The complexity of perfect quantum state classification
Nathaniel Johnston, Benjamin Lovitz, Vincent Russo +1
The problem of quantum state classification asks how accurately one can identify an unknown quantum state that is promised to be drawn from a known set of pure states. In this work…

Quantum nonlocality without entanglement and state discrimination measures
Shayeef Murshid, Tathagata Gupta, Vincent Russo +1
An ensemble of product states is said to exhibit "quantum nonlocality without entanglement" if it cannot be optimally discriminated using local operations and classical communicati…
