Adiabatic Condition and Quantum Geometric Potential (2008)
Wu, Jianda, Zhao, Meisheng, Chen, Jianlan, Zhang, Yongde
In this paper, we present a U(1)-invariant expansion theory of the adiabatic process. As its application, we propose and discuss new sufficient adiabatic approximation conditions. In the new...
Intelligent Transportation Systems An Automated Gas Station Attendant (2008)
Alberto Broggi, Shiu Kit Tso, Ka Lun Fan, Yongde Zhang, Chun Man Chan, Hong Kong
So far, this department has covered many different aspects of intelligent transportation systems: innovative vehicles and transportation methods, new ideas for infrastructures and public transport,...
The fidelity of general bosonic channels with pure state input (2006)
Zhao, Meisheng, Qin, Tao, Zhang, Yongde
We first derive for the general form of the fidelity for various bosonic channels. Thereby we give the fidelity of different quantum bosonic channel, possibly with product input and entangled input...
The classical capacity for continuous variable teleportation channel (2006)
Qin, Tao, Zhao, Meisheng, Zhang, Yongde
The process of quantum teleportation can be considered as a quantum channel. The exact classical capacity of the continuous variable teleportation channel is given. Also, the channel fidelity is...
Membrane potassium currents in human radial artery and their regulation by nitric oxide donor (2006)
Zhang, Yongde, Tazzeo, Tracy, Chu, Victor, Janssen, Luke J.
Objective The human radial artery has demonstrated superior long-term results as a graft in coronary bypass surgery, but undesirable post-surgical spasm limits its clinical application. Few have...
The classical capacity for the quantum Markov channel of continuous variables (2005)
Qin, Tao, Zhao, Meisheng, Zhang, Yongde
Quantum communications using continuous variables are quite mature experimental techniques and the relevant theories have been extensively investigated with various methods. In this paper, we study...
A necessary and sufficient criterion for multipartite separable states (2000)
Wu, Shengjun, Chen, Xuemei, Zhang, Yongde
We present a necessary and sufficient condition for the separability of multipartite quantum states, this criterion also tells us how to write a multipartite separable state as a convex sum of...
Controlled Quantum Teleportaion (2000)
Zhou, Jindong, Hou, Guang, Wu, Shenjun, Zhang, Yongde
A theoretical scheme for controlled quantum teleportation is presented, using the entanglement property of GHZ state.
Calculating the relative entropy of entanglement (2000)
We extend Vedral and Plenio's theorem (theorem 3 in Phys. Rev. A 57, 1619) to a more general case, and obtain the relative entropy of entanglement for a class of mixed states, this result can also...
Multipartite pure-state entanglement and the generalized GHZ states (2000)
We show that not all 4-party pure states are GHZ reducible (i.e., can be generated reversibly from a combination of 2-, 3- and 4-party maximally entangled states by local quantum operations and...
Classical Capacity of A Quantum Multiple Access Channel (1999)
Huang, Minxin, Zhang, Yongde, Hou, Guang
We consider the transmission of classical information over a quantum channel by two senders. The channel capacity region is shown to be a convex hull bound by the Von Neumann entropy and the...
Vascular relaxation response to hydrogen peroxide is impaired in hypertension
Gao, Yu-Jing, Zhang, Yongde, Hirota, Simon, Janssen, Luke J
In phenylephrine (1 μM)-precontracted rat superior mesenteric arteries (MA), hydrogen peroxide (H2O2, 0.3 and 1 mM) caused a biphasic response: a transient contraction followed by a relaxation. In...
