Definitely Not That One: The Art of Antidistinguishing Quantum States

Jamie Sikora | Virginia Tech

Identifying quantum states is one of the oldest problems in quantum information theory. In this work, we explore a variation of this task: rather than determining which state a system is in, we seek to identify a state that it is not. A set of quantum states is said to be antidistinguishable if this inverse guessing game can be won with certainty. We establish tight bounds characterizing when a set of pure states must be antidistinguishable, as well as when it is impossible.

This is joint work with Vincent Russo and Nathaniel Johnston.
