Quantum gate arrays can be programmted to evaluate the expectation value of any operator

A special-purpose quantum circuit that can be programmed to evaluate the expectation value of any operator was described. Some applications of this circuit and its relation to known instances of quantum state tomography were also discussed. The circuit has a program whose state encodes the operator,...
