Quantum state transmission via a spin ladder as a robust data bus
Y. Li, T. Shi, B. Chen +2
We explore the physical mechanism to coherently transfer the quantum information of spin by connecting two spins to an isotropic antiferromagnetic spin ladder system as data bus. D…
Generalized Quantum Games with Nash Equilibrium
X. F. Liu, C. P. Sun
We define generalized quantum games by introducing the coherent payoff operators and propose a simple scheme to illustrate it. The scheme is implemented with a single spin qubit sy…
Two photon interference and optical free induction decay
P. Zhang, C. P. Sun
The two photon interference phenomenon is theoretically investigated for the general situations with an arbitrary input two photon state with and without photon polarization. For t…
Elementary Excitations in Trapped BEC and Zero Mode Problem
D. L. Zhou, X. X. Yi, G. R. Jin +3
We propose a natural expansion of the atomic field operator in studying elementary excitations in trapped Bose-Einstein Condensation (BEC) system near T=0K. Based on this expansion…
Stability properties of trapped Bose-Fermi gases mixture
X. X. Yi, C. P. Sun
The stability of Bose-Fermi gases trapped in an isotropic potentials at ultracold temperature is strongly influenced by the interaction between the fermions and the bosons. At zero…
Controlling Decoherence in Bose-Einstein Condensation by Light Scattering far off Resonance
C. P. Sun
It is shown that, through a super-radiant Rayleigh scattering, a strong far off-resonant pump laser applied to a Bose-Einstein condensates(BEC) can induce a non-demolition coupling…
