Spin squeezing of atomic ensembles via nuclear-electronic spin entanglement.
We demonstrate spin squeezing in a room temperature ensemble of approximately 10(12) cesium atoms using their internal structure, where the necessary entanglement is created between nuclear and electronic spins of each individual atom. This state provides improvement in measurement sensitivity beyond the standard quantum limit for quantum memory experiments and applications in quantum metrology...
متن کاملThree-dimensional light-matter interface for collective spin squeezing in atomic ensembles
We study the three-dimensional nature of the quantum interface between an ensemble of cold, trapped atomic spins and a paraxial laser beam, coupled through a dispersive interaction. To achieve strong entanglement between the collective atomic spin and the photons, one must match the spatial mode of the collective radiation of the ensemble with the mode of the laser beam while minimizing the eff...

متن کاملSpin Squeezing on an Atomic-Clock Transition
We generate input states with reduced quantum uncertainty (spin-squeezed states) for a hyperfine atomic clock by collectively coupling an ensemble of laser-cooled and trapped 87Rb atoms to an optical resonator. A quantum nondemolition measurement of the population difference between the two clock states with far-detuned light produces an entangled state whose projection noise is reduced by as m...
متن کاملEntanglement and spin squeezing in the two - atom Dicke model
We analyze the relation between the entanglement and spin-squeezing parameter in the two-atom Dicke model and identify the source of the discrepancy recently reported by Banerjee and Zhou et al that one can observe entanglement without spin squeezing. Our calculations demonstrate that there are two criteria for entanglement, one associated with the two-photon coherences that create two-photon e...
