Parametric Amplification of Vacuum Fluctuations in a Spinor Condensate
Parametric Amplification of Vacuum Fluctuations in a Spinor Condensate
Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplification of vacuum fluctuations for matter waves using a spinor F=2 87Rb condensate. Interatomic interactions lead to correlated pair creation in the mF=±1 states from an initial mF=0 …
