Deterministic Mechanical Wigner Negativity via Nonlinear Cavity Quantum Optomechanics in the Unresolved-Sideband Regime
Jack Clarke, Pascal Neveu, Ewold Verhagen +1
Non-Gaussian quantum states of mechanical motion exhibiting Wigner negativity offer promising capabilities for quantum technologies and tests of fundamental physics. Within the fie…
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…
Enhanced Laser Cooling of a Mechanical Resonator via Zero-Photon Detection
Evan A. Cryer-Jenkins, Kyle D. Major, Jack Clarke +11
Throughout quantum science and technology, measurement is used as a powerful resource for nonlinear operations and quantum state engineering. In particular, single-photon detection…
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…
