Splitting of quantum information in traveling wave fields using only linear optical elements
W. B. Cardoso, N. G. de Almeida, A. T. Avelar +1
In this brief report we present a feasible scheme to split quantum information in the realm of traveling waves. An oversimplified scheme is also proposed for the generation of a cl…
Solitons with Cubic and Quintic Nonlinearities Modulated in Space and Time
A. T. Avelar, D. Bazeia, W. B. Cardoso
This work deals with soliton solutions of the nonlinear Schroedinger equation with cubic and quintic nonlinearities. We extend the procedure put forward in a recent Letter and we s…
Generation of arbitrary Fock states via resonant interactions in cavity QED
Gisana C. A. Bueno, W. B. Cardoso, A. T. Avelar +1
We propose a scheme to generate arbitrary Fock states |N> in a cavity QED using N resonant Rydberg atoms. The atom-field interaction times are controlled via Stark-shifts adjusted…
Partial teleportation of entangled atomic states
W. B. Cardoso, N. G. de Almeida
In this paper we propose a scheme for partially teleporting entangled atomic states. Our scheme can be implemented using only four two-level atoms interacting either resonantly or…
Quantum teleportation in superconducting charge qubits
R. M. Gomes, W. B. Cardoso, A. T. Avelar +1
In this paper we propose a scheme to implement a quantum teleportation based on the current experimental design [Nature (London) 431, 162 (2004); ibid 445, 515 (2007)] in which sup…
Generation of four-qubit cluster of entangled coherent states in bimodal QED cavities
E. M. Becerra-Castro, W. B. Cardoso, A. T. Avelar +1
A recent work [1] proposed a type of cluster entangled coherent states and its generation. Here we present an alternative experimental arrangement for its generation in bimodal QED…
