an observable whose expectation value is nonnegative for all separable states, so a negative measured value certifies entanglement.

In quantum information science, entanglement witness refers to an observable whose expectation value is nonnegative for all separable states, so a negative measured value certifies entanglement. This meaning comes from Terhal (2000) in Physics Letters A.[1]
