A little bit of classical magic to achieve quantum speedup
Dagomir Kaszlikowski, Pawel Kurzynski
We introduce nebit, a classical bit with a signed probability distribution. We quantify its entropy using Szekely theorem on signed probability measures and show that classical sto…
Attractors and asymptotic dynamics of open discrete-time quantum walks on cycles
Adam S. Sajna, Tomasz P. Polak, Antoni Wojcik +1
Open quantum walks often lead to a classical asymptotic behavior. Here, we look for a simple open quantum walk whose asymptotic behavior can be non-classical. We consider a discret…
Pre- and post-selection paradoxes in quantum walks
Tomasz Kopyciuk, Mikolaj Lewandowski, Pawel Kurzynski
Many features of single-partite quantum walks can be simulated by classical waves. However, it was recently experimentally shown that some temporal sequences of measurements on a q…
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…
Assembly of 2N entangled fermions into multipartite composite bosons
Zakarya Lasmar, P. Alexander Bouvrie, Adam S. Sajna +2
An even number of fermions can behave in a bosonic way. The simplest scenario involves two fermions which can form a single boson. But four fermions can either behave as two bipart…
