Squeezing of mechanical motion via qubit-assisted control
Marco G. Genoni, Matteo Bina, Stefano Olivares +2
We propose a feedback control mechanism for the squeezing of the phononic mode of a mechanical oscillator. We show how, under appropriate working conditions, a simple adiabatic app…
Experimental reconstruction of work distribution and verification of fluctuation relations at the full quantum level
Tiago Batalhão, Alexandre M. Souza, Laura Mazzola +6
Research on the out-of-equilibrium dynamics of quantum systems has so far produced important statements on the thermodynamics of small systems undergoing quantum mechanical evoluti…
Dynamical symmetry breaking with optimal control: reducing the number of pieces
Matthew J. M. Power, Gabriele De Chiara
We analyse the production of defects during the dynamical crossing of a mean-field phase transition with a real order parameter. When the parameter that brings the system across th…
Long-range multipartite entanglement close to a first order quantum phase transition
Julia Stasińska, Benjamin Rogers, Mauro Paternostro +2
We provide insight in the quantum correlations structure present in strongly correlated systems beyond the standard framework of bipartite entanglement. To this aim we first exploi…
Scaling of the entanglement spectrum near quantum phase transitions
L. Lepori, G. De Chiara, A. Sanpera
The entanglement spectrum describing quantum correlations in many-body systems has been recently recognized as a key tool to characterize different quantum phases, including topolo…
Non-Markovian qubit dynamics induced by Coulomb crystals
Massimo Borrelli, Pinja Haikka, Gabriele De Chiara +1
We investigate the back-flow of information in a system with a second-order structural phase transition, namely a quasi one-dimensional Coulomb crystal. Using standard Ramsey inter…
Full characterization of the quantum linear-zigzag transition in atomic chains
Pietro Silvi, Gabriele De Chiara, Tommaso Calarco +2
A string of repulsively interacting particles exhibits a phase transition to a zigzag structure, by reducing the transverse trap potential or the interparticle distance. The transi…
Measuring the characteristic function of the work distribution
Laura Mazzola, Gabriele De Chiara, Mauro Paternostro
We propose an interferometric setting for the ancilla-assisted measurement of the characteristic function of the work distribution following a time-dependent process experienced by…
Violation of Bell's inequalities with pre-amplified homodyne detection
G. Torlai, G. McKeown, P. Marek +4
We show that the use of probabilistic noiseless amplification in entangled coherent state-based schemes for the test of quantum non locality provides substantial advantages. The th…
