Product states and Schmidt rank of mutually unbiased bases in dimension six
Lin Chen, Li Yu
We show that if a set of four mutually unbiased bases (MUBs) in exists and contains the identity, then any other basis in the set contains at most two product states…
The Birkhoff theorem for unitary matrices of arbitrary dimensions
Stijn De Baerdemacker, Alexis De Vos, Lin Chen +1
It was shown recently that Birkhoff's theorem for doubly stochastic matrices can be extended to unitary matrices with equal line sums whenever the dimension of the matrices is prim…
Entangling and assisted entangling power of bipartite unitary operations
Lin Chen, Li Yu
Nonlocal unitary operations can create quantum entanglement between distributed particles, and the quantification of created entanglement is a hard problem. It corresponds to the c…
Implementation of bipartite or remote unitary gates with repeater nodes
Li Yu, Kae Nemoto
We propose some protocols to implement various classes of bipartite unitary operations on two remote parties with the help of repeater nodes in-between. We also present a protocol…
