Sudden change of interferometric power for X-shape states
《Chinese Physics B》2025年第2期133-139,共7页Dian Zhu Fu-Lin Zhang Jing-Ling Chen 
Project supported by the National Natural Science Foundations of China (Grant Nos. 11675119,12275136,and 12075001);the Nankai Zhide Foundations。
Quantum interferometric power(IP), a discordlike measure, plays an important role in quantum metrology. We study the dynamics of IP for two-qubit X-shape states under different noisy environments. Our study shows that...

Control of sudden transition between classical and quantum correlations of two strongly driven atoms in dissipative cavities
《Chinese Physics B》2013年第8期274-279,共6页穆青霞 
supported by the National Natural Science Foundation of China(Grant Nos.11205056 and 11247308);the Special Funds for the Co-construction Project of Beijing
We investigate analytically the dynamics of classical and quantum correlations between two strongly driven atoms, each of which is trapped inside a dissipative cavity. It is found that there exists a finite time inter...

Evolution of IPv6 Internet topology with unusual sudden changes被引量：6
《Chinese Physics B》2013年第7期602-609,共8页艾均 赵海 Kathleen M. Carley 苏湛 李辉 
the National Natural Science Foundation of China(Grant No.60973022)
The evolution of Internet topology is not always smooth but sometimes with unusual sudden changes. Consequently, identifying patterns of unusual topology evolution is critical for Internet topology modeling and simula...

Sudden birth and sudden death of thermal fidelity in a two-qubit system
《Chinese Physics B》2012年第5期487-493,共7页秦立国 田立君 姜颖 张宏标 
Project supported by the National Natural Science Foundation of China(Grant No.11075101);the Science & Technology Committee of Shanghai Municipality,China(Grant Nos.08dj1400202 and 09PJ1404700);the Training Fund of NENU's Scientific Innvovation Project,China(Grant No.NENU-STC08018);the Ph.D.Program Foundation of Ministry of Education of China (Grant No.20093108110004)
We study the energy level crossing and the thermal fidelity in a two-qubit system with the presence of a transverse inhomogeneous magnetic field.With the help of contour plots,we clearly identify the ground states of ...

Entanglement dynamics of two distant atoms in two detuning cavities被引量：3
《Chinese Physics B》2010年第11期66-72,共7页计新 吕天全 张寿 
Project supported by the National Natural Science Foundation of China (Grant No. 60667001)
We investigate the entanglement dynamics via the concurrence of two distant atoms interacting off-resonantly with two cavity fields in Fock states, respectively. We find that the evolution of entanglement has sudden d...

The entanglement of two moving atoms interacting with a single-mode field via a three-photon process被引量：6
《Chinese Physics B》2010年第2期67-72,共6页吴超 方卯发 
supported by the National Natural Science Foundation of China (Grant No. 10374025);the Natural Science Foundation of Hunan Province (Grant Nos. 07JJ3013 and 07JJ5003);the Research Foundation of the Education Bureau of Hunan Province(Grant No. 06A038)
In this paper, the entanglement of two moving atoms induced by a single-mode field via a three-photon process is investigated. It is shown that the entanglement is dependent on the category of the field, the average p...

Entanglement dynamics of a Heisenberg chain with Dzyaloshinskii-Moriya interaction
《Chinese Physics B》2009年第8期3210-3214,共5页郑强 张小平 支启军 任中洲 
supported by the National Natural Science Foundation of China (Grant Nos 10535010,10775123 and 10865004);Research Fund of the Education Ministry of China (Grant No 20070284016)
This paper investigates the entanglement dynamics of the system, composed of two qubits A and B with Heisenberg XX spin interactation. There is a third controller qubit C, which only has Dzyaloshinskii-Moriya （DM） s...
