Quantum survival in hybrid pursuit dynamics - a lion chasing a lamb problem
P. Held, İ. Yalçınkaya, F. Pegoraro +10
Measurement and classical randomness usually degrade coherence; controlling where and when a subsystem is monitored can instead make them a tunable resource. We introduce a photoni…
Recurrence in discrete-time quantum stochastic walks
Martin Stefanak, Vaclav Potocek, Iskender Yalcinkaya +2
Interplay between quantum interference and classical randomness can enhance performance of various quantum information tasks. In the present paper we analyze recurrence phenomena i…
Quantum state identification of qutrits via a nonlinear protocol
P. V. Pyshkin, A. Gábris, O. Kálmán +2
We propose a probabilistic quantum protocol to realize a nonlinear transformation of qutrit states, which by iterative applications on ensembles can be used to distinguish two type…
Probing Measurement Induced Effects in Quantum Walks via Recurrence
Thomas Nitsche, Sonja Barkhofen, Regina Kruse +7
Measurements on a quantum particle unavoidably affect its state, since the otherwise unitary evolution of the system is interrupted by a non-unitary projection operation. In order…
Measuring Topological Invariants in Disordered Discrete Time Quantum Walks
Sonja Barkhofen, Thomas Nitsche, Fabian Elster +4
Quantum walks constitute a versatile platform for simulating transport phenomena on discrete graphs including topological material properties while providing a high control over th…
Quantum walk coherences on a dynamical percolation graph
Fabian Elster, Sonja Barkhofen, Thomas Nitsche +4
Coherent evolution governs the behaviour of all quantum systems, but in nature it is often subjected to influence of a classical environment. For analysing quantum transport phenom…
