Spread complexity as a probe in generalized and long-range Aubry-Andre-Harper models
Triyas Sapui, Tanoy Kanti Konar, Subinay Dasgupta +1
We investigate the spread complexity of quantum quenches in generalized and long-range Aubry-Andre-Harper (AAH) models, encompassing regimes with and without mobility edges. In par…
Journey in quantum metrology and sensing from foundations to applications: a review
Priya Ghosh, Tanoy Kanti Konar, Debraj Rakshit +2
We present a review on quantum metrology and sensing, from its foundations to current applications. Highlights of the review include consideration of both frequentist and Bayesian…
Interplay of Nonstabilizerness and Ergotropy in Quantum Batteries
Tanoy Kanti Konar, Jakub Zakrzewski
Nonstabilizerness plays an essential role in an efficient simulation of quantum systems on quantum computers. In this work, we investigate its role in the context of quantum batter…
Quantum-enhanced sensing from the interplay of long-range interactions and non-Hermiticity
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Long-range (LR) quantum spin systems offer promising advantages for quantum information processing and sensing. Here, we investigate parameter estimation in an long-range XX spin m…
Ergotropic Mpemba crossings in finite-dimensional quantum batteries
Triyas Sapui, Tanoy Kanti Konar, Aditi Sen De
The quantum Mpemba effect is a counterintuitive phenomenon in which a state initially farther from equilibrium relaxes more rapidly than one that starts nearer to equilibrium. In t…
Quantum error correction via purification using a single auxiliary
Chandrima B. Pushpan, Tanoy Kanti Konar, Aditi Sen De +1
We propose a single auxiliary-assisted purification-based framework for quantum error correction, capable of correcting errors that drive a system from its ground-state subspace in…
