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...
Wave function multifractality and dephasing at metal-insulator and quantum Hall transitions
Anderson transitions Quantum Hall effect dephasing multifractality
2010/11/23
We analyze the critical behavior of the dephasing rate induced by short-range electron-electron interaction near an Anderson transition of metal-insulator or quantum Hall type. The corresponding expon...
