Eavesdropping on the "ping-pong" type quantum communication protocols with invisible photon
Qing-yu Cai
The crucial issue of quantum communication protocol is its security. In this paper, we show that all the deterministic and direct two-way quantum communication protocols, sometimes…
Photon-number-solving Decoy State Quantum Key Distribution
Qing-yu Cai, Yong-gang Tan
In this paper, a photon-number-resolving decoy state quantum key distribution scheme is presented based on recent experimental advancements. A new upper bound on the fraction of co…
Improving the security of multiparty quantum secret sharing against Trojan horse attack
Fu-Guo Deng, Xi-Han Li, Hong-Yu Zhou +1
We analyzed the security of the multiparty quantum secret sharing (MQSS) protocol recently proposed by Zhang, Li and Man [Phys. Rev. A \textbf{71}, 044301 (2005)] and found that th…
Ultracold two-component Fermi gases with a magnetic field gradient near a Feshbach resonance
Hongwei Xiong, Shujuan Liu, Weiping Zhang +1
We study theoretically the ultracold two-component Fermi gases when a gradient magnetic field is used to tune the scattering length between atoms. For Li6 at the narrow resonance B…
Interference of Bose-Einstein condensates and entangled single-atom state in a spin-dependent optical lattice
Linghua Wen, Min Liu, Hongwei Xiong +1
We present a theoretical model to investigate the interference of an array of Bose-Einstein condensates loaded in a one-dimensional spin-dependent optical lattice, which is based o…
Bose-Einstein Condensation of Particle-Hole Pairs in Ultracold Fermionic Atoms Trapped within Optical Lattices
Chaohong Lee
We investigate the Bose-Einstein condensation (BEC, superfluidity) of particle-hole pairs in ultracold Fermionic atoms with repulsive interactionsand arbitrary polarization, which…
