Here is some new work we have done predicting the effects of continuous measurement on cavity-cooled nanospheres: Quantum cooling and squeezing of a levitating nanosphere via time-continuous measurements. We predict that by measuring the cavity output and/or the light scattered from a cavity-cooled nanosphere, and using these measurements to feedback onto the dynamics of the particle, cooling, squeezing and the purity of the quantum state can be improved.

 

Continuously measuring the position and cavity-output can inmprove cooling
