Floquet driven long-range interactions induce super-extensive scaling in quantum batteries
Stavya Puri, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Achieving quantum advantage in energy storage and power extraction is a primary objective in the design of quantum-based batteries. We explore how long-range (LR) interactions in c…
More nonlocality with less incompatibility in higher dimensions: Bell vs prepare-measure scenarios
Sudipta Mondal, Pritam Halder, Saptarshi Roy +1
Connecting incompatibility in measurements with the violation of local realism is one of the fundamental avenues of research. For two qubits, any incompatible pair of projective me…
Measurement-based qudit quantum refrigerator with subspace cooling
Debkanta Ghosh, Tanoy Kanti Konar, Aditi Sen De
We develop a method to transform a collection of higher-dimensional spin systems from the thermal state with a very high temperature of a local spin-s Hamiltonian to a low-lying en…
Creating two-qudit maximally entangled quantum link through bulk
Keshav Das Agarwal, Sudip Kumar Haldar, Aditi Sen De
We design a setup for creating almost maximally entangled two-qudit link between distant nodes which are weakly coupled with the interacting spin-s bulk (processor). We exhibit tha…
Slow decay rate of correlations induced by long-range extended Dzyaloshinskii-Moriya interactions
Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju, Aditi Sen De
We examine the impact of long-range Dzyaloshinskii-Moriya (DM) interaction in the extended model on the phase diagram as well as the static and dynamical properties of quantum…
Recovery of resources through sequential noisy measurements
Sudipta Mondal, Pritam Halder, Amit Kumar Pal +1
Noisy unsharp measurements incorporated in quantum information protocols may hinder performance, reducing the quantum advantage. However, we show that, unlike projective measuremen…
Discovering Factorization Surface of Quantum Spin Chains with Machine Learning
Nakul Aggarwal, Keshav Das Agarwal, Tanoy Kanti Konar +2
Entanglement in quantum many-body systems is required for a variety of quantum information tasks, making it crucial to identify the parameter space in which the ground state is ful…
Deciding factor for detecting a particle within a subspace via dark and bright states
Aashay Pandharpatte, Pritam Halder, Aditi Sen De
In a measurement-induced continuous-time quantum walk, we address the problem of detecting a particle in a subspace, instead of a fixed position. In this configuration, we develop…
Dimensional gain in sensing through higher-dimensional quantum spin chain
Shivansh Singh, Leela Ganesh Chandra Lakkaraju, Srijon Ghosh +1
Recent breakthroughs in quantum technology pave the way for extensive utilization of higher-dimensional quantum systems, which outperform their qubit counterparts in terms of capab…
Imperfect Entangling Power of Quantum Gates
Sudipta Mondal, Samir Kumar Hazra, Aditi Sen De
Achieving perfect control over the parameters defining a quantum gate is, in general, a very challenging task, and at the same time, environmental interactions can introduce distur…
