Quantum witness of a damped qubit with generalized measurements
Manuel Bojer, Alexander Friedenberger, Eric Lutz
We evaluate the quantum witness based on the no-signaling-in-time condition of a damped two-level system for nonselective generalized measurements of varying strength. We explicitl…
Nonequilibrium information erasure below kTln2
Michael Konopik, Alexander Friedenberger, Nikolai Kiesel +1
Landauer's principle states that information erasure requires heat dissipation. Landauer's original result focused on equilibrium memories. We here investigate the reset of informa…
Tailoring the quantumness of a driven qubit
Alexander Friedenberger, Eric Lutz
We investigate the nonclassicality of a two-level system driven by an external time-dependent field in the presence of dephasing. We consider two criteria for nonclassicality, one…
