Relating entropies of quantum channels
Dariusz Kurzyk, Łukasz Pawela, Zbigniew Puchała
In this work, we study two different approaches to defining the entropy of a quantum channel. One of these is based on the von Neumann entropy of the corresponding Choi-Jamiołkowsk…
QuantumInformation.jl---a Julia package for numerical computation in quantum information theory
Piotr Gawron, Dariusz Kurzyk, Łukasz Pawela
Numerical investigations are an important research tool in quantum information theory. There already exists a wide range of computational tools for quantum information theory imple…
Unconditional Security of a -State Quantum Key Distribution Protocol
Dariusz Kurzyk, Łukasz Pawela, Zbigniew Puchała
Quantum key distribution protocols constitute an important part of quantum cryptography, where the security of sensitive information arises from the laws of physics. In this paper…
Conditional entropic uncertainty relations for Tsallis entropies
Dariusz Kurzyk, Łukasz Pawela, Zbigniew Puchała
The entropic uncertainty relations are a very active field of scientific inquiry. Their applications include quantum cryptography and studies of quantum phenomena such as correlati…
Quantum inferring acausal structures and the Monty Hall problem
Dariusz Kurzyk, Adam Glos
This paper presents a quantum version of the Monty Hall problem based upon the quantum inferring acausal structures, which can be identified with generalization of Bayesian network…
Quantum Hidden Markov Models based on Transition Operation Matrices
Michał Cholewa, Piotr Gawron, Przemysław Głomb +1
In this work, we extend the idea of Quantum Markov chains [S. Gudder. Quantum Markov chains. J. Math. Phys., 49(7), 2008] in order to propose Quantum Hidden Markov Models (QHMMs).…
Decoherence effects in the quantum qubit flip game using Markovian approximation
Piotr Gawron, Dariusz Kurzyk, Łukasz Pawela
We are considering a quantum version of the penny flip game, whose implementation is influenced by the environment that causes decoherence of the system. In order to model the deco…
A model for quantum queue
Piotr Gawron, Dariusz Kurzyk, Zbigniew Puchała
We consider an extension of Discrete Time Markov Chain queueing model to the quantum domain by use of Discrete Time Quantum Markov Chain. We introduce methods for numerical analysi…
