Multipartite Einstein-Podolsky-Rosen steering and genuine tripartite entanglement with optical networks
Seiji Armstrong, Meng Wang, Run Yan Teh +6
The Einstein-Podolsky-Rosen (EPR) paradox established a link between entanglement and nonlocality in quantum mechanics. EPR steering is the nonlocality associated with the EPR para…
Theoretical Analysis of an Ideal Noiseless Linear Amplifier for Einstein-Podolsky-Rosen Entanglement Distillation
J. Bernu, S. Armstrong, T. Symul +2
We study the operational regime of a noiseless linear amplifier based on quantum scissors that can nondeterministically amplify the one photon component of a quantum state with wea…
Quasipinning and selection rules for excitations in atoms and molecules
Carlos L. Benavides-Riveros, Michael Springborg
Postulated by Pauli to explain the electronic structure of atoms and molecules, the exclusion principle establishes an upper bound of 1 for the fermionic natural occupation numbers…
Electromagnetically induced transparency and four-wave mixing in a cold atomic ensemble with large optical depth
J. Geng, G. T. Campbell, J. Bernu +7
We report on the delay of optical pulses using electromagnetically induced transparency in an ensemble of cold atoms with an optical depth exceeding 500. To identify the regimes in…
