Phys. Rev. A 72, 064306 (2005) [3 pages]Single-particle entanglementReceived 9 August 2005; published 29 December 2005 I give a simple argument that demonstrates that the state ∣0⟩∣1⟩+∣1⟩∣0⟩, with ∣0⟩ denoting a state with 0 particles (or photons) and ∣1⟩ a one-particle state, is entangled in spite of recent claims to the contrary. I also discuss viewpoints on the old controversy about whether the above state can be said to display single-particle or single-photon nonlocality. © 2005 The American Physical Society URL:
