Theoretical framework for enhancing or enabling cooling of a mechanical resonator via the anti-Stokes or Stokes interaction and zero-photon detection

Jack Clarke, Evan A. Cryer-Jenkins, Arjun Gupta +11

We develop a theoretical framework to describe how zero-photon detection may be utilized to enhance laser cooling via the anti-Stokes interaction and, somewhat surprisingly, enable…

Optimizing confidence in negative-partial-transpose-based entanglement criteria

Lydia A. Kanari-Naish, Jack Clarke, Sofia Qvarfort +1

A key requirement of any separable quantum state is that its density matrix has a positive partial transpose. For continuous bipartite quantum states, violation of this condition m…
