Quantum Multiplexing with the Orbital Angular Momentum of light
Quantum Multiplexing Orbital Angular Momentum of light
2010/4/12
The orbital angular momentum, OAM, of photons offers a suitable support to carry the quantum data of multiple users. We present two novel optical setups that send the information of n quantum communic...
Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble
Collapses orbital angular momentum light atomic ensemble
2010/4/8
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coher...
