The desired measurement basis is selected by the quantum state of a program register. First we analyze the phase-covariant multimeters for a large class of program states and then the universal multimeters for a special choice of program. In both cases we start with deterministic but error-prone devices and then proceed to devices that never make a mistake but from time to time give an inconclusive result. These multimeters are optimized (for a given type of program) with respect to the minimum probability of an inconclusive result. This concept is further generalized to multimeters that minimize the error rate for a given probability of an inconclusive result (or vice versa). Finally, we propose a generalization for qudits."@en . . "quantum multimeters"@en . . "4"^^ . "[D0FA35D12CA2]" . . . "69" . "Pravd\u011Bpodobnostn\u00ED kvantov\u00E9 multimetry"@cs . "2"^^ . "2"^^ .
