Charge readout electronics for the DUNE horizontal drift far detector: design and performance in ProtoDUNE-HD
DUNE Collaboration, S. Abbaslu, F. Abd Alrahman +1364
DUNE (Deep Underground Neutrino Experiment) is a long-baseline neutrino oscillation experiment currently under construction, whose far detectors will be the largest liquid argon ti…
Barenco gate implementation using driven two- and three-qubit spin chains
Rafael Vieira, Edgard P. M. Amorim
We propose a protocol for implementing Barenco-type multi-qubit controlled gates using short driven spin chains. Starting from an Ising interaction with a transverse drive on the l…
Parrondo-type enhancement of quantum-state transfer in spin chains
Rafael Vieira, Edgard P. M. Amorim
Spin chains have been widely studied as quantum channels for short-distance communication in quantum devices, where many-body dynamics can mediate quantum-state transfer between di…
Absorption-based qubit estimation in discrete-time quantum walks
Edgard P. M. Amorim, Lorena R. Cerutti, O. P. de Sá Neto +1
We investigate state estimation in discrete-time quantum walks with a single absorbing boundary. Using a spectral approach, we obtain closed expressions for the escape probability…
Screening in the Heitler-London Model: Revisiting the Bonding and Antibonding States of the Hydrogen Molecule
Washington P. da Silva, Daniel Vieira, Jonas Maziero +1
The present manuscript revisits one of the earliest approaches to treating molecular systems within the Schrödinger formalism of quantum mechanics: the Heitler-London (HL) model. O…
Continuous-time quantum walks on a defective lattice: Boosting the spreading of delocalized states through Parrondo's strategy
João V. Cordeiro, Eduardo I. Duzzioni, Edgard P. M. Amorim
We investigate the quantum transport of delocalized states in continuous-time quantum walks (CTQWs) on a one-dimensional lattice containing a single defect. The defect is modeled b…
Control of vertex probability via edge-weight modulation in continuous-time quantum walks
Rafael Vieira, Edgard P. M. Amorim
Continuous-time quantum walks (CTQWs) provide a versatile framework for exploring quantum transport on graphs. In this work, we investigate how the introduction of edge-weight modu…
High-fidelity state transfer via quantum walks from delocalized states
João P. Engster, Rafael Vieira, Eduardo I. Duzzioni +1
We study the state transfer through quantum walks placed on a bounded one-dimensional path. We first consider continuous-time quantum walks from a Gaussian state. We find such a st…
Localization in Quantum Walks with a Single Lattice Defect: A Comparative Study
Laurita I. da S. Teles, Edgard P. M. Amorim
We study how a single lattice defect in a discrete time quantum walk affects the return probability of a quantum particle. This defect at the starting position is modeled by a quan…
