Quantifying non-Markovianity due to driving and a finite-size environment in an open quantum system
Rui Sampaio, Samu Suomela, Rebecca Schmidt +1
We study non-Markovian effects present in a driven qubit coupled to a finite environment using a recently proposed model developed in the context of calorimetric measurements of op…
Quantum Control in Qutrit Systems using Hybrid Rabi-STIRAP Pulses
Antti Vepsäläinen, Sergey Danilin, Elisabetta Paladino +2
We introduce and analyze theoretically a procedure that combines slow adiabatic STIRAP manipulation with short nonadiabatic Rabi pulses to produce any desired three-level state in…
Generalized noise terms for the quantized fluctuational electrodynamics
Mikko Partanen, Teppo Häyrynen, Jani Oksanen +1
The quantization of optical fields in vacuum has been known for decades, but extending the field quantization to lossy and dispersive media in nonequilibrium conditions has proven…
Energy backflow in strongly coupled non-Markovian continuous-variables systems
Giacomo Guarnieri, Johannes Nokkala, Rebecca Schmidt +2
By employing the full counting statistics formalism, we characterize the first moment of energy that is exchanged during a generally non-Markovian evolution in non-driven continuou…
Detecting non-Markovianity of quantum evolution via spectra of dynamical maps
Dariusz Chruściński, Chiara Macchiavello, Sabrina Maniscalco
We provide an analysis on non-Markovian quantum evolution based on the spectral properties of dynamical maps. We introduce the dynamical analog of entanglement witness to detect no…
Comparison between quantum jumps and master equation in the presence of a finite environment
Samu Suomela, Rui Sampaio, Tapio Ala-Nissila
We study the equivalence between the recently proposed finite environment quantum jump model and a master equation approach. We derive microscopically the master equation for a qub…
