Quantification of complementarity in multi-qubit systems
Xinhua Peng, Xiwen Zhu, Dieter Suter +3
Complementarity was originally introduced as a qualitative concept for the discussion of properties of quantum mechanical objects that are classically incompatible. More recently,…
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…
"Spectral Implementation" for creating a labeled pseudo-pure state and the Bernstein-Vazirani's algorithm in a four-qubit nuclear magnetic resonance quantum processor
Xinhua Peng, Xiwen Zhu, Ximing Fang +3
A quantum circuit is introducted to describe the preparation of a labeled pseudo-pure state by mutiplet-component excitation scheme which has been experimentally implemented on a 4…
