Decoherence on Staggered Quantum Walks
R. A. M. Santos, F. L. Marquezino
Decoherence phenomenon has been widely studied in different types of quantum walks. In this work we show how to model decoherence inspired by percolation on staggered quantum walks…
Quantum state transfer on the complete bipartite graph
R. A. M. Santos
Previously it was shown that (almost) perfect state transfer can be achieved on the complete bipartite graph by a discrete-time coined quantum walk based algorithm when both the se…
Lackadaisical quantum walks on 2D grids with multiple marked vertices
Nikolajs Nahimovs, Raqueline A. M. Santos
Lackadaisical quantum walk (LQW) is a quantum analog of a classical lazy walk, where each vertex has a self-loop of weight . For a regular 2D grid LQW c…
Quantum speedup for track reconstruction in particle accelerators
Duarte Magano, Akshat Kumar, Mārtiņš Kālis +10
To investigate the fundamental nature of matter and its interactions, particles are accelerated to very high energies and collided inside detectors, producing a multitude of other…
