Genuine multipartite entanglement as a probe of many-body localization in disordered spin chains with Dzyaloshinskii-Moriya interactions
Triyas Sapui, Keshav Das Agarwal, Tanoy Kanti Konar +2
We demonstrate that the quenched average genuine multipartite entanglement (GME) can approach its maximum value in the ergodic phase of a disordered quantum spin model. In contrast…

Measurement-based quantum computation with variable-range interacting systems
Debkanta Ghosh, Keshav Das Agarwal, Pritam Halder +1
We demonstrate that weighted graph states (WGS) generated via variable-range interacting Ising spin systems where the interaction strength decays with distance as a power law, char…
