Modeling dissipation in quantum active matter
Alexander P. Antonov, Sangyun Lee, Benno Liebchen +5
Active matter is characterized by a constant influx and dissipation of energy that gives rise to directed motion. Dissipation requires interactions with an external environment, su…
Robust certification of non-projective measurements: theory and experiment
Raphael Brinster, Peter Tirler, Shishir Khandelwal +7
Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…
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…
Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…
Maximally non-projective measurements are not always symmetric informationally complete
Gabriele Cobucci, Raphael Brinster, Shishir Khandelwal +4
Standard quantum measurements are projective. However, the full scope of quantum measurements is represented by positive operator-valued measures (POVMs) and many of these break th…
Spanning-tree-packing protocol for conference key propagation in quantum networks
Anton Trushechkin, Hermann Kampermann, Dagmar Bruß
We consider a network of users connected by pairwise quantum key distribution (QKD) links. Using these pairwise secret keys and public classical communication, the users want to ge…
