Quantum noise generated by local random Hamiltonians
Marcin Markiewicz, Zbigniew Puchala, Anna de Rosier +2
We investigate the impact of a local random unitary noise on multipartite quantum states of an arbitrary dimension. We follow the dynamical approach, in which the single-particle u…
Almost all quantum channels are equidistant
Ion Nechita, Zbigniew Puchała, Łukasz Pawela +1
In this work we analyze properties of generic quantum channels in the case of large system size. We use random matrix theory and free probability to show that the distance between…
Efficient simulation of sparse Markovian quantum dynamics
Andrew M. Childs, Tongyang Li
Quantum algorithms for simulating Hamiltonian dynamics have been extensively developed, but there has been much less work on quantum algorithms for simulating the dynamics of open…
Properties of quantum stochastic walks from the asymptotic scaling exponent
Krzysztof Domino, Adam Glos, Mateusz Ostaszewski +2
This work focuses on the study of quantum stochastic walks, which are a generalization of coherent, i. e. unitary quantum walks. Our main goal is to present a measure of a coherenc…
A general scheme for information interception in the ping pong protocol
Piotr Zawadzki, Jarosław Adam Miszczak
The existence of an undetectable eavesdropping of dense coded information has been already demonstrated by Pavičić for the quantum direct communication based on the ping-pong parad…
Entropy/IP: Uncovering Structure in IPv6 Addresses
Pawel Foremski, David Plonka, Arthur Berger
In this paper, we introduce Entropy/IP: a system that discovers Internet address structure based on analyses of a subset of IPv6 addresses known to be active, i.e., training data,…
