Efficient Many-Body Shadow Metrology via Clifford Lensing
Sooryansh Asthana, Conan Alexander, Anubhav Kumar Srivastava +2
Quantum probes that enable enhanced exploration and characterization of complex systems are central to modern science, spanning applications from biology to astrophysics and chemic…
Infinite multiverses and where to find them?
Anubhav Kumar Srivastava, Pavel P. Popov, Guillem Müller-Rigat +1
Have you ever watched superhero movies like Spider-Man: Into the Spider-Verse? Or played games where your choices create different outcomes? What if we told you that in the real wo…
Electron Hydrodynamics: Viscosity Tensor and effects of a Magnetic field
Anubhav Srivastava, Subroto Mukerjee
Transport due to electrons in ultra-clean two dimensional systems can be hydrodynamic in nature with the momentum of the electrons being conserved in the bulk. This hydrodynamic be…
Thresholded Quantum Sensing with a Frustrated Kitaev Trimer
C. Huerta Alderete, Anubhav Kumar Srivastava, Bharath Hebbe Madhusudhana +1
We investigate the response of a Ramsey interferometric quantum sensor based on a frustrated, three-spin system (a Kitaev trimer) to a classical time-dependent field (signal). The…
Theory of Nonlinear Spectroscopy of Quantum Magnets
Anubhav Srivastava, Stefan Birnkammer, GiBaik Sim +2
Two-dimensional coherent spectroscopy (2DCS) is an established method for characterizing molecules and has been proposed in the THz regime as a new tool for probing exotic excitati…
Introduction to quantum entanglement in many-body systems
Anubhav Kumar Srivastava, Guillem Müller-Rigat, Maciej Lewenstein +1
The quantum mechanics formalism introduced new revolutionary concepts challenging our everyday perceptions. Arguably, quantum entanglement, which explains correlations that cannot…
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.…
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…
