Cavity Mode Frequencies and Strong Optomechanical Coupling in Two-Membrane Cavity Optomechanics
J. Li, A. Xuereb, N. Malossi +1
We study the cavity mode frequencies of a Fabry-Pérot cavity containing two vibrating dielectric membranes. We derive the equations for the mode resonances and provide approximate…
Non-Markovian quantum processes: complete framework and efficient characterisation
Felix A. Pollock, César Rodríguez-Rosario, Thomas Frauenheim +2
Currently, there is no systematic way to describe a quantum process with memory solely in terms of experimentally accessible quantities. However, recent technological advances mean…
Private algebras in quantum information and infinite-dimensional complementarity
Jason Crann, David W. Kribs, Rupert H. Levene +1
We introduce a generalized framework for private quantum codes using von Neumann algebras and the structure of commutants. This leads naturally to a more general notion of compleme…
Divisible quantum dynamics satisfies temporal Tsirelson's bound
Thao Le, Felix A. Pollock, Tomasz Paterek +2
We give strong evidence that divisibility of qubit quantum processes implies temporal Tsirelson's bound. We also give strong evidence that the classical bound of the temporal Bell'…
Quantum-state transfer in staggered coupled-cavity arrays
Guilherme M. A. Almeida, Francesco Ciccarello, Tony J. G. Apollaro +1
We consider a coupled-cavity array, where each cavity interacts with an atom under the rotating-wave approximation. For a staggered pattern of inter-cavity couplings, a pair of fie…
Thermodynamics of trajectories and local fluctuation theorems for harmonic quantum networks
Simon Pigeon, Lorenzo Fusco, André Xuereb +2
We present a general method to undertake a thorough analysis of the thermodynamics of the quantum jump trajectories followed by an arbitrary quantum harmonic network undergoing lin…
Perspective: Quantum Thermodynamics
James Millen, André Xuereb
Classical thermodynamics is unrivalled in its range of applications and relevance to everyday life. It enables a description of complex systems, made up of microscopic particles, i…
Coherent manipulation of noise-protected superconducting artificial atoms in the Lambda scheme
P. G. Di Stefano, E. Paladino, T. J. Pope +1
We propose a new protocol for thr manipulation of a three-level artificial atom in Lambda () configuration in the absence of a direct pump coupling. It allows faithful, selectiv…
Cost of counterdiabatic driving and work output
Yuanjian Zheng, Steve Campbell, Gabriele De Chiara +1
Unitary processes allow for the transfer of work to and from Hamiltonian systems. However, to achieve nonzero power for the practical extraction of work, these processes must be pe…
Generation of cluster states in optomechanical quantum systems
O. Houhou, H. Aissaoui, A. Ferraro
We consider an optomechanical quantum system composed of a single cavity mode interacting with N mechanical resonators. We propose a scheme for generating continuous-variable graph…
Violation of Bell inequalities in larger Hilbert spaces: robustness and challenges
Werner Weiss, Giuliano Benenti, Giulio Casati +4
We explore the challenges posed by the violation of Bell-like inequalities by -dimensional systems exposed to imperfect state-preparation and measurement settings. We address, i…
Nonlinearity as a resource for nonclassicality in anharmonic systems
F. Albarelli, A. Ferraro, M. Paternostro +1
Nonclassicality is a key ingredient for quantum enhanced technologies and experiments involving macro- scopic quantum coherence. Considering various exactly-solvable quantum-oscill…
Equilibration and nonclassicality of a double-well potential
Steve Campbell, Gabriele De Chiara, Mauro Paternostro
A double well loaded with bosonic atoms represents an ideal candidate to simulate some of the most interesting aspects in the phenomenology of thermalisation and equilibration. Her…
Testing Wavefunction Collapse Models using Parametric Heating of a Trapped Nanosphere
Daniel Goldwater, Mauro Paternostro, P. F. Barker
We propose a mechanism for testing the theory of collapse models such as continuous spontaneous localization (CSL) by examining the parametric heating rate of a trapped nanosphere.…
Nonclassicality and criticality in symmetry-protected magnetic phases
Matthew J. M. Power, Steve Campbell, Maria Moreno-Cardoner +1
Quantum and global discord in a spin-1 Heisenberg chain subject to single-ion anisotropy (uniaxial field) are studied using exact diagonalisation and the density matrix renormalisa…
Macroscopic quantum resonators (MAQRO): 2015 Update
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +49
Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrödinger's cat paradox - or do gravitation or yet unknown effects set a limit for mas…
Landauer's principle in multipartite open quantum system dynamics
S. Lorenzo, R. McCloskey, F. Ciccarello +2
We investigate the link between information and thermodynamics embodied by Landauer's principle in the open dynamics of a multipartite quantum system. Such irreversible dynamics is…
Enabling entanglement distillation via optomechanics
Victor Montenegro, Alessandro Ferraro, Sougato Bose
Quantum networking based on optical Gaussian states, although promising in terms of scalability, is hindered by the fact that their entanglement cannot be distilled via Gaussian op…
Single- and two-mode quantumness at a beam splitter
Matteo Brunelli, Claudia Benedetti, Stefano Olivares +2
In the context of bipartite bosonic systems, two notions of classicality of correlations can be defined: P-classicality, based on the properties of the Glauber-Sudarshan P-function…
Transfer of arbitrary two qubit states via a spin chain
S. Lorenzo, T. J. G. Apollaro, S. Paganelli +2
We investigate the fidelity of the quantum state transfer (QST) of two qubits by means of an arbitrary spin-1/2 network, on a lattice of any dimensionality. Under the assumptions t…
Irreversibility and the arrow of time in a quenched quantum system
T. B. Batalhao, A. M. Souza, R. S. Sarthour +4
Irreversibility is one of the most intriguing concepts in physics. While microscopic physical laws are perfectly reversible, macroscopic average behavior has a preferred direction…
Nonlinearity and nonclassicality in a nanomechanical resonator
Berihu Teklu, Alessandro Ferraro, Mauro Paternostro +1
We address quantitatively the relationship between the nonlinearity of a mechanical resonator and the nonclassicality of its ground state. In particular, we analyze the nonclassica…
