Shortcut to Multipartite Entanglement Generation: A Graph Approach to Boson Subtractions
Seungbeom Chin, Yong-Su Kim, Marcin Karczewski
We propose a graph method for systematically searching for schemes that can generate multipartite entanglement in linear bosonic systems with heralding. While heralded entanglement…
Relative homotopy approach to topological phases in quantum walks
Andrzej Grudka, Marcin Karczewski, Pawel Kurzynski +2
Discrete-time quantum walks (DTQWs) provide a convenient platform for a realisation of many topological phases in noninteracting systems. They often offer more possibilities than s…
Avenues to generalising Bell inequalities
Marcin Karczewski, Giovanni Scala, Antonio Mandarino +2
Characterizing the set of all Bell inequalities is a notably hard task. An insightful method of solving it in case of Bell correlation inequalities for scenarios with two dichotomi…
Optimal interferometry for Bellnonclassicality by a vacuumonephoton qubit
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +2
Bell nonclassicality of a single photon superposition in two modes, often referred to as `nonlocality of a single photon', is one of the most striking nonclassical phenomena discus…
Comment on `Single particle nonlocality with completely independent reference states'
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
We comment on the purported violation of local realism, by a single photon induced correlations between homodyne detectors, which one can find in: New J. Phys. 10, 113024 (2008), […
On detecting violation of local realism with photon-number resolving weak-field homodyne measurements
Tamoghna Das, Marcin Karczewski, Antonio Mandarino +3
Non-existence of a local hidden variables (LHV) model for a phenomenon benchmarks its use in device-independent quantum protocols. Nowadays photon-number resolving weak-field homod…
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…
Borromean states in discrete-time quantum walks
Marcin Markiewicz, Marcin Karczewski, Pawel Kurzynski
In the right conditions, removing one particle from a multipartite bound state can make it fall apart. This feature, known as the "Borromean property", has been recently demonstrat…
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…
Generalized Probabilistic Description of Noninteracting Identical Particles
Marcin Karczewski, Marcin Markiewicz, Dagomir Kaszlikowski +1
We investigate an operational description of identical noninteracting particles in multiports. In particular we look for physically motivated restrictions that explain their bunchi…
How to observe duality in entanglement of two distinguishable particles?
Marcin Karczewski, Pawel Kurzynski
The entanglement between two bosons or fermions can be accessed if there exists an auxiliary degree of freedom which can be used to label and effectively distinguish the two partic…
