Abstract
	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.
