Thermodynamics of information processing in small systems

T Sagawa - Progress of theoretical physics, 2012 - academic.oup.com
We review a general theory of thermodynamics of information processing. The background
of this topic is the recently-developed nonequilibrium statistical mechanics and quantum …

Generation of two-giant-atom entanglement in waveguide-QED systems

XL Yin, JQ Liao - Physical Review A, 2023 - APS
We study the generation of quantum entanglement between two giant atoms coupled to a
one-dimensional waveguide. Since each giant atom interacts with the waveguide at two …

L Aolita, F De Melo, L Davidovich - Reports on Progress in …, 2015 - iopscience.iop.org
One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Generalized Jarzynski equality under nonequilibrium feedback control

T Sagawa, M Ueda - Physical review letters, 2010 - APS
The Jarzynski equality is generalized to situations in which nonequilibrium systems are
subject to a feedback control. The new terms that arise as a consequence of the feedback …

Non-Markovian dynamics of quantum discord

FF Fanchini, T Werlang, CA Brasil, LGE Arruda… - Physical Review A …, 2010 - APS
We evaluate the quantum discord dynamics of two qubits in independent and common non-
Markovian environments. We compare the dynamics of entanglement with that of quantum …

Fluctuation Theorem with Information Exchange: Role of Correlations<? format?> in Stochastic Thermodynamics

T Sagawa, M Ueda - Physical review letters, 2012 - APS
We establish the fluctuation theorem in the presence of information exchange between a
nonequilibrium system and other degrees of freedom such as an observer and a feedback …

Dynamics of quantum correlations in two-qubit systems within non-Markovian environments

RL Franco, B Bellomo, S Maniscalco… - International Journal of …, 2013 - World Scientific
Knowledge of the dynamical behavior of correlations with no classical counterpart, like
entanglement, nonlocal correlations and quantum discord, in open quantum systems is of …

Nonequilibrium thermodynamics of feedback control

T Sagawa, M Ueda - Physical Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
We establish a general theory of feedback control on classical stochastic thermodynamic
systems and generalize nonequilibrium equalities such as the fluctuation theorem and the …

Non-Markovian effect on the quantum discord

We study the non-Markovian effect on the dynamics of the quantum discord by exactly
solving a model consisting of two independent qubits subject to two zero-temperature non …

Sudden death and sudden birth of entanglement in common structured reservoirs

L Mazzola, S Maniscalco, J Piilo, KA Suominen… - Physical Review A …, 2009 - APS
We study the exact entanglement dynamics of two qubits in a common structured reservoir.
We demonstrate that for certain classes of entangled states, entanglement sudden death …
