Kerr-type nonlinear baths enhance cooling in quantum refrigerators
Tanaya Ray, Sayan Mondal, Aparajita Bhattacharyya +3
We study the self-contained three-qubit quantum refrigerator, with a three-body interaction enabling cooling of the target qubit, in presence of baths composed of anharmonic quantu…
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,…
Localization with non-Hermitian off-diagonal disorder
Aitijhya Saha, Debraj Rakshit
In this work, we discuss a non-Hermitian system described via a one-dimensional single-particle tight-binding model, where the non-Hermiticity is governed by random nearest-neighbo…
Localization Driven Quantum Sensing
Ayan Sahoo, Utkarsh Mishra, Debraj Rakshit
We show that the delocalization-localization transition in a quantum-many body (QMB) systems is a compelling quantum resource for achieving quantum-enhanced sensitivity in paramete…
Optimal quantum resource generation in coupled transmons immersed in Markovian baths
Tanaya Ray, Ahana Ghoshal, Debraj Rakshit +1
We analyze the quantum resource generation of capacitively-coupled multilevel transmon circuits surrounded by bosonic baths, within the Markovian limit. In practice, the supercondu…
