From the Unknown to the Desired: Transforming Unknown Initial States in the Resource Theory of Work and Heat
Tanmoy Biswas, Andreas Winter
We study thermodynamic state transformations in the resource theory of work and heat when the initial quantum state is unknown. Moving beyond state-dependent protocols, we develop…
Robust Quantum Key Distribution Arbitrarily Close to Local Correlations
Hari Krishnan SV, Andreas Winter
Recently, Wooltorton et al. [Phys. Rev. Lett. 132, 210802 (2024)] and Farkas [Phys. Rev. Lett. 132, 210803 (2024)] have exhibited the mismatch between Bell inequality violations an…
The geometry of absolute separability and other convex matrix properties from spectrum
Jennifer Ahiable, Naga Bhavya Teja Kothakonda, Andreas Winter
We investigate the geometric structure of the set of spectra of bipartite absolute separable states () and absolute positive partial transpose states ($\mathrm…
Playing Bayesian games better with separable quantum states than with any classical correlation
Yaqing Xy Wang, Giannicola Scarpa, Andreas Winter
Bayesian games, also known as games of incomplete information, are a fruitful arena for exploring the impact of correlations on a set of independent agents (players) via the game e…
