A bounded referenced entanglement witness

A phase-matched packet model and an explicit decoder › A bounded referenced entanglement witness · lines 1263–1273

Define

W_{λ} = (id_{R} \otimes D_{λ}^{*}) (\frac{1}{2} I_{R M} - ∣ Φ ⟩ ⟨ Φ ∣) .

This is a bounded self-adjoint operator on reference and packet, with $∥ W_{λ} ∥ \leq 1/2$ .
