Parallel in time dynamics with quantum annealers
Konrad Jałowiecki, Andrzej Więckowski, Piotr Gawron +1
Recent years have witnessed an unprecedented increase in experiments and hybrid simulations involving quantum computers. In particular, quantum annealers. Although quantum supremac…
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…
Quantum image classification using principal component analysis
Mateusz Ostaszewski, Przemysław Sadowski, Piotr Gawron
We present a novel quantum algorithm for classification of images. The algorithm is constructed using principal component analysis and von Neuman quantum measurements. In order to…
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).…
Relativistic quantum pseudo-telepathy
Piotr Gawron, Łukasz Pawela
We analyze the impact of the Unruh effect on the quantum Magic Square game. We find the values of acceleration parameter for which quantum strategy yields higher players' winning p…
Generalized open quantum walks on Apollonian networks
Ł. Pawela, P. Gawron, J. A. Miszczak +1
We introduce the model of generalized open quantum walks on networks using the Transition Operation Matrices formalism. We focus our analysis on the mean first passage time and the…
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…
Enhancing pseudo-telepathy in the Magic Square game
Łukasz Pawela, Piotr Gawron, Zbigniew Puchała +1
We study the possibility of reversing an action of a quantum channel. Our principal objective is to find a specific channel that reverses as accurately as possible an action of a g…
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…
Restricted numerical shadow and geometry of quantum entanglement
Zbigniew Puchała, Jarosław Adam Miszczak, Piotr Gawron +3
The restricted numerical range of an operator acting on a -dimensional Hilbert space is defined as a set of all possible expectation values of this operator among p…
Noise effects in the quantum search algorithm from the computational complexity point of view
Piotr Gawron, Jerzy Klamka, Ryszard Winiarczyk
We analyse the resilience of the quantum search algorithm in the presence of quantum noise modelled as trace preserving completely positive maps. We study the influence of noise on…
Qubit flip game on a Heisenberg spin chain
Jarosław A. Miszczak, Piotr Gawron, Zbigniew Puchała
We study a quantum version of a penny flip game played using control parameters of the Hamiltonian in the Heisenberg model. Moreover, we extend this game by introducing auxiliary s…
Numerical shadow and geometry of quantum states
Charles F. Dunkl, Piotr Gawron, John A. Holbrook +3
The totality of normalised density matrices of order N forms a convex set Q_N in R^(N^2-1). Working with the flat geometry induced by the Hilbert-Schmidt distance we consider image…

The influence of spontaneous emission channel and generalized Pauli channel on quantum Monty Hall Game is analysed. The scheme of Flittney and Abbott is reformulated using the form…
Restricted numerical range: a versatile tool in the theory of quantum information
Piotr Gawron, Zbigniew Puchała, Jarosław Adam Miszczak +2
Numerical range of a Hermitian operator X is defined as the set of all possible expectation values of this observable among a normalized quantum state. We analyze a modification of…
