Quantum State Tomography in Nonequilibrium Environments
Photonics, 2023 We generalize an approach to studying the quantum state tomography (QST) of open systems in terms of the dynamical map in Kraus representation within the framework of dynamic generation of informationally complete positive operator-valued measures.

Non-Perfect Propagation of Information to a Noisy Environment with Self-Evolution
Entropy, 2022 We study the non-perfect propagation of information for evolving a low-dimensional environment that includes self-evolution as well as noisy initial states and analyse the interrelations between the degree of objectivization and environment parameters ...

Decoherence and Ontology, or: How I Learned To Stop Worrying And Love FAPP [PDF]
, 2010 I make the case that the Universe according to unitary (no-collapse) quantum theory has a branching structure, and so can literally be regarded as a "many-worlds" theory.

The metaphysics of decoherence [PDF]
, 2021 The paper investigates the type of realism that best suits the framework of decoherence taken at face value without postulating a plurality of worlds, or additional hidden variables, or non-unitary dynamical mechanisms.

Experimental quantum decoherence control by dark states of the environment
New Journal of Physics, 2020 Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system–environment coupling can be simultaneously explored to engineer a specific dark state of the

EFT beyond the horizon:stochastic inflation and how primordial quantum fluctuations go classical [PDF]
, 2014 We identify the effective theory describing inflationary super-Hubble scales and show it to be a special case of effective field theories appropriate to open systems.

Entropy, 2017 This work investigates the influence of directional properties of decoherence on kinetics rate equations. The physical reality is understood as a chain of unitary and decoherence events.

Time-delayed quantum feedback and incomplete decoherence suppression with a no-knowledge measurement
, 2021 The no-knowledge quantum feedback was proposed by Szigeti et al. [Phys. Rev. Lett. 113, 020407 (2014)] as a measurement-based feedback protocol for decoherence suppression for an open quantum system.

Decoherence-free radio-frequency-dressed subspaces
, 2021 We study the spectral signatures and coherence properties of radio-frequency-dressed hyperfine Zeeman sublevels of Rb87. Experimentally, we engineer combinations of static and RF magnetic fields to modify the response of the atomic spin states to ...
