We examine non-Markovian effects in an open quantum system
from the point of view of information flow. To this end, we
consider the spin-boson model with a cold reservoir,
accounting for the exact time-dependent correlations between
the system and the bath to study the exchange of information
and heat. We use an information theoretic measure of the
relevant memory effects and demonstrate...

The state of a quantum system is described by a wavefunction
evolving in time according to the Schroedinger equation. If
a measurement is carried out on the system, its wave
function collapses, i.e., it changes according to the random
outcome of the measurement. During a sequence of
measurements on a single system, its quantum state thus
follows a stochastic trajectory composed of the...

I will present a photonics experiment that can be understood
as an example of Maxwell’s demon. In this experiment we
showed that a measurement at the few-photons level performed
on intense thermal light modes allows, by employing an
operation conditional on measurement outcomes, the creation
of an intensity unbalance, which we used to extract
measurable work into an electric circuit. In...
