Quantum Interference between Two Atoms
For the first time, physicists have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together. This type of experiment, which was carried out with photons around thirty years ago, had so far been impossible to perform with matter, due to the extreme difficulty of creating and manipulating pairs of in...
متن کاملQuantum coherence in two dimensions.
The formation and evaporation of two dimensional black holes are discussed. It is shown that if the radiation in minimal scalars has positive energy, there must be a global event horizon or a naked singularity. The former would imply loss of quantum coherence while the latter would lead to an even worse breakdown of predictability. CPT invariance would suggest that there ought to be past horizo...
متن کاملObservation of Rydberg blockade between two atoms
Blockade interactions whereby a single particle prevents the flow or excitation of other particles provide a mechanism for control of quantum states, including entanglement of two or more particles. Blockade has been observed for electrons1–3, photons4 and cold atoms5. Furthermore, dipolar interactions between highly excited atoms have been proposed as a mechanism for ‘Rydberg blockade’6,7, whi...
متن کاملFast adiabatic quantum state transfer and entanglement generation between two atoms via dressed states
We propose a dressed-state scheme to achieve shortcuts to adiabaticity in atom-cavity quantum electrodynamics for speeding up adiabatic two-atom quantum state transfer and maximum entanglement generation. Compared with stimulated Raman adiabatic passage, the dressed-state scheme greatly shortens the operation time in a non-adiabatic way. By means of some numerical simulations, we determine the ...
متن کاملSuperradiance from an ultrathin film of three-level V -type atoms: Interplay between splitting, quantum coherence and local-field effects
We carry out a theoretical study of the collective spontaneous emission (superradiance) from an ultrathin film comprised of three-level atoms with V configuration of the operating transitions. As the thickness of the system is small compared to the emission wavelength inside the film, the local-field correction to the averaged Maxwell field is relevant. We show that the interplay between the lo...
