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
We study a one-dimensional frustrated spin chain, which combines cluster-Ising and anisotropic next-nearest neighbor Ising models. We first offer a historical perspective that just…
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…
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…
Quantum correlations and spatial localization in trapped one-dimensional ultra-cold Bose-Bose-Bose mixtures
Tran Duong Anh-Tai, Miguel A. García-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 María-García +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…
