A conditional quantum phase gate between two 3-state atoms
X. X. Yi, X. H. Su, L. You
We propose a scheme for conditional quantum logic between two 3-state atoms that share a quantum data-bus such as a single mode optical field in cavity QED systems, or a collective…
Quantum logic between atoms inside a high Q optical cavity
L. You, X. X. Yi, X. H. Su
We propose a protocol for conditional quantum logic between two 4-state atoms inside a high Q optical cavity. The process detailed in this paper utilizes a direct 4-photon 2-atom r…
Decoherence of collective atomic spin states due to inhomogeneous coupling
C. P. Sun, S. Yi, L. You
We investigate the decoherence of a superposition of symmetric collective internal states of an atomic ensemble due to inhomogeneous coupling to external control fields. For asympt…
Spin squeezing and entanglement in spinor-1 condensates
Özgür E. Müstecaplıoğlu, M. Zhang, L. You
We analyze quantum correlation properties of a spinor-1 (f=1) Bose Einstein condensate using the Gell-Mann realization of SU(3) symmetry. We show that previously discussed phenomen…
