Generation of a macroscopic singlet state in an atomic ensemble

Generation of a macroscopic singlet state in an atomic ensemble

We report on an experiment underway for generating singlet states in a cold atomic ensemble. We use quantum non-demolition measurement and feedback control to produce a macroscopic spin state with total spin zero and reduced spin fluctuations. We have developed a new detection system with the capabi...

Zusammenfassung:We report on an experiment underway for generating singlet states in a cold atomic ensemble. We use quantum non-demolition measurement and feedback control to produce a macroscopic spin state with total spin zero and reduced spin fluctuations. We have developed a new detection system with the capability of real time measurement and feedback control. Simulations indicate that optical pumping is a good candidate for feedback.
