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…
