Implementation for Solving Random Satisfiability Problems through CNOT-based circuits in a NMR Quantum Processor
Xinhua Peng, Xiwen Zhu, Kelin Gao
We give a general method of construting quantum circuit for random \QTR{it}{satisfiability} (SAT) problems with the basic logic gates such as multi-qubit controlled-NOT and NOT gat…
Nuclear Magnetic Resonance Implemenations of Remote State Preparation of Arbitary Longitudinal Qubit and Remote State Measurement of a Qubit
Xinhua Peng, Xiwen Zhu, Maili Liu +1
A qubit chosen from equatorial or polar great circles on a Bloch sphere can be remotely prepared with an Einstain-Podolsky-Rosen (EPR) state shared and a cbit communication. We gen…
Experimental demonstration of the interferometric complementarity of one- and two-particle interference in a bulk Nuclear Magnetic Resonance ensemble
Xinhua Peng, Xiwen Zhu, Maili Liu +1
We analyze an interferometric complementarity between one- and two-particle interference in the general case: , , and further examine the rel…
Exhibition of the periodicity of Quantum Fourier Transformation in Nuclear Magnetic Resonance
Xinhua Peng, Xiwen Zhu, Ximing Fang +4
The remarkable capability of quantum Fourier transformation (QFT) to extract the periodicity of a given periodic function has been exhibited by using nuclear magnetic resonance (NM…
Avalanche dynamics in Bak-Sneppen evolution model observed with standard distribution width of fitness
Chaohong Lee, Xiwen Zhu, Kelin Gao
We introduce the standard distribution width of fitness to characterize the global and individual features of a ecosystem in the Bak-Sneppen evolution model. Through tracking this…
Classical calculation of high-order harmonic generation of atomic and molecular gases in intense laser fields
Chaohong Lee, Yiwu Duan, Wing-Ki Liu +4
Based upon our previous works (Eur.Phys.J.D 6, 319(1999); Chin.Phys.Lett. 18, 236(2001)), we develop a classical approach to calculate the high-order harmonic generation of the las…
