Cavity-aided non-demolition measurements for atom counting and spin squeezing
Zilong Chen, Justin G. Bohnet, Joshua M. Weiner +2
Probing the collective spin state of an ensemble of atoms may provide a means to reduce heating via the photon recoil associated with the measurement and provide a robust, scalable…
Superradiant Raman Laser Magnetometer
Joshua M. Weiner, Kevin C. Cox, Justin G. Bohnet +2
We demonstrate a proof-of-principle magnetometer that relies on the active oscillation of a cold atom Raman laser to continuously map a field-sensitive atomic phase onto the phase…
Relaxation oscillations, stability, and cavity feedback in a superradiant Raman laser
Justin G. Bohnet, Zilong Chen, Joshua M. Weiner +2
We experimentally study the relaxation oscillations and amplitude stability properties of an optical laser operating deep into the bad-cavity regime using a laser-cooled Rb…
Dynamically controlled superradiant laser for hybrid sensing of collective atomic coherence
Justin G. Bohnet, Zilong Chen, Joshua M. Weiner +2
We implement dynamic control of a superradiant, cold atom Rb Raman laser to realize the equivalent of conditional Ramsey spectroscopy for sensing atomic phase shifts. Our me…
General Formalism for Evaluating the Impact of Phase Noise on Bloch Vector Rotations
Zilong Chen, Justin G. Bohnet, Joshua M. Weiner +1
Quantum manipulation protocols for quantum sensors and quantum computation often require many single qubit rotations. However, the impact of phase noise in the field that performs…
A low phase noise microwave source for atomic spin squeezing experiments in 87Rb
Zilong Chen, Justin G. Bohnet, Joshua M. Weiner +1
We describe and characterize a simple, low cost, low phase noise microwave source that operates near 6.800 GHz for agile, coherent manipulation of ensembles of 87Rb. Low phase nois…
