Experimental and theoretical characterization of a non-equilibrium steady state of a periodically driven qubit
Yong-Nan Sun, Kimmo Luoma, Zhao-Di Liu +3
Periodically driven dynamics of open quantum systems is very interesting because typically non-equilibrium steady state is reached, which is characterized by a non-vanishing curren…
Phase space theory for open quantum systems with local and collective dissipative processes
Konrad Merkel, Valentin Link, Kimmo Luoma +1
In this article we investigate driven dissipative quantum dynamics of an ensemble of two-level systems given by a Markovian master equation with collective and non-collective dissi…
Diffusive limit of non-Markovian quantum jumps
Kimmo Luoma, Walter T. Strunz, Jyrki Piilo
We solve two long standing problems for stochastic descriptions of open quantum system dynamics. First, we find the classical stochastic processes corresponding to non-Markovian qu…
Work as an external quantum observable and an operational quantum work fluctuation theorem
Konstantin Beyer, Kimmo Luoma, Walter T. Strunz
We propose a definition of externally measurable quantum work in driven systems. Work is given as a quantum observable on a control device which is forcing the system and can be de…
Continuous quantum measurement for general Gaussian unravelings can exist
Nina Megier, Walter T. Strunz, Kimmo Luoma
Quantum measurements and the associated state changes are properly described in the language of instruments. We investigate the properties of a time continuous family of instrument…
Geometry on the manifold of Gaussian quantum channels
Katarzyna Siudzińska, Kimmo Luoma, Walter T. Strunz
In the space of quantum channels, we establish the geometry that allows us to make statistical predictions about relative volumes of entanglement breaking channels among all the Ga…
