Phase transitions in first-detection statistics of monitored long-range quantum walks
Sayan Roy, Shamik Gupta, Giovanna Morigi +1
In a quantum walk, the first-detection return probability (FDRP) characterizes salient features, determining whether the quantum walk is transient or recurrent. We study the FDRP o…
Quantization of the classical Mpemba effect
Jannis Melles, Hartmut Löwen, Benno Liebchen +4
The Mpemba effect refers to the counterintuitive phenomenon that an initially hot system can freeze faster than an initially warm one. Recent years have brought major advances in b…
Time complexity of a monitored quantum search with resetting
Emma C. King, Sayan Roy, Francesco Mattiotti +3
Searching a database is a central task in computer science and is paradigmatic of transport and optimization problems in physics. For an unstructured search, Grover's algorithm pre…
Modeling dissipation in quantum active matter
Alexander P. Antonov, Sangyun Lee, Benno Liebchen +5
Active matter is characterized by a constant influx and dissipation of energy that gives rise to directed motion. Dissipation requires interactions with an external environment, su…
Causality, localization, and universality of monitored quantum walks with long-range hopping
Sayan Roy, Shamik Gupta, Giovanna Morigi
A powerful strategy to accelerate quantum-walk-based search algorithms leverages on resetting protocols, where a detector monitors a target site and the evolution of the walker is…
Optimal spatial searches with long-range tunneling
Emma C. King, Moritz Linnebacher, Peter P. Orth +2
A quantum walk on a lattice is a paradigm of a quantum search in a database. The database qubit strings are the lattice sites, qubit rotations are tunneling events, and the target…
