Reviewing pigeonhole effect with transversal modes
Marcin Wieśniak
We investigate the interference setup claimed to reveal the quantum pigeonhole effect. It is a claim that it is possible that three parties travel across a two-path interferometer,…
Symmetrized persistency of Bell correlations for Dicke states and GHZ-based mixtures: studying the limits of monogamy
Marcin Wieśniak
Quantum correlations, in particular those, which enable to violate a Bell inequality \cite{BELL}, open a way to advantage in certain communication tasks. However, the main difficul…
Distance between Bound Entangled States from Unextendible Product Bases and Separable States
Marcin Wieśniak, Palash Pandya, Omer Sakarya +1
We discuss the use of the Gilbert algorithm to tailor entanglement witnesses for unextendibleproduct basis bound entangled states (UPB BE states). The method relies on the fact tha…
Quantum secure learning with classical samples
Wooyeong Song, Youngrong Lim, Hyukjoon Kwon +5
Studies addressing the question "Can a learner complete the learning securely?" have recently been spurred from the standpoints of fundamental theory and potential applications. In…
Hilbert-Schmidt distance and entanglement witnessing
Palash Pandya, Omer Sakarya, Marcin Wieśniak
Gilbert proposed an algorithm for bounding the distance between a given point and a convex set. In this article we apply the Gilbert's algorithm to get an upper bound on the Hilber…
Comment on "Experimental retrodiction of trajectories in double interferometer"
Marcin Wieśniak
A comment on a misleading statement contained in [Phys. Rev. A 97, 062115 (2018)]. v2: a typo corrected
Spectra in nested Mach-Zehnder interferometer experiments
Marcin Wieśniak
By the means of the standard quantum mechanics formalism I present an explicit derivation of the structure of power spectra in Danan {\em et al.} and Zhou {\em et al.} experiments…
Entanglement conditions involving intensity correlations of optical fields: the case of multi-port interferometry
Junghee Ryu, Marcin Marciniak, Marcin Wieśniak +2
Normalized quantum Stokes operators introduced in [Phys. Rev. A {\bf 95}, 042113 (2017)] enable one to better observe non-classical correlations of entangled states of optical fiel…
Subadditivity of logarithm of violation of geometric Bell inequalities for qudits
Marcin Wieśniak, Palash Pandya
Geometrical Bell Inequalities (GBIs) are the strongest known Bell inequalities for collections of qubits. However, their generalizations to other systems is not yet fully understoo…
The entire history of a photon
Marcin Wieśniak
Using the most basic mathematical tools, I present the full analysis of the experiment decribed in [A. Danan, D. Farfurnik, S. Bar-Ad, and L. Vaidman, {\em Phys. Rev. Lett.} {\bf 1…
Clearer visibility Hong-Ou-Mandel effect with correlation function based on rates rather than intensities
Krzysztof Rosołek, Kamil Kostrzewa, Arijit Dutta +3
We test ideas put forward e.g in arXiv:1508.02368, which suggest that using rates in quantum optics can lead to better indicators of non-classicality for states of quantum optical…
Quadratic Entanglement Criteria for Qutrits
Krzysztof Rosołek, Marcin Wieśniak, Lukas Knips
The problem of detecting non-classical correlations of states of many qudits is incomparably more involved than in a case of qubits. The reason is that for qubits we have a conveni…
Geometrical Bell inequalities for arbitrarily many qudits with different outcome strategies
Marcin Wieśniak, Arijit Dutta, Junghee Ryu
Greenberger-Horne-Zeilinger states are intuitively known to be the most non-classical ones. They lead to the most radically nonclassical behavior of three or more entangled quantum…
Package of facts and theorems for efficiently generating entanglement criteria for many qubits
Marcin Wieśniak, Koji Maruyama
We present a package of mathematical theorems, which allow to construct multipartite entanglement criteria. Importantly, establishing bounds for certain classes of entanglement doe…
Theoretical Falsification of Leggett Conjecture for Two Qubits or One Ququat
Marcin Wieśniak
Recently, some attention has been paid to falsifying the Leggett model, in which global probabilities characterizing a quantum state are represented by a combination of factorisabl…
Decoherence through Spin Chains: Toy Model
Marcin Wieśniak
The description of the dynamics of closed quantum systems, governed by the Schroedinger equation at first sight seems incompatible with the Lindblad equation describing open ones.…
