Topological quantum thermometry
Anubhav Kumar Srivastava, Utso Bhattacharya, Maciej Lewenstein +1
An optimal local quantum thermometer is a quantum many-body system that saturates the fundamental lower bound for the thermal state temperature estimation accuracy [L. Correa, et.…
Synthetic dimensions for topological and quantum phases: Perspective
Javier Argüello-Luengo, Utso Bhattacharya, Alessio Celi +8
In this Perspective article we report on recent progress on studies of synthetic dimensions, mostly, but not only, based on the research realized around the Barcelona groups (ICFO,…
Enhancing quantum state tomography via resource-efficient attention-based neural networks
Adriano Macarone Palmieri, Guillem Müller-Rigat, Anubhav Kumar Srivastava +3
Resource-efficient quantum state tomography is one of the key ingredients of future quantum technologies. In this work, we propose a new tomography protocol combining standard quan…
Generation of scalable many-body Bell correlations in spin chains with short-range two-body interactions
Marcin Płodzień, Tomasz Wasak, Emilia Witkowska +2
Dynamical generation of strong and scalable quantum resources, like many-body entanglement and Bell correlations, in spin- chains, is possible with all-to-all interactions, ei…
