Experimental demonstration of an efficient quantum phase-covariant cloning and its possible applications to simulating eavesdropping in quantum cryptography
Jiangfeng Du, Thomas Durt, Ping Zou +4
We describe a nuclear magnetic resonance (NMR) experiment which implements an efficient one-to-two qubit phase-covariant cloning machine(QPCCM). In the experiment we have achieved…
About economic qubit cloning
Thomas Durt, Jiangfeng Du
In this paper we establish a deep connection between the 3 qubit one-to-two phase-covariant quantum cloning network of Fuchs et al. [C. Fuchs, N. Gisin, R.B. Griffiths, C.S. Niu, a…
Spatial Localization and Relativistic Transformation of Quantum Spins
Hui Li, Jiangfeng Du
The purity of a reduced state for spins that is pure in the rest frame will most likely appear to degrade because spin and momentum become mixed when viewed by a moving observer. W…
Quantum games of asymmetric information
Jiangfeng Du, Hui Li, Chenyong Ju
We investigate quantum games in which the information is asymmetrically distributed among the players, and find the possibility of the quantum game outperforming its classical coun…
An experimental observation of geometric phases for mixed states using NMR interferometry
Jiangfeng Du, Ping Zou, Mingjun Shi +6
Examples of geometric phases abound in many areas of physics. They offer both fundamental insights into many physical phenomena and lead to interesting practical implementations. O…
Playing Prisoner's Dilemma with Quantum Rules
Jiangfeng Du, Xiaodong Xu, Hui Li +2
Quantum game theory is a recently developing field of physical research. In this paper, we investigate quantum games in a systematic way. With the famous instance of the Prisoner's…
