Two-qubit entangling gates allow the realization of new types of generalized quantum measurement, We discuss, and use photonic systems to demonstrate, two instances of this: two-qubit entangling measurements realizing superior discrimination of locally prepared two-qubit quantum states relative to what is achievable with local measurements' and classical communication; and nondestructive weak measurements with postselection, leading to quantum weak values.
