A single-photon-based receiver-device-independent QSDC protocol is proposed, with claimed efficiency and distance advantages over DI QSDC, but the security proof is incomplete.
In this way, Alice’s measurements are generated with the form of M bi = |ψbi ⟩⟨ψbi | = cos2 θ|0⟩⟨0| + e −i2πbi n sin θ cos θ|0⟩⟨1| + e i2πbi n sin θ cos θ|1⟩⟨0| + sin2 θ|1⟩⟨1|
