Dephasing of multiparticle Rydberg excitations for fast entanglement generation
multiparticle Rydberg excitations fast entanglement generation Quantum Physics
2011/8/17
Abstract: An approach to fast entanglement generation based on Rydberg dephasing of collective excitations (spin-waves) in large, optically thick atomic ensembles is proposed. Long-range $1/r^3$ atomi...

Driving LED in a Nanosecond Regime by a Fast Operational Amplifier
Driving LED Operational Amplifier
2010/11/17
It is widely believed that the generation of high speed optical signals is not the job for an LED. However this work is done to show that there are techniques which can be used to produce nanosecond ...
