Non-destructive Orthonormal State Discrimination
We provide explicit quantum circuits for the non-destructive deterministic
discrimination of Bell states in the Hilbert space , where is
qudit dimension. We discuss a method for generalizing this to non-destructive
measurements on any set of orthogonal states distributed among parties.
From the practical viewpoint, we show that such non-destructive measurements
can help lower quantum communication complexity under certain conditions.Comment: 11 pages, 6 fugure
