    • B, and which vanishes for separable states. For a pure maximally entangled state such as one of the Bell states, this quantity is strictly less than one. As shown in Eq. (5), the negativity of a pure state must be defined as in Eq. (1), in order for any pure maximally entangled state in d ⊗ d′ (d ≤ d′) quantum system to have the negativity one.
