Minimal covariant observables identifying all pure states

Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo

It has been recently shown that an observable that identifies all pure states of a d-dimensional quantum system has minimally 4d-4 outcomes or slightly less (the exact number depen…

Signatures of non-Markovianity in classical single-time probability distributions

Andrea Smirne, Alberto Stabile, Bassano Vacchini

We show that the Kolmogorov distance allows to quantify memory effects in classical stochastic processes by studying the evolution of the single-time probability distribution. We f…

Hidden entanglement in the presence of random telegraph dephasing noise

A. D'Arrigo, R. Lo Franco, G. Benenti +2

Entanglement dynamics of two noninteracting qubits, locally affected by random telegraph noise at pure dephasing, exhibits revivals. These revivals are not due to the action of any…

Discording power of quantum evolutions

F. Galve, F. Plastina, M. G. A. Paris +1

We introduce the discording power of a unitary transformation, which assesses its capability to produce quantum discord, and analyze in detail the generation of discord by relevant…

Quantum interference induced by initial system-environment correlations

Zhong-Xiao Man, Andrea Smirne, Yun-Jie Xia +1

We investigate the quantum interference induced by a relative phase in the correlated initial state of a system which consists in a two-level atom interacting with a damped mode of…

A classical appraisal of quantum definitions of non-Markovian dynamics

Bassano Vacchini

We consider the issue of non-Markovianity of a quantum dynamics starting from a comparison with the classical definition of Markovian process. We point to the fact that two suffici…

Recovering Entanglement by Local Operations

A. D'Arrigo, R. Lo Franco, G. Benenti +2

We investigate the phenomenon of bipartite entanglement revivals under purely local operations in systems subject to local and independent classical noise sources. We explain this…

The driven Harper model

Andrey R. Kolovsky, Giorgio Mantica

We analyze the driven Harper model, which appears in the problem of tight-binding electrons in the Hall configuration (normal to the lattice plane magnetic field plus in-plane elec…

Cyclotron-Bloch dynamics of a quantum particle in a two-dimensional lattice II

A. R. Kolovsky, I. Chesnokov, G. Mantica

We study the quantum dynamics of a charged particle in a two-dimensional lattice, subject to constant and homogeneous electric and magnetic fields. We find that different regimes c…

Entanglement in helium

Giuliano Benenti, Stefano Siccardi, Giuliano Strini

Using a configuration-interaction variational method, we accurately compute the reduced, single-electron von Neumann entropy for several low-energy, singlet and triplet eigenstates…

Scaling behavior for a class of quantum phase transitions

Wen-ge Wang, Pinquan Qin, Qian Wang +2

We show that for quantum phase transitions with a single bosonic zero mode at the critical point, like the Dicke model and the Lipkin-Meshkov-Glick model, metric quantities such as…

Critical assessment of two-qubit post-Markovian master equations

S. Campbell, A. Smirne, L. Mazzola +4

A post-Markovian master equation has been recently proposed as a tool to describe the evolution of a system coupled to a memory-keeping environment [A. Shabani and D. A. Lidar, Phy…

Optical interferometry in the presence of large phase diffusion

Marco G. Genoni, Stefano Olivares, Davide Brivio +5

Phase diffusion represents a crucial obstacle towards the implementation of high precision interferometric measurements and phase shift based communication channels. Here we presen…

Emission of correlated photon pairs from superluminal perturbations in dispersive media

Francesco Dalla Piazza, Francesco Belgiorno, Sergio Luigi Cacciatori +1

We develop a perturbative theory that describes a superluminal refractive perturbation propagating in a dispersive medium and the subsequent excitation of the quantum vacuum zero-p…

Wigner separability entropy and complexity of quantum dynamics

Giuliano Benenti, Gabriel G. Carlo, Tomaz Prosen

We propose the Wigner separability entropy as a measure of complexity of a quantum state. This quantity measures the number of terms that effectively contribute to the Schmidt deco…
