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…
Analytic Rényi Entropy Bounds for Device-Independent Cryptography
Thomas A. Hahn, Aby Philip, Ernest Y. -Z. Tan +1
Device-independent (DI) cryptography represents the highest level of security, enabling cryptographic primitives to be executed safely on uncharacterized devices. Moreover, with su…
Optimizing entanglement distribution via noisy quantum channels
Piotr Masajada, Marco Fellous-Asiani, Alexander Streltsov
Entanglement distribution is a crucial problem in quantum information science, owing to the essential role that entanglement plays in enabling advanced quantum protocols, including…
Geometric monotones of violations of quantum realism
Alexandre C. Orthey, Alexander Streltsov
Quantum realism, as introduced by Bilobran and Angelo [EPL 112, 40005 (2015)], states that projective measurements in quantum systems establish the reality of physical properties,…
Certifying classes of -outcome measurements with quantum steering
Alexandre C. Orthey, Remigiusz Augusiak
Device-independent (DI) certification schemes are based on minimal assumptions about the quantum system under study, which makes the most desirable among certification schemes. How…
