Distinguishability, Ensemble Steering, and the No-Signaling Principle
Joonwoo Bae
We consider a fundamental operational task, distinguishing systems in different states, in the framework of generalized probabilistic theories and provide a general formalism of mi…
Structure of minimum-error quantum state discrimination
Joonwoo Bae
Distinguishing different quantum states is a fundamental task having practical applications for information processing. Despite the efforts devoted so far, however, strategies for…
Optimal Discrimination of Qubit States - Methods, Solutions, and Properties
Joonwoo Bae, Won-Young Hwang
We show a geometric formulation for minimum-error discrimination of qubit states, that can be applied to arbitrary sets of qubit states given with arbitrary a priori probabilities.…
No-signaling Quantum Key Distribution: Solution by Linear Programming
Won-Young Hwang, Joonwoo Bae, Nathan Killoran
We outline a straightforward approach for obtaining a secret key rate using only no-signaling constraints and linear programming. Assuming an individual attack, we consider all pos…
