Witness robustness: An operational quantifier of measurement resources via free state discrimination
Jingsong Ao, Aby Philip, Alexander Streltsov
The paper defines the witness robustness of quantum measurements as a resource measure based on free‑state witnesses and shows it quantifies the maximal advantage a measurement giv…
Quantum Resources and Performance in the Initialization-Free Bernstein-Vazirani Algorithm
Haesol Han, Alexander Streltsov, Soojoon Lee
Naseri et al. [Phys. Rev. A 106, 062429 (2022); arXiv:2205.13610] studied which quantum resources in initial states are essential for the probabilistic Bernstein-Vazirani (BV) algo…
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…
Optimality of universal conclusive entanglement concentration protocols
Alexandre C. Orthey, Aby Philip, Tulja Varun Kondra +1
Entanglement concentration is essential for quantum technologies, yet rigorous bounds on the success probability for universal protocols (those requiring no prior knowledge about t…
Asymptotic Limits of Entanglement Transmission
Piotr Masajada, Aby Philip, Alexander Streltsov
Reliable distribution of quantum entanglement over long distances is a central challenge in quantum information science, fundamentally limited by decoherence in noisy communication…
