DESCRIPTION:When can we distinguish quantum measurements perfe
ctly after only a finite number of queries? How to
calculate the diamond norm distance between von N
eumann measurements? During the seminar\, I will p
resent results on the discrimination of measuremen
ts with rank-one effects. I will focus on the disc
rimination of von Neumann measurements and SIC POV
Ms. I will elaborate on three approaches to the di
scrimination problem\, which are: symmetric\, unam
biguous\, and asymmetric discrimination. All of th
ese approaches will be considered in the single-sh
ot and multiple-shot scenarios. I will consider bo
th the parallel and adaptive schemes of discrimina
tion assuming that we can use the discriminated ch
annel a finite number of times. I will provide for
mulas for the optimal probability of correct discr
imination and indicate when the adaptive scheme is
essential for perfect discrimination.
