Experimental linear-optics simulation of the ground state of an interacting quantum spin-ring
Adeline Orieux, Joelle Boutari, Marco Barbieri +2
Critical phenomena involve a structural change in the correlations of its constituents. These features can be employed in quantum simulators to assess when a criticality occurred i…
Reconfigurable long-range phonon dynamics in optomechanical arrays
André Xuereb, Claudiu Genes, Guido Pupillo +2
We investigate periodic optomechanical arrays as reconfigurable platforms for engineering the coupling between multiple mechanical and electromagnetic modes and for exploring many-…
Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Localization-like effect in two-dimensional alternate quantum walks with periodic coin operations
Carlo Di Franco, Mauro Paternostro
Exploiting multi-dimensional quantum walks as feasible platforms for quantum computation and quantum simulation is attracting constantly growing attention from a broad experimental…
Master equation for dissipative interacting qubits in a common environment
J. P. Santos, F. L. Semião
In this paper, we derive a microscopic master equation for a pair of XY-coupled two-level systems interacting with the same memoryless reservoir. In particular, we apply this maste…
Experimental realisation of a delayed-choice quantum walk
Youn-Chang Jeong, Carlo Di Franco, Hyang-Tag Lim +2
Many paradoxes of quantum mechanics come from the fact that a quantum system can possess different features at the same time, such as in wave-particle duality or quantum superposit…
Non-classicality of optomechanical devices in experimentally realistic operating regimes
G. Vacanti, M. Paternostro, G. M. Palma +2
Enforcing a non-classical behavior in mesoscopic systems is important for the study of the boundaries between quantum and classical world. Recent experiments have shown that optome…
Effective cutting of a quantum spin chain by bond impurities
T. J. G. Apollaro, F. Plastina, L. Banchi +4
Spin chains are promising media for short-haul quantum communication. Their usefulness is manifested in all those situations where stationary information carriers are involved. In…
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 Demonstration of non-Markovian Dynamics via a Temporal Bell-like Inequality
A. M. Souza, J. Li, D. O. Soares-Pinto +5
We assess non-Markovianity of a quantum open-system dynamics through the violation of temporal bell-like inequalities in a controllable Nuclear Magnetic Resonance system. We invest…
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…
Coherently opening a high-Q cavity
Tommaso Tufarelli, Alessandro Ferraro, Alessio Serafini +2
We propose a general framework to effectively `open' a high-Q resonator, that is, to release the quantum state initially prepared in it in the form of a traveling electromagnetic w…
Optomechanical interface for probing matter-wave coherence
André Xuereb, Hendrik Ulbricht, Mauro Paternostro
We combine matter-wave interferometry and cavity optomechanics to propose a coherent matter--light interface based on mechanical motion at the quantum level. We demonstrate a mecha…
Measurement-induced generation of spatial entanglement in a two-dimensional quantum walk with single-qubit coin
C. Di Franco, M. Mc Gettrick, T. Machida +1
One of the proposals for the exploitation of two-dimensional quantum walks has been the efficient generation of entanglement. Unfortunately, the technological effort required for t…
Superadiabatic dynamics in open quantum systems
G. Vacanti, R. Fazio, S. Montangero +3
We extend the concept of superadiabatic dynamics, or transitionless quantum driving, to quantum open systems whose evolution is governed by a master equation in the Lindblad form.…
More bang for your buck: Towards super-adiabatic quantum engines
A. del Campo, J. Goold, M. Paternostro
The reversible nature of thermodynamical cycles is an idealisation based on the assumption of perfect quasi-static dynamics. As a consequence of this assumption, ideal engines oper…
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…
Collectively-enhanced optomechanical coupling in periodic arrays of scatterers
André Xuereb, Claudiu Genes, Aurélien Dantan
We investigate the optomechanical properties of a periodic array of identical scatterers placed inside an optical cavity and extend the results of [A. Xuereb, C. Genes, and A. Dant…
Enhanced optomechanical readout using optical coalescence
Claudiu Genes, André Xuereb, Guido Pupillo +1
We present a scheme to strongly enhance the readout sensitivity of the squared displacement of a mobile scatterer placed in a Fabry-Pérot cavity. We investigate the largely unexplo…
Glued trees algorithm under phase damping
J. Lockhart, C. Di Franco, M. Paternostro
We study the behaviour of the glued trees algorithm described by Childs et al. in [STOC `03, Proc. 35th ACM Symposium on Theory of Computing (2004) 59] under decoherence. We consid…
Experimental distribution of entanglement with separable carriers
A. Fedrizzi, M. Zuppardo, G. G. Gillett +5
The key requirement for quantum networking is the distribution of entanglement between nodes. Surprisingly, entanglement can be generated across a network without direct transfer -…
Geometrical characterization of non-Markovianity
S. Lorenzo, F. Plastina, M. Paternostro
We introduce a new tool for the quantitative characterisation of the departure form Markovianity of a given dynamical process. Our tool can be applied to a generic -level system…
Interaction-induced correlations and non-Markovianity of quantum dynamics
Andrea Smirne, Laura Mazzola, Mauro Paternostro +1
We investigate the conditions under which the trace distance between two different states of a given open system increases in time due to the interaction with an environment, there…
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…
