Simultaneous cooling of qubits via a quantum absorption refrigerator and beyond
Jithin G. Krishnan, Chandrima B. Pushpan, Amit Kumar Pal
We design a quantum thermal device that can simultaneously and dynamically cool multiple target qubits. Using a setup with three bosonic heat baths, we propose an engineering of in…
Scalable and deterministic Greenberger-Horne-Zeilinger state generation via graph states-assisted measurements
Harikrishnan K J, Amit Kumar Pal
We propose a scalable and deterministic protocol for growing large multi-qubit states starting from two-qubit non-maximally entangled pure states, where the bipartite entanglement…
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…
Entanglement and fidelity across quantum phase transitions in locally perturbed topological codes with open boundaries
Harikrishnan K J, Amit Kumar Pal
We investigate the topological-to-non-topological quantum phase transitions (QPTs) occurring in the Kitaev code under local perturbations in the form of local magnetic field and sp…
