Revealing effects of local dimension on variable-range interacting model by connecting Lieb-Robinson bounds and multipartite entanglement
Keshav Das Agarwal, Debkanta Ghosh, Pritam Halder +1
A spin- variable-range interacting Ising model may display qualitatively different behaviors depending on the fall-off rate of the interactions, as already seen in equilibrium s…
Quantum resources in Harrow-Hassidim-Lloyd algorithm
Pradeep Kumar, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Quantum algorithms have the ability to reduce runtime for executing tasks beyond the capabilities of classical algorithms. Therefore, identifying the resources responsible for quan…
Entanglement of weighted graphs uncovers transitions in variable-range interacting models
Debkanta Ghosh, Keshav Das Agarwal, Pritam Halder +1
The cluster state acquired by evolving the nearest-neighbor (NN) Ising model from a completely separable state is the resource for measurement-based quantum computation. Instead of…
Hybrid nonlocality via atom photon interactions with and without impurities
Pritam Halder, Ratul Banerjee, Saptarshi Roy +1
To obtain Bell statistics from hybrid systems composed of finite- and infinite-dimensional systems, we propose a hybrid measurement scheme, in which the continuous mode is measured…
