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,…
Unraveling Multifractality and Mobility Edges in Quasiperiodic Aubry-André-Harper Chains through High-Harmonic Generation
Marlena Dziurawiec, Jessica O. de Almeida, Mohit Lal Bera +5
Quasicrystals are fascinating and important because of their unconventional atomic arrangements, which challenge traditional notions of crystalline structures. Unlike regular cryst…
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…
