Efficiently architecting VQAs: Expressibility--Trainability--Resources Pareto-Optimality
Rodrigo M. Sanz, Andreu Angles-Castillo, Eduard Alarcon +1
Ansatz selection is a key factor in the performance of variational quantum algorithms (VQAs). While much of the state-of-the-art still relies on heuristic choices, an inadequate ci…
Adaptive Parallelism-Aware Qubit Routing for Ion Trap QCCD Architectures
Anabel Ovide, Andreu Angles-Castillo, Carmen G. Almudever
Trapped-ion Quantum Charge-Coupled Device (QCCD) architectures promise scalability through interconnected trap zones and dynamic ion transport; however, this transport capability c…
A quantum walk simulation of extra dimensions with warped geometry
Andreu Anglés-Castillo, Armando Pérez
We investigate the properties of a quantum walk which can simulate the behavior of a spin particle in a model with an ordinary spatial dimension, and one extra dimension with…
Prethermalization of quantum systems interacting with non-equilibrium environments
Andreu Anglés-Castillo, Mari Carmen Bañuls, Armando Pérez +1
The usual paradigm of open quantum systems falls short when the environment is actually coupled to additional fields or components that drive it out of equilibrium. Here we explore…
Quantum simulation of quantum relativistic diffusion via quantum walks
Pablo Arnault, Adrian Macquet, Andreu Anglés-Castillo +6
Two models are first presented, of one-dimensional discrete-time quantum walk (DTQW) with temporal noise on the internal degree of freedom (i.e., the coin): (i) a model with both a…
