Construction of Elementary Gates in Quantum Computation by Joint Measurement

Jia-Qi Jin, Gui-Lu Long

In this paper, elementary quantum gate operations, such as the phase gate, the controlled-NOT gate, the swap and the Fredkin gate are constructed using joint measurement and pairs…

Distinctness of ensembles having the same density matrix and the nature of liquid NMR quantum computing

Gui-Lu Long, Yi-Fan Zhou, Jia-Qi Jin +1

We show that differently constructed ensembles having the same density matrix may be physically distinguished by observing fluctuations of some observables. An explicit expression…
