Block entanglement bounds distribution of regionally localized entanglement
Jithin G. Krishnan, Aditi Sen De, Amit Kumar Pal
In quantum networks, eliminating connections between nodes is crucial to mitigate the effects of decoherence, often achieved by performing measurements on nodes that are idle, or v…

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…

Logarithmic growth of peripheral entanglement concentrated via noisy measurements in a star network of spins
Jithin G. Krishnan, Harikrishnan K. J., Amit Kumar Pal
In a star-network of qubits interacting via Heisenberg interaction of XYZ-type, we demonstrate a logarithmic growth of the localizable bipartite peripheral entanglement with increa…
