Narrow Spectral Feature In Resonance Fluorescence With A Single Monochromatic Laser Field

Joerg Evers, Christoph H. Keitel

We describe the resonance fluorescence spectrum of an atomic three-level system where two of the states are coupled by a single monochromatic laser field. The influence of the thir…

An arbitrated quantum signature scheme

Guihua Zeng, Christoph H. Keitel

The general principle for a quantum signature scheme is proposed and investigated based on ideas from classical signature schemes and quantum cryptography. The suggested algorithm…

A Non-Adiabatic Controlled Not Gate for the Kane Solid State Quantum Computer

C. Wellard, L. C. L. Hollenberg, H. C. Pauli

The method of iterated resolvents is used to obtain an effective Hamiltonian for neighbouring qubits in the Kane solid state quantum computer. In contrast to the adiabatic gate pro…

Modelling the Recoherence of Mesoscopic Superpositions in Dissipative Environments

S. G. Mokarzel, A. N. Salgueiro, M. C. Nemes

A model is presented to describe the recently proposed experiment (J. Raimond, M. Brune and S. Haroche Phys. Rev. Lett {\bf 79}, 1964 (1997)) where a mesoscopic superposition of ra…

Supersymmetric and Shape-Invariant Generalization for Nonresonant and Intensity-Dependent Jaynes-Cummings Systems

A. N. F. Aleixo, A. B. Balantekin, M. A. Candido Ribeiro

A class of shape-invariant bound-state problems which represent transition in a two-level system introduced earlier are generalized to include arbitrary energy splittings between t…
