Implementation of generalized measurements with minimal disturbance on a quantum computer
Thomas Decker, Markus Grassl · Fortschritte der Physik · 2006
Abstract We consider the problem of efficiently implementing a generalized measurement on a quantum computer. Using methods from representation theory, we exploit symmetries of the states we want to identify respectively symmetries of the measurement operators. In order to allow the information to be extracted sequentially, the disturbance of the quantum state due to the measurement should be minimal.
