Perfect Discrimination of Non-Orthogonal Quantum States via Adaptive Post-Measurement Queries
Hanwool Lee, Teiko Heinosaari
A set of pairwise non-orthogonal quantum states cannot be perfectly discriminated, and this remains true even when one bit of classical partial information is available prior to th…

Semi-Device-Independent Certification for Nonlocality without Entanglement
Hanwool Lee, Joonwoo Bae
In this work, we present the framework for demonstrating and certifying the distinction between measurements in an entangled basis, called global measurements, and local operations…

Nonclassical traits in multi-copy state discrimination
Tim Achenbach, Leevi Leppäjärvi, Hanwool Lee +1
Quantum state discrimination is a fundamental information processing task that serves as a key component in many applications while also carrying foundational significance. In this…
