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…
Quantum Correlations in Two-Boson Wavefunctions
R. Paskauskas, L. You
We present the Schmidt decomposition for arbitrary wavefunctions of two indistinguishable bosons, extending the recent studies of entanglement or quantum correlations for two fermi…
Propagation of Raman-matched laser pulses through a Bose-Einstein condensate
Özgür E. Müstecaplıoğlu, L. You
We investigate the role of non-uniform spatial density profiles of trapped atomic Bose-Einstein condensates in the propagation of Raman-matched laser pulses under conditions for el…
