Analysis of patent activity in the field of quantum information processing
Ryszard Winiarczyk, Piotr Gawron, Jarosław Adam Miszczak +2
This paper provides an analysis of patent activity in the field of quantum information processing. Data from the PatentScope database from the years 1993-2011 was used. In order to…
Collectibility for Mixed Quantum States
Łukasz Rudnicki, Zbigniew Puchała, Paweł Horodecki +1
Bounds analogous to entropic uncertainty relations allow one to design practical tests to detect quantum entanglement by a collective measurement performed on several copies of the…
Constructive entanglement test from triangle inequality
Łukasz Rudnicki, Zbigniew Puchała, Paweł Horodecki +1
We derive a simple lower bound on the geometric measure of entanglement for mixed quantum states in the case of a general multipartite system. The main ingredient of the presented…
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…
Entropic trade-off relations for quantum operations
Wojciech Roga, Zbigniew Puchała, Łukasz Rudnicki +1
Spectral properties of an arbitrary matrix can be characterized by the entropy of its rescaled singular values. Any quantum operation can be described by the associated dynamical m…
