Quantum simulation of bosonic-fermionic non-interacting particles in disordered systems via quantum walk
Francesco De Nicola, Linda Sansoni, Andrea Crespi +6
We report on the theoretical analysis of bosonic and fermionic non-interacting systems in a discrete two-particle quantum walk affected by different kinds of disorder. We considere…
Speeding up and slowing down the relaxation of a qubit by optimal control
Victor Mukherjee, Alberto Carlini, Andrea Mari +5
We consider a two-level quantum system prepared in an arbitrary initial state and relaxing to a steady state due to the action of a Markovian dissipative channel. We study how opti…
Steady-state entanglement activation in optomechanical cavities
Alessandro Farace, Francesco Ciccarello, Rosario Fazio +1
Quantum discord, and a number of related indicators, are currently raising a relentless interest as a novel paradigm of non-classical correlations beyond entanglement. Beside merel…
Photon transfer in ultrastrongly coupled three-cavity arrays
S. Felicetti, G. Romero, D. Rossini +2
We study the photon transfer along a linear array of three coupled cavities where the central one contains an interacting two-level system in the strong and ultrastrong coupling re…
Anderson localization of entangled photons in an integrated quantum walk
Andrea Crespi, Roberto Osellame, Roberta Ramponi +5
Waves fail to propagate in random media. First predicted for quantum particles in the presence of a disordered potential, Anderson localization has been observed also in classical…
Extracting quantum work statistics and fluctuation theorems by single qubit interferometry
R. Dorner, S. R. Clark, L. Heaney +3
We propose an experimental scheme to verify the quantum non-equilibrium fluctuation relations using current technology. Specifically, we show that the characteristic function of th…
Photon solid phases in driven arrays of nonlinearly coupled cavities
Jiasen Jin, Davide Rossini, Rosario Fazio +2
We introduce and study the properties of an array of QED cavities coupled by nonlinear elements, in the presence of photon leakage and driven by a coherent source. The nonlinear co…
