Correlated two-photon emission by transitions of Dirac-Volkov states in intense laser fields: QED predictions

E. Lötstedt, U. D. Jentschura

In an intense laser field, an electron may decay by emitting a pair of photons. The two photons emitted during the process, which can be interpreted as a laser-dressed double Compt…

Quantum entanglement in dense multiqubit systems

M. Macovei, J. Evers, C. H. Keitel

The pairwise entanglement of an arbitrary atomic pair randomly extracted from a laser-driven dense multiqubit sample in the presence of quantum dissipation due to spontaneous emiss…

Multipartite W states for chains of atoms conveyed through an optical cavity

D. Gonta, S. Fritzsche

We propose and work out a scheme to generate the entangled W states for a chain of N four-level atoms which are transported through an optical cavity by means of an optical lattice…

Measurement of distance and orientation of two atoms in arbitrary geometry

Qurrat-ul-Ain Gulfam, Joerg Evers

Accurate measurement of relative distance and orientation of two nearby quantum particles is discussed. We are in particular interested in a realistic description requiring as litt…

Nonperturbative treatment of double Compton backscattering in intense laser fields

E. Lötstedt, U. D. Jentschura

The emission of a pair of entangled photons by an electron in an intense laser field can be described by two-photon transitions of laser-dressed, relativistic Dirac--Volkov states.…

Universal quantum Controlled-NOT gate

Michael Siomau, Stephan Fritzsche

An investigation of an optimal universal unitary Controlled-NOT gate that performs a specific operation on two unknown states of qubits taken from a great circle of the Bloch spher…

Generation of two-dimensional cluster states by using high-finesse bimodal cavities

D. Gonta, S. Fritzsche, T. Radtke

We propose two novel schemes to generate the two-dimensional 2xN and 3xN cluster states by using a chain of (two-level) Rydberg atoms in the framework of cavity QED. These schemes…

Spontaneous emission interference in negative-refractive-index waveguides

G. X. Li, J. Evers, C. H. Keitel

The spontaneous decay of a V-type three-level atom placed in a negative-refractive-index waveguide is analyzed. We find that in thin waveguides, highly efficient surface guided mod…

Ground state cooling of a nanomechanical resonator in the weak-confinement regime via quantum interference

K. Xia, J. Evers

Ground state cooling of a nanomechanical resonator coupled to a superconducting flux qubit is discussed. We show that by inducing quantum interference to cancel detrimental carrier…

Phase modulation induced by cooperative effects in electromagnetically induced transparency

R. Fleischhaker, T. N. Dey, J. Evers

We analyze the influence of dipole-dipole interactions in an electromagnetically induced transparency setup at high density. We show both analytically and numerically that the pola…

Sub-wavelength position measurements with running wave driving fields

J. Evers, S. Qamar

A scheme for sub-wavelength position measurements of quantum particles is discussed, which operates with running-wave laser fields as opposed to standing wave fields proposed in pr…
