Emergence of a Macroscopic Cat State and Multi-Channel Entanglement in a Frustrated Cluster Spin Chain
Mohit Lal Bera, Andreu Anglés-Castillo, Alberto Acevedo Meléndez +8
The paper investigates a one‑dimensional frustrated spin chain that combines cluster‑Ising and anisotropic next‑nearest‑neighbor Ising interactions, revealing two distinct quantum…
Adaptive time Compressed QITE (ACQ) and its geometrical interpretation
Alberto Acevedo Meléndez, Carmen G. Almudéver, Miguel Angel Garcia-March +8
Imaginary time evolution (ITE) is a well-established method for ground-state preparation, a fundamental problem in many fields such as materials science, chemistry, and optimizatio…
Distinguishing synthetic unravelings on quantum computers
Eloy Piñol, Piotr Sierant, Dustin Keys +6
Distinct monitoring or intervention schemes can produce different conditioned stochastic quantum trajectories while sharing the same unconditional (ensemble-averaged) dynamics. Thi…
Quantum correlations and spatial localization in trapped one-dimensional ultra-cold Bose-Bose-Bose mixtures
Tran Duong Anh-Tai, Miguel A. GarcÃa-March, Thomas Busch +1
We systematically investigate and illustrate the complete ground-state phase diagram for a one-dimensional, three-species mixture of a few repulsively interacting bosons trapped ha…
Engineering impurity Bell states through coupling with a quantum bath
Tran Duong Anh-Tai, Thomás Fogarty, Sergi de MarÃa-GarcÃa +2
We theoretically demonstrate the feasibility of creating Bell states in multi-component ultra-cold atomic gases by solely using the ability to control the inter-particle interactio…
Population annealing with topological defect driven nonlocal updates for spin systems with quenched disorder
David Cirauqui, Miguel Ãngel GarcÃa-March, José Ramón MartÃnez Saavedra +2
Population Annealing, one of the currently state-of-the-art algorithms for solving spin-glass systems, sometimes finds hard disorder instances for which its equilibration quality a…
