State Preparation Protocols for Entangled States via Open Quantum Walks
Pedro Linck, Nadja K. Bernardes
Open quantum walks couple transitions on a graph to quantum operations on an internal degree of freedom. We use this structure to formulate protocols for quantum state preparation…
Dissipative realization of a quantum distance-based classifier using open quantum walks
Pedro Linck, Graeme Pleasance, Francesco Petruccione +1
Open quantum walks (OQWs) constitute a class of quantum walks whose dynamics are entirely driven by interactions with the environment. It is well known that OQWs provide a general…
Effective Transition from Weak to Essential Non-Markovianity Induced by Coarse-Graining
Gabriel M. Arantes, Barbara Amaral, Nadja K. Bernardes
Quantum channels generally reduce the distinguishability of quantum states, thereby constraining information transmission and processing in open quantum systems. While it is known…
Thermodynamics of linear open quantum walks
Pedro Linck, Nadja Kolb Bernardes
Open quantum systems interact with their environment, leading to nonunitary dynamics. We investigate the thermodynamics of linear Open Quantum Walks (OQWs), a class of quantum walk…
Divide-and-Conquer Simulation of Open Quantum Systems
Thiago Melo D. Azevedo, Caio Almeida, Pedro Linck +2
One of the promises of quantum computing is to simulate physical systems efficiently. However, the simulation of open quantum systems - where interactions with the environment play…
Dynamics and computation in linear open quantum walks
Pedro Linck, Nadja K. Bernardes
Open Quantum Walks (OQW) are a type of quantum walk governed by the system's interaction with its environment. We explore the time evolution and the limit behavior of the OQW frame…
