Accurate "superluminal" transmission via entanglement, superoscillations and quasi-Dirac distributions
D. Sokolovski, R. Sala Mayato
We analyse a system in which, due to entanglement between the spin and spatial degrees of freedom, the reduced transmitted state has the shape of the freely propagating pulse trans…
Quantum state transfer via temporal kicking of information
C. Di Franco, M. Paternostro, M. S. Kim
We propose a strategy for perfect state transfer in spin chains based on the use of an unmodulated coupling Hamiltonian whose coefficients are explicitly time dependent. We show th…
Emergence of canonical ensembles from pure quantum states
Jaeyoon Cho, M. S. Kim
We consider a system weakly interacting with a bath as a thermodynamic setting to establish a quantum foundation of statistical physics. It is shown that even if the composite syst…
Experimental demonstration of bosonic commutation relation via superpositions of quantum operations on thermal light fields
A. Zavatta, V. Parigi, M. S. Kim +2
We present the experimental realization of a scheme, based on single-photon interference, for implementing superpositions of distinct quantum operations. Its application to a therm…
Reducing quantum control for spin-spin entanglement distribution
Francesco Ciccarello, Mauro Paternostro, G. Massimo Palma +1
We present a protocol that sets maximum stationary entanglement between remote spins through scattering of mobile mediators without initialization, post-selection or feedback of th…
Testing non-local realism with entangled coherent states
M. Paternostro, H. Jeong
We investigate the violation of non-local realism using entangled coherent states (ECS) under nonlinear operations and homodyne measurements. We address recently proposed Leggett-t…
Passing quantum correlations to qubits using any two-mode state
Mauro Paternostro, Gerardo Adesso, Steve Campbell
We draw an explicit connection between the statistical properties of an entangled two-mode continuous variable (CV) resource and the amount of entanglement that can be dynamically…
Qubit Mediated Time Robust Entangling of Oscillators in Thermal Environments
Tommaso Tufarelli, M. S. Kim, Sougato Bose
We consider two separated oscillators initially in equilibrium and continuously interacting with thermal environments, and propose a way to entangle them using a mediating qubit. A…
Conditions for Factorizable Output From a Beam splitter
S. C. Springer, Jinhyoung Lee, M. Bellini +1
A beam splitter is one of the most important devices in an optics laboratory because of its handiness and versatility; equivalent devices are found in various quantum systems to co…
Entanglement accumulation, retrieval, and concentration in cavity QED
Daniel Ballester
The ability to accumulate and retrieve entanglement in the fields of two remote cavities with pairs of two-level atoms is discussed. It is shown that this transfer and retrieval ca…
Weak values, 'negative probability' and the uncertainty principle
D. Sokolovski
A quantum transition can be seen as a result of interference between various pathways(e.g. Feynman paths) which can be labelled by a variable . An attempt to determine the value…
Teleportation protocol with non-ideal conditional local operations
C. Di Franco, D. Ballester
In the standard protocol for quantum teleportation, one assumes that Bob is able to perform ideal operations on his qubit. Here, we analyze the case in which some of these operatio…
Teleporting bipartite entanglement using maximally entangled mixed channels
S. Campbell, M. Paternostro
The ability to teleport entanglement through maximally entangled mixed states as defined by concurrence and linear entropy is studied. We show how the teleported entanglement depen…
Mirror-mediated cooling: a paradigm for particle cooling via the retarded dipole force
Tim Freegarde, James Bateman, André Xuereb +1
Cooling forces result from the retarded dipole interaction between an illuminated particle and its reflection. For a one-dimensional example, we find cooling times of milliseconds…
Feynman-path analysis of Hardy's paradox: measurements and the uncertainty principle
D. Sokolovski, I. Puerto Gimenez, R. Sala Mayato
Hardy's paradox is analysed within Feynman's formulation of quantum mechanics. A transition amplitude is represented as a sum over virtual paths which different intermediate measur…
Path integrals, the ABL rule and the three-box paradox
D. Sokolovski*, I. Puerto Gimenez, R. Sala Mayato
The three-box problem is analysed in terms of virtual pathways, interference between which is destroyed by a number of intermediate measurements. The Aharonov-Bergmann-Lebowitz (AB…
Ground-State Entanglement in a Coupled-Cavity Model
E. K. Irish
Bipartite entanglement entropies are calculated for the ground state of the two-excitation subspace in a two-site coupled cavity model. Each region in the phase diagram (atomic ins…
Characterizing multipartite symmetric Dicke states under the effects of noise
S. Campbell, M. S. Tame, M. Paternostro
We study genuine multipartite entanglement (GME) in a system of qubits prepared in symmetric Dicke states and subjected to the influences of noise. We provide general, setup-in…
Experimental realization of Dicke states of up to six qubits for multiparty quantum networking
R. Prevedel, G. Cronenberg, M. S. Tame +4
We report the first experimental generation and characterization of a six-photon Dicke state. The produced state shows a fidelity of F=0.56+/-0.02 with respect to an ideal Dicke st…
Scheme for proving the bosonic commutation relation using single-photon interference
M. S. Kim, H. Jeong, A. Zavatta +2
We propose an experiment to directly prove the commutation relation between bosonic annihilation and creation operators, based on the recent experimental success in single-photon s…
Long-range surface plasmon polariton excitation at the quantum level
D. Ballester, M. S. Tame, C. Lee +2
We provide the quantum mechanical description of the excitation of long-range surface plasmon polaritons (LRSPPs) on thin metallic strips. The excitation process consists of an att…
