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…
