Efficient linear optical generation of a multipartite W state
Pawel Blasiak, Ewa Borsuk, Marcin Markiewicz +1
A novel scheme is presented for generation of a multipartite W state for arbitrary number of qubits. Based on a recent proposal of entanglement without touching, it serves to demon…
Can single photon excitation of two spatially separated modes lead to a violation of Bell inequality via homodyne measurements?
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We reconsider the all-optical homodyne-measurement based experimental schemes that aim to reveal Bell nonclassicality of a single photon, often termed `nonlocality'. We focus on th…
No-go for device independent protocols with Tan-Walls-Collett `nonlocality of a single photon'
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We investigate the interferometric scheme put forward by Tan, Walls and Collett [Phys. Rev. Lett. {\bf 66}, 256 (1991)] that aims to reveal Bell non-classicality of a single photon…
