>VITAE: Jaromir Fiurasek is a postdoctoral research fellow at the Ecole Polytechnique, Universite Libre de Bruxelles, Belgium. His research interests include quantum information theory and quantum optics. He received his Ph.D. in Physics from the Palacky University Olomouc, Czech Republic.
|Programmable quantum multimeters are devices that can approximately
realize various projective measurements on a qubit. The desired measurement
basis is selected by the quantum state of a program register. We first describe
deterministic but error-prone multimeters and then proceed to devices that
never make a mistake but from time to time they give an inconclusive result.
These multimeters are optimized (for a given type of a program) with respect to the minimum probability of inconclusive result.
Experimental optical implementation of simplest quantum multimeters will be reported.
