Quantum channels and memory effects

F Caruso, V Giovannetti, C Lupo, S Mancini - Reviews of Modern Physics, 2014 - APS
Any physical process can be represented as a quantum channel mapping an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …

An invitation to quantum incompatibility

T Heinosaari, T Miyadera, M Ziman - Journal of Physics A …, 2016 - iopscience.iop.org
In the context of a physical theory, two devices, A and B, described by the theory are called
incompatible if the theory does not allow the existence of a third device C that would have …

Canonical form of master equations and characterization of non-Markovianity

MJW Hall, JD Cresser, L Li, E Andersson - Physical Review A, 2014 - APS
Master equations govern the time evolution of a quantum system interacting with an
environment, and may be written in a variety of forms. Time-independent or memoryless …

Polynomially filtered exact diagonalization approach to many-body localization

P Sierant, M Lewenstein, J Zakrzewski - Physical Review Letters, 2020 - APS
Polynomially filtered exact diagonalization method (POLFED) for large sparse matrices is
introduced. The algorithm finds an optimal basis of a subspace spanned by eigenvectors …

Quantum fidelity for arbitrary Gaussian states

L Banchi, SL Braunstein, S Pirandola - Physical review letters, 2015 - APS
We derive a computable analytical formula for the quantum fidelity between two arbitrary
multimode Gaussian states which is simply expressed in terms of their first-and second …

Bounds on the capacity and power of quantum batteries

S Julià-Farré, T Salamon, A Riera, MN Bera… - Physical Review …, 2020 - APS
Quantum batteries, composed of quantum cells, are expected to outperform their classical
analogs. The origin of such advantages lies in the role of quantum correlations, which may …

Quantum circuit architecture

G Chiribella, GM D'Ariano, P Perinotti - Physical review letters, 2008 - APS
We present a method for optimizing quantum circuits architecture, based on the notion of a
quantum comb, which describes a circuit board where one can insert variable subcircuits …

An introductory review of the resource theory approach to thermodynamics

M Lostaglio - Reports on Progress in Physics, 2019 - iopscience.iop.org
I give a self-contained introduction to the resource theory approach to quantum
thermodynamics. I will introduce in an elementary manner the technical machinery …

Better late than never: information retrieval from black holes

SL Braunstein, S Pirandola, K Życzkowski - Physical review letters, 2013 - APS
We show that, in order to preserve the equivalence principle until late times in unitarily
evaporating black holes, the thermodynamic entropy of a black hole must be primarily …
