Total Ordering of Resources: A Quantum-Classical Separation
Jingsong Ao, Julio I. de Vicente, Alexander Streltsov
A central goal in quantum information science is understanding which physical states can be converted into others. The ideal scenario would be a totally ordered system, where every…
PPT Entanglement with Correlated Catalysis: Monotones and Irreversibility
Jingsong Ao, Aby Philip, Alexander Streltsov
Quantum catalysts can overcome otherwise impossible quantum state transformations without being consumed, and allowing them to become correlated with the output makes this assistan…
Witness robustness: An operational quantifier of measurement resources via free state discrimination
Jingsong Ao, Aby Philip, Alexander Streltsov
We introduce the witness robustness of quantum measurements, a resource quantifier whose admissible noise consists of tuples of free-state witnesses rather than physical measuremen…
Resourcefulness without Resource: Geometric Origins and Robustness
Jingsong Ao, Aby Philip, Alexander Streltsov
A prevailing intuition holds that quantum protocols using only free states confer no operational advantage. This intuition is contradicted by free-state discrimination gaps in whic…
Advantage of flexible catalysis for entanglement and quantum thermodynamics
Jingsong Ao, Aby Philip, Alexander Streltsov
Understanding the fundamental limits of state convertibility is crucial for establishing the boundaries of quantum information processing and thermodynamic efficiency. While auxili…
