizing general multipartite mixed states (non-GHZ-diagonal… read more here.

DOI: 10.1364/oe.25.018581
Abstract: Based on the circuit including linear optical elements, a fault-tolerant distribution of GHZ states against collective noise among three parties is proposed. Additionally, two controlled DSQC protocols using the shared GHZ states as quantum channels… read more here.
