Programmable quantum multimeters and their optical implementatios
Programmable quantum multimeters are devices that can realize any generalized quantum measurement from set (either exactly or approximately). Their main feature is that the desired positive operator valued measure (POVM) is...

Universal Measurement Apparatus Controlled by Quantum Software
We propose a quantum device that can approximate any projective measurement on a qubit-a quantum "multimeter." The desired measurement basis is selected by the quantum state of a "program register." Two different k...

A few experiments of quantum information processing
Manipulation of quantum information attracted a great interest. Quantum physics limits results of some processes. For example, we can not distinguish two non orthogonal states with certainty. Similarly it is impossible to create two...

Quantum multimeters: A programmable state discriminator
We propose a ``programmable'' quantum device that is able to perform a specific generalized measurement from a certain set of measurements depending on a quantum state of a ``program register''. The state of the program register set...

Experimental realization of a programmable quantum-state discriminator and a phase-covariant quantum multimeter
We present an optical implementation of two programmable quantum measurement devices. The first one serves for unambiguous discrimination of two nonorthogonal states of a qubit. The particular pair of states to be discriminated is specified ...
