The Landauer principle states that any logically irreversible information processing must be
accompanied by dissipation into the environment. In this Letter, we investigate the heat …

Information is physical but information is also processed in finite time. Where computing
protocols are concerned, finite-time processing in the quantum regime can dynamically …

A bstract At the heart of recent progress in AdS/CFT is the question of subregion duality, or
entanglement wedge reconstruction: which part (s) of the boundary CFT are dual to a given …

Symmetry, irreversibility, and quantum coherence are foundational concepts in physics.
Here, we present a universal trade-off relation that builds a bridge between these three …

An asymmetry in thermal relaxation toward equilibrium has been uncovered for Langevin
systems near stable minima [Phys. Rev. Lett. 125, 110602 (2020) 10.1103/PhysRevLett …

Irreversibility is usually captured by a comparison between the process that happens and a
corresponding “reverse process.” In the last decades, this comparison has been extensively …

Abstract Squashed entanglement (Christandl and Winter in J. Math. Phys. 45 (3): 829–840,
2004) is a monogamous entanglement measure, which implies that highly extendible states …

In this chapter we discuss the concept of quantum Markov chains with a particular focus on
the robustness of their properties. This results in a new class of states called approximate …

We consider the thermal relaxation process of a quantum system attached to single or
multiple reservoirs. Quantifying the degree of irreversibility by entropy production, we prove …

An important issue in developing quantum technology is that quantum states are so
sensitive to noise. We propose a protocol that introduces reverse dynamics, in order to …
