General Description of Mixed State Geometric Phase
Mingjun Shi, Jiangfeng Du
We consider arbitrary mixed state in unitary evolution and provide a comprehensive description of corresponding geometric phase in which two different points of view prevailing cur…
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…
Implementations of Nonadiabatic Geometric Quantum Computation using NMR
Jiangfeng Du, Mingjun Shi, Jihui Wu +2
Recently, geometric phases, which is fault tolerate to certain errors intrinsically due to its geometric property, are getting considerable attention in quantum computing theoretic…
Realization of Fredkin Gate by Three Transition Pulses in NMR Quantum Information Processor
Xue Fei, Du Jiangfeng, Shi Mingjun +3
The three-qubit conditional swap gate(Fredkin gate) is a universal gate that can be used to create any logic circuit and has many direct usages. In this paper, we experimentally re…
Boundary of the Set of Separable States
Mingjun Shi, Jiangfeng Du
The set of all separable quantum states is compact and convex. We focus on the two-qubit quanum system and study the boundary of the set. Then we give the criterion to determine wh…
Remark On Quantum Battle of The Sexes Game
Jiangfeng Du, Hui Li, Xiaodong Xu +3
Recently Quantum Battle of The Sexes Game has been studied by Luca Marinatto and Tullio Weber. Yet some important problems exist in their scheme. Here we propose a new scheme to qu…
