Selectable linear or quadratic coupling in an optomechanical system
André Xuereb, Mauro Paternostro
There has been much interest recently in the analysis of optomechanical systems incorporating dielectric nano- or microspheres inside a cavity field. We analyse here the situation…
A no-go result on the purification of quantum states
C. Di Franco, M. Paternostro
The information encoded in a quantum system is generally spoiled by the influences of its environment, leading to a transition from pure to mixed states. Reducing the mixedness of…
Phase-space behavior and conditional dynamics of an optomechanical system
S. Groeblacher, S. Gigan, M. Paternostro
We characterize the local properties of an optomechanical system comprising the movable mirror of a resonator and its intracavity field, mutually coupled via radiation-pressure. Ou…
Testing genuine multipartite nonlocality in phase space
Seung-Woo Lee, Mauro Paternostro, Jinhyoung Lee +1
We demonstrate genuine three-mode nonlocality based on phase space formalism. A Svetlichny-type Bell inequality is formulated in terms of the -parameterized quasiprobability fun…
Enhancing non-classicality in mechanical systems
Jie Li, Simon Groeblacher, Mauro Paternostro
We study the effects of post-selection measurements on both the non-classicality of the state of a mechanical oscillator and the entanglement between two mechanical systems that ar…
Tomographic characterisation of correlations in a photonic tripartite state
A. Chiuri, L. Mazzola, M. Paternostro +1
Starting from a four-partite photonic hyper-entangled Dicke resource, we report the full tomographic characterization of three-, two-, and one-qubit states obtained by projecting o…
Linear Optics Simulation of Non-Markovian Quantum Dynamics
Andrea Chiuri, Chiara Greganti, Laura Mazzola +2
The simulation of quantum processes is a key goal for the grand programme aiming at grounding quantum technologies as the way to explore complex phenomena that are inaccessible thr…
Entanglement control via reservoir engineering in ultracold atomic gases
Suzanne McEndoo, Pinja Haikka, Gabriele de Chiara +2
We study the entanglement of two impurity qubits immersed in a Bose-Einstein condensate (BEC) reservoir. This open quantum system is particularly interesting because the reservoir…
N-dimensional alternate coined quantum walks from a dispersion relation perspective
Eugenio Roldán, Carlo Di Franco, Fernando Silva +1
We propose an alternative definition of an N-dimensional coined quantum walk by generalizing a recent proposal [Di Franco et al., Phys. Rev. Lett. 106, 080502 (2011)]. This N-dimen…
Transferring entanglement to the steady-state of flying qubits
Yanqiang Guo, Jie Li, Tiancai Zhang +1
The transfer of entanglement from optical fields to qubits provides a viable approach to entangling remote qubits in a quantum network. In cavity quantum electrodynamics, the schem…
Exciton-mediated photothermal cooling in GaAs membranes
André Xuereb, Koji Usami, Andreas Naesby +2
Cooling of the mechanical motion of a GaAs nano-membrane using the photothermal effect mediated by excitons was recently demonstrated by some of us [K. Usami, et al., Nature Phys.…
Qubit-assisted thermometry of a quantum harmonic oscillator
Matteo Brunelli, Stefano Olivares, Mauro Paternostro +1
We use the theory of quantum estimation in two different qubit-boson coupling models to demonstrate that the temperature of a quantum harmonic oscillator can be estimated with high…
Tuning non-Markovianity by spin-dynamics control
Salvatore Lorenzo, Francesco Plastina, Mauro Paternostro
We study the interplay between forgetful and memory-keeping evolution enforced on a two-level system by a multi-spin environment whose elements are coupled to local bosonic baths.…
Robust non-Markovianity in ultracold gases
Pinja Haikka, Suzanne McEndoo, Gabriele De Chiara +2
We study the effect of thermal fluctuations on a probe qubit interacting with a Bose-Einstein condensed (BEC) reservoir. The zero-temperature case was studied in [Haikka P et al 20…
Multipartite optomechanical entanglement from competing nonlinearities
André Xuereb, Marco Barbieri, Mauro Paternostro
We investigate the nature of the three-mode interaction inside an optomechanically-active microtoroid with a sizeable chi^(2) coefficient. Experimental techniques are quickly advan…
Dynamical scattering models in optomechanics: Going beyond the 'coupled cavities' model
André Xuereb, Peter Domokos
Recently [A. Xuereb, et al., Phys. Rev. Lett. 105, 013602 (2010)], we calculated the radiation field and the optical forces acting on a moving object inside a general one-dimension…
Unification of witnessing initial system-environment correlations and witnessing non-Markovianity
César A. Rodríguez-Rosario, Kavan Modi, Laura Mazzola +1
We show the connection between a witness that detects dynamical maps with initial system-environment correlations and a witness that detects non-Markovian open quantum systems. Our…
Entanglement replication in driven-dissipative many body systems
S. Zippilli, M. Paternostro, G. Adesso +1
We study the dissipative dynamics of two independent arrays of many-body systems, locally driven by a common entangled field. We show that in the steady state the entanglement of t…
Entanglement control in hybrid optomechanical systems
B. Rogers, M. Paternostro, G. M. Palma +1
We demonstrate the control of entanglement in a hybrid optomechanical system comprising an optical cavity with a mechanical end-mirror and an intracavity Bose-Einstein condensate (…
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…
Dynamical role of system-environment correlations in non-Markovian dynamics
Laura Mazzola, Cesar A. Rodrıguez-Rosario, Kavan Modi +1
We analyse the role played by system-environment correlations in the emergence of non-Markovian dynamics. By working within the framework developed in Breuer et al., Phys. Rev. Let…
Quantum discord bounds the amount of distributed entanglement
T. K. Chuan, J. Maillard, K. Modi +3
The ability to distribute quantum entanglement is a prerequisite for many fundamental tests of quantum theory and numerous quantum information protocols. Two distant parties can in…
