Quantum effects observed in optomechanical system
The first direct observations of distinctly quantum optical effects — amplification and squeezing — have been recorded in an optomechanical system.
The step forward points the way to low-power quantum optical devices and enhanced detection of gravitational waves, among other applications.
Fig 1: Berkeley Lab researchers directly observed quantum optical effects — amplification and ponderomotive squeezing — in an optomechanical system. Here the yellow/red regions show amplification; the blue regions show squeezing. On the left is the data, and on the right is the theoretical prediction in the absence of noise.
