Cluster state generation using van der Waals and dipole-dipole interactions in optical lattices
ipole-dipole interactions optical lattices
2011/9/9
We present a scalable method for generation of a cluster state for measurement-based quantum computing using van der Waals or dipole-dipole interactions between neutral atoms or polar molecules in an ...
An Optical Fibre Pulse Rate Multiplier for Ultra-low Phase-noise Signal Generation
Optical Fibre Ultra-low Phase-noise Signal
2011/9/6
In this letter we report on an all optical-fibre approach to the synthesis of ultra-low noise microwave signals by photodetection of femtosecond laser pulses. We use a cascade of Mach-Zehnder fibre in...

Acousto-optical random phase jumps coherence tomography
2011/9/6
Acousto-Optical Coherence Tomography (AOCT) is variant of Acousto Optic Imaging (called also ultrasonic modulation imaging) that makes possible to get z resolution with acoustic and optic Continuous W...

Characterization of excited states ultracold atoms optical lattices
2011/9/15
Loading ultracold atoms in an optical lattice from a Bose-Einstein condensate is generally a nonadiabatic process resulting in the dynamical excitation of a wavepacket, a combination of several eigens...
Feasible optical weak measurements of complementary observables via a single Hamiltonian
optical weak measurements Hamiltonian optical weak measurements
2011/9/15
We show that the process of three-wave mixing in a non-linear crystal (such as employed in down conversion processes) can be used for versatile weak measurements. That is the crystal field interaction...

2011/7/7
The modulational instability and discrete matter wave solitons in dipolar BEC, loaded into a deep optical lattice, are investigated analytically and numerically. The process of modulational instabilit...
Optical Excitation and Decay Dynamics of Ytterbium Atoms Embedded in a Solid Neon Matrix
Ytterbium Atoms Embedded Optical Excitation and Decay Dynamics
2011/9/2
Neutral ytterbium atoms embedded in solid neon qualitatively retain the structure of free atoms. Despite the atom-solid interaction, the 6s6p 3P0 level is found to remain metastable with its lifetimes...
