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…
