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…
Metainformation in Quantum Guessing Games
Teiko Heinosaari, Hanwool Lee
Quantum guessing games offer a structured approach to analyzing quantum information processing, where information is encoded in quantum states and extracted through measurement. An…
Sequential Quantum Maximum Confidence Discrimination
Hanwool Lee, Kieran Flatt, Joonwoo Bae
Sequential quantum information processing may lie in the peaceful coexistence of no-go theorems on quantum operations, such as the no-cloning theorem, the monogamy of correlations,…
