Competing many-body interactions in systems of trapped ions
A. Bermudez, D. Porras, M. A. Martin-Delgado
We propose and theoretically analyse an experimental configuration in which lasers induce 3-spin interactions between trapped ions.By properly choosing the intensities and frequenc…
Preparation of Decoherence Free Cluster States with Optical Superlattices
Liang Jiang, Ana Maria Rey, Oriol Romero-Isart +3
We present a protocol to prepare decoherence free cluster states using ultracold atoms loaded in a two dimensional superlattice. The superlattice geometry leads to an array of 2*2…
Discrete coherent states for n qubits
C. Munoz, A. B. Klimov, L. L. Sanchez-Soto +1
Discrete coherent states for a system of qubits are introduced in terms of eigenstates of the finite Fourier transform. The properties of these states are pictured in phase spa…
Nonclassicality of states and measurements by breaking classical bounds on statistics
Ángel Rivas, Alfredo Luis
We derive exceedingly simple practical procedures revealing the quantum nature of states and measurements by the violation of classical upper bounds on the statistics of arbitrary…
Practical schemes for the measurement of angular-momentum covariance matrices in quantum optics
Ángel Rivas, Alfredo Luis
We develop practical schemes for the measurement of the covariance matrix for intrinsic angular-momentum variables in quantum optics. We particularize this approach to two-beam pol…
Full quantum reconstruction of vortex states
I. Rigas, L. L. Sanchez-Soto, A. B. Klimov +2
We propose a complete tomographic reconstruction of any vortex state carrying orbital angular momentum. The scheme determines the angular probability distribution of the state at d…
