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…
Phase Synchronization between Two Superradiant Lasers
Joshua M. Weiner, Kevin C. Cox, Justin G. Bohnet +1
We experimentally demonstrate synchronization between two distinct ensembles of cold atoms undergoing steady state superradiance within a single longitudinal and transverse mode of…
Reducing Collective Quantum State Rotation Errors with Reversible Dephasing
Kevin C. Cox, Matthew A. Norcia, Joshua M. Weiner +2
We demonstrate that reversible dephasing via inhomogeneous broadening can greatly reduce collective quantum state rotation errors, and observe the suppression of rotation errors by…
Phase diagram for injection locking a superradiant laser
Kevin C. Cox, Joshua M. Weiner, James K. Thompson
We experimentally and theoretically study the response of a superradiant or bad-cavity laser to an applied coherent drive. We observe two forms of synchronization (injection lockin…
Linear response theory for superradiant lasers
Justin G. Bohnet, Zilong Chen, Joshua M. Weiner +2
We theoretically study a superradiant laser, deriving both the steady-state behaviors and small-amplitude responses of the laser's atomic inversion, atomic polarization, and light…
