- Title
Reversible projective measurement in quantum ensembles.

- Abstract
We present experimental NMR demonstration of a scheme of reversible projective measurement, which allows extracting information on outcomes and probabilities of a projective measurement in a non-destructive way, with a minimal net effect on the quantum state of an ensemble. The scheme uses reversible dynamics and weak measurement of the intermediate state. The experimental system is an ensemble of Cs ( S = 7/2) nuclei in a liquid-crystalline matrix.
