Collectively enhanced thermalization via multiqubit collisions

A Manatuly, W Niedenzu, R Román-Ancheyta… - Physical Review E, 2019 - APS
We investigate the evolution of a target qubit caused by its multiple random collisions with N-
qubit clusters. Depending on the cluster state, the evolution of the target qubit may …

Enhanced steady-state coherence via repeated system-bath interactions

R Román-Ancheyta, M Kolář, G Guarnieri, R Filip - Physical Review A, 2021 - APS
The appearance of steady-state coherence (SSC) from system-bath interactions proves that
quantum effects can appear without an external drive. Such SSC could become a resource …

Heat transport and rectification via quantum statistical and coherence asymmetries

S Palafox, R Román-Ancheyta, B Çakmak… - Physical Review E, 2022 - APS
Recent experiments at the nanoscales confirm that thermal rectifiers, the thermal equivalent
of electrical diodes, can operate in the quantum regime. We present a thorough investigation …

Heat flow reversals without reversing the arrow of time: The role of internal quantum coherences and correlations

CL Latune, I Sinayskiy, F Petruccione - Physical Review Research, 2019 - APS
One of the stunning consequences of quantum correlations in thermodynamics is the
reversal of the arrow of time, recently shown experimentally in Micadei et al.[Nat. Commun …

Spectral signatures of non-thermal baths in quantum thermalization

R Román-Ancheyta, B Çakmak… - Quantum Science …, 2019 - iopscience.iop.org
We show that certain coherences, termed as heat-exchange coherences, which contribute to
the thermalization process of a quantum probe in a repeated interactions scheme, can …

[HTML][HTML] Transfer of quantum information via a dissipative protocol for data classification

U Korkmaz, D Türkpençe - Physics Letters A, 2022 - Elsevier
We consider the equilibration dynamics of a two-level quantum system in contact with
multiple structured reservoirs that carry quantum information. We develop a micromaser-like …

[HTML][HTML] A steady state quantum classifier

D Türkpençe, TÇ Akıncı, S Şeker - Physics Letters A, 2019 - Elsevier
We report that under some specific conditions a single qubit model weakly interacting with
information environments can be referred to as a quantum classifier. We exploit the additivity …

Mimicking an information reservoir by superconducting quantum circuits
