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…
