Quantum electromechanics with levitated nanoparticles
Lukas Martinetz, Klaus Hornberger, James Millen +2
Preparing and observing quantum states of nanoscale particles is a challenging task with great relevance for quantum technologies and tests of fundamental physics. In contrast to a…
Optical nonclassicality test based on third-order intensity correlations
L. Rigovacca, W. S. Kolthammer, C. Di Franco +1
We develop a nonclassicality criterion for the interference of three delayed, but otherwise identical, light fields in a three-mode Bell interferometer. We do so by comparing the p…
Observation of quantum interference in the plasmonic Hong-Ou-Mandel effect
G. Di Martino, Y. Sonnefraud, M. S. Tame +5
We report direct evidence of the bosonic nature of surface plasmon polaritons (SPPs) in a scattering-based beamsplitter. A parametric down-conversion source is used to produce two…
Quantum Statistics of Surface Plasmon Polaritons in Metallic Stripe Waveguides
Giuliana Di Martino, Yannick Sonnefraud, Stéphane Kéna-Cohen +4
Single surface plasmon polaritons are excited using photons generated via spontaneous parametric down-conversion. The mean excitation rates, intensity correlations and Fock state p…
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…
Hamiltonian tomography in an access-limited setting without state initialization
C. Di Franco, M. Paternostro, M. S. Kim
We propose a scheme for the determination of the coupling parameters in a chain of interacting spins. This requires only time-resolved measurements over a single particle, simple d…
Compact Toffoli gate using weighted graph states
M. S. Tame, S. K. Ozdemir, M. Koashi +2
We introduce three compact graph states that can be used to perform a measurement-based Toffoli gate. Given a weighted graph of six, seven or eight qubits, we show that success pro…
Dynamics in a coupled-cavity array
C. D. Ogden, E. K. Irish, M. S. Kim
The dynamics of a system composed of two coupled optical cavities, each containing a single two-level atom, is studied over a wide range of detuning and coupling values. A descript…
Extraction of Singlet States from Noninteracting High-Dimensional Spins
Francesco Ciccarello, Mauro Paternostro, Myungshik S. Kim +1
We present a scheme for the extraction of singlet states of two remote particles of arbitrary quantum spin number. The goal is achieved through post-selection of the state of inter…
Experimental Realization of Deutsch's Algorithm in a One-way Quantum Computer
M. S. Tame, R. Prevedel, M. Paternostro +3
We report the first experimental demonstration of an all-optical one-way implementation of Deutsch's quantum algorithm on a four-qubit cluster state. All the possible configuration…
Decoherence-based exploration of d-dimensional one-way quantum computation
M. S. Tame, M. Paternostro, C. Hadley +2
We study the effects of amplitude and phase damping decoherence in d-dimensional one-way quantum computation (QC). Our investigation shows how information transfer and entangling g…
Joint measurements and Bell inequalities
Wonmin Son, Erika Andersson, Stephem M. Barnett +1
Joint quantum measurements of non-commuting observables are possible, if one accepts an increase in the measured variances. A necessary condition for a joint measurement to be poss…
Quantum state transfer in imperfect artificial spin networks
M. Paternostro, G. M. Palma, M. S. Kim +1
High-fidelity quantum computation and quantum state transfer are possible in short spin chains. We exploit a system based on a dispersive qubit-boson interaction to mimic XY coupli…
Perspectives for quantum state engineering via high non-linearity in a double-EIT regime
M. Paternostro, M. S. Kim, B. S. Ham
We analyse the possibilities for quantum state engineering offered by a model for Kerr-type non-linearity enhanced by electromagnetically induced transparency (EIT), which was rece…
Quantum nonlocality test for continuous-variable states with dichotomic observables
H. Jeong, W. Son, M. S. Kim +2
There have been theoretical and experimental studies on quantum nonlocality for continuous variables, based on dichotomic observables. In particular, we are interested in two cases…
