Entanglement-Enhanced Matter-Wave Interferometry in a High-Finesse Cavity
Graham P. Greve, Chengyi Luo, Baochen Wu +1
Entanglement is a fundamental resource that allows quantum sensors to surpass the standard quantum limit set by the quantum collapse of independent atoms. Collective cavity-QED sys…
Site-dependent selection of atoms for homogeneous atom-cavity coupling
Baochen Wu, Graham P. Greve, Chengyi Luo +1
We demonstrate a method to obtain homogeneous atom-cavity coupling by selecting and keeping Rb atoms that are near maximally coupled to the cavity's standing-wave mode. We s…
Continuous real-time tracking of a quantum phase below the standard quantum limit
Athreya Shankar, Graham P. Greve, Baochen Wu +2
We propose a scheme for continuously measuring the evolving quantum phase of a collective spin composed of pseudospins. Quantum non-demolition measurements of a lossy cavity mo…
Laser Cooling with Adiabatic Transfer on a Raman Transition
Graham P. Greve, Baochen Wu, James K. Thompson
A novel laser cooling mechanism was recently demonstrated using a narrow-linewidth optical transition. Counter-propagating laser beams are swept in frequency to cause adiabatic tra…
Spatially Homogeneous Entanglement for Matter-Wave Interferometry Created with Time-Averaged Measurements
Kevin C. Cox, Graham P. Greve, Baochen Wu +1
We demonstrate a method to generate spatially homogeneous entangled, spin-squeezed states of atoms appropriate for maintaining a large amount of squeezing even after release into t…
Deterministic Squeezed States with Joint Measurements and Feedback
Kevin C. Cox, Graham P. Greve, Joshua M. Weiner +1
We demonstrate the creation of entangled, spin-squeezed states using a collective, or joint, measurement and real-time feedback. The pseudospin state of an ensemble of $N= 5\times…
Generating Entanglement between Atomic Spins with Low-Noise Probing of an Optical Cavity
Kevin C. Cox, Joshua M. Weiner, Graham P. Greve +1
Atomic projection noise limits the ultimate precision of all atomic sensors, including clocks, inertial sensors, magnetometers, etc. The independent quantum collapse of atoms i…
