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…
Sculpting out quantum correlations with bosonic subtraction
Marcin Karczewski, Su-Yong Lee, Junghee Ryu +3
We present a method to extract M-partie bosonic correlations from an N-partite maximally symmetric state (M < N) with the help of successive applications of single-boson subtractio…
Genuine multipartite indistinguishability and its detection via generalized Hong-Ou-Mandel effect
Marcin Karczewski, Robert Pisarczyk, Paweł Kurzyński
The question whether two indistinguishable particles are bosons or fermions can be answered by observing the Hong-Ou-Mandel effect on a beam splitter. However, already for three pa…
Monogamy of particle statistics in tripartite systems simulating bosons and fermions
Marcin Karczewski, Dagomir Kaszlikowski, Pawel Kurzynski
In the quantum world correlations can take form of entanglement which is known to be monogamous. In this work we show that another type of correlations, indistinguishability, is al…
