Exploiting nonclassical motion of a trapped ion crystal for quantum-enhanced metrology of global and differential spin rotations
R. J. Lewis-Swan, J. C. Zuñiga Castro, D. Barberena +1
We theoretically investigate prospects for the creation of nonclassical spin states in trapped ion arrays by coupling to a squeezed state of the collective motion of the ions. The…
Trade-offs between unitary and measurement induced spin squeezing in cavity QED
Diego Barberena, Anjun Chu, James K. Thompson +1
We study the combined effects of measurements and unitary evolution on the preparation of spin squeezing in an ensemble of atoms interacting with a single electromagnetic field mod…
Driven-dissipative four-mode squeezing of multilevel atoms in an optical cavity
Bhuvanesh Sundar, Diego Barbarena, Ana Maria Rey +1
We utilize multilevel atoms trapped in a driven resonant optical cavity to produce scalable multi-mode squeezed states for quantum sensing and metrology. While superradiance or col…
Critical steady states of all-to-all squeezed and driven superradiance: An analytic approach
Diego Barberena, Ana Maria Rey
We analyse the properties across steady state phase transitions of two all-to-all driven-dissipative spin models that describe possible dynamics of N two-level systems inside an op…
Observing dynamical phases of BCS superconductors in a cavity QED simulator
Dylan J. Young, Anjun Chu, Eric Yilun Song +7
In conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, electrons with opposite momenta bind into Cooper pairs due to an attractive interaction mediated by phonons in the…
Ultra Narrow Linewidth Frequency Reference via Measurement and Feedback
Diego Barberena, Robert J. Lewis-Swan, Ana Maria Rey +1
The generation of very narrow linewidth light sources is of great importance in modern science. One such source is the superradiant laser, which relies on collectively interacting…
Squeezing multilevel atoms in dark states via cavity superradiance
Bhuvanesh Sundar, Diego Barberena, Ana Maria Rey +1
We describe a method to create and store scalable and long-lived entangled spin-squeezed states within a manifold of many-body cavity dark states using collective emission of light…
