Quantum coherence as a signature of chaos
Namit Anand, Georgios Styliaris, Meenu Kumari +1
We establish a rigorous connection between quantum coherence and quantum chaos by employing coherence measures originating from the resource theory framework as a diagnostic tool f…
Information Scrambling over Bipartitions: Equilibration, Entropy Production, and Typicality
Georgios Styliaris, Namit Anand, Paolo Zanardi
In recent years, the out-of-time-order correlator (OTOC) has emerged as a diagnostic tool for information scrambling in quantum many-body systems. Here, we present exact analytical…
Symmetries and monotones in Markovian quantum dynamics
Georgios Styliaris, Paolo Zanardi
What can one infer about the dynamical evolution of quantum systems just by symmetry considerations? For Markovian dynamics in finite dimensions, we present a simple construction t…
Quantum coherence and the localization transition
Georgios Styliaris, Namit Anand, Lorenzo Campos Venuti +1
A dynamical signature of localization in quantum systems is the absence of transport which is governed by the amount of coherence that configuration space states possess with respe…
Fundamental limitations to local energy extraction in quantum systems
Álvaro M. Alhambra, Georgios Styliaris, Nayeli A. Rodriguez-Briones +2
We examine when it is possible to locally extract energy from a bipartite quantum system in the presence of strong coupling and entanglement, a task which is expected to be restric…
Quantifying the incompatibility of quantum measurements relative to a basis
Georgios Styliaris, Paolo Zanardi
Motivated by quantum resource theories, we introduce a notion of incompatibility for quantum measurements relative to a reference basis. The notion arises by considering states dia…
Mixing of quantum states under Markovian dissipation and coherent control
Georgios Styliaris, Álvaro M. Alhambra, Paolo Zanardi
Given any two quantum states and in Hilbert spaces of equal dimension satisfying the majorization condition , it is always possible to transform by a…
Coherence generating power of quantum dephasing processes
Georgios Styliaris, Lorenzo Campos Venuti, Paolo Zanardi
We provide a quantification of the capability of various quantum dephasing processes to generate coherence out of incoherent states. The measures defined, admitting computable expr…
Measures of coherence generating power for quantum unital operations
Paolo Zanardi, Georgios Styliaris, Lorenzo Campos Venuti
Given an orthonormal basis in a -dimensional Hilbert space and a unital quantum operation acting on it one can define a non-linear mapping that associates to a…
Coherence generating power of quantum unitary maps and beyond
Paolo Zanardi, Georgios Styliaris, Lorenzo Campos Venuti
Given a preferred orthonormal basis in the Hilbert space of a quantum system we define a measure of the coherence generating power of a unitary operation with respect to . T…
