Bell Test of Photons from Electron-Positron Annihilation via POVM-based Compton Polarimetry
Jack Clarke, Preslav Asenov, Jesse Smeets +3
Quantum entanglement between gamma-ray photons emitted following electron-positron annihilation is expected to be maximal and may be characterized via non-classical polarization co…
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…
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…
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…
Cavity quantum optomechanical nonlinearities and position measurement beyond the breakdown of the linearized approximation
Jack Clarke, Pascal Neveu, Kiran E. Khosla +2
Several optomechanics experiments are now entering the highly sought nonlinear regime where optomechanical interactions are large even for low light levels. Within this regime, new…
Can the displacemon device test objective collapse models?
Lydia A. Kanari-Naish, Jack Clarke, Michael R. Vanner +1
Testing the limits of the applicability of quantum mechanics will deepen our understanding of the universe and may shed light on the interplay between quantum mechanics and gravity…
Non-Gaussian mechanical motion via single and multi-phonon subtraction from a thermal state
Georg Enzian, Lars Freisem, John J. Price +7
Quantum optical measurement techniques offer a rich avenue for quantum control of mechanical oscillators via cavity optomechanics. In particular, a powerful yet little explored com…
Preparation and Verification of Two-Mode Mechanical Entanglement Through Pulsed Optomechanical Measurements
Pascal Neveu, Jack Clarke, Michael R. Vanner +1
We propose a protocol how to generate and verify bipartite Gaussian entanglement between two mechanical modes coupled to a single optical cavity, by means of short optical pulses a…
