Relativistic Self-Focusing of Hermite-cosine-Gaussian Laser Beam in Collisionless Plasma with Exponential Density Transition
《Communications in Theoretical Physics》2019年第6期736-740,共5页Vishal Thakur Manzoor Ahmad Wani Niti Kant 
This work reveals an exploration of self-focusing of Hermite-cosine-Gaussian laser beam in a collisionless plasma under relativistic nonlinearity. Self-focusing along with self-trapping of Hermite-cosine-Gaussian lase...

Optimal Phase-Covariant Cloning in 3 Dimensions
《Communications in Theoretical Physics》2012年第6期991-994,共4页张文海 余龙宝 曹卓良 叶柳 
Supported by the National Natural Science Foundation of China under Grant Nos. 11074002,61073048,and 11104057;the Natural Science Foundation of the Education Department of Anhui Province of China under Grant Nos. KJ2010ZD08,KJ2012A245;the Postgraduate Program of Huainan Normal University
In this paper,we present the explicit transformations of the optimal 1 → 3,4,5 phase-covariant cloning in 3 dimensions.The cloning fidelities are covered by the theoretical bounds of the optimal 1 → 3k,3k + 1,3k + 2...

Implementing 1 → M Economical Phase-Covariant Telecloning in Cavity QED
《Communications in Theoretical Physics》2011年第3期441-444,共4页XUE Li JIANG Nian-Quan 
Supported by the Special Funds of the National Natural Science Foundation of China under Grant No. 10947017/A05
We propose an experimentally feasible scheme to implement the economical 1 → M phase-covariant telecloning based on cavity QED. By the resonant interaction of the atoms with cavity field of a high-Q cavity and the di...

Scheme for Implementation of Ancillary-Free 1→3 Optimal Phase-Covariant Quantum Cloning with Trapped Ions
《Communications in Theoretical Physics》2008年第6期1499-1501,共3页YANG Rong-Can LI Hong-Cai LIN Xiu HUANG Zhi-Ping XIE Hong 
National Natural Science Foundation under Grant Nos.1.0574022 and 10575022;the Natural Science Foundation of Fujian Province under Grant Nos.Z0512006 and A0210014
We propose a simple scheme for the implementation of the ancillary-free 1→3 optimal phase-covariant quantum cloning for x-y equatorial qubits in ion-trap system. In the scheme, the vibrational mode is only virtually ...
