Strong Local Passivity in Finite Quantum Systems
Michael Frey, Ken Funo, Masahiro Hotta
Passive states of quantum systems are states from which no system energy can be extracted by any cyclic (unitary) process. Gibbs states of all temperatures are passive. Strong loca…

Quantum Energy Teleportation between Spin Particles in a Gibbs State
Michael Frey, Karl Gerlach, Masahiro Hotta
Energy in a multipartite quantum system appears from an operational perspective to be distributed to some extent non-locally because of correlations extant among the system's compo…

Probing the qudit depolarizing channel
Michael Frey, David Collins, Karl Gerlach
For the quantum depolarizing channel with any finite dimension, we compare three schemes for channel identification: unentangled probes, probes maximally entangled with an external…
