Spin Chain Quantum Communication on a Trapped-Ion Processor
Madhumita Sarkar, Trinity Pointon, Sougato Bose
The authors experimentally implement spin‑chain quantum communication protocols on a trapped‑ion processor, showing that engineered coupling profiles improve state‑transfer fidelit…
All-Electric Quantum State Transfer via Spin-Orbit Phase Matching
Madhumita Sarkar, Roopayan Ghosh, Charles G. Smith +2
Semiconductor hole-spin qubits offer a promising route to quantum computation due to their weak hyperfine interaction, and strong intrinsic spin-orbit coupling enabling electric co…
Harmonic Control of Dynamical Freezing in Programmable Rydberg Atom Arrays
Madhumita Sarkar, Ben Zindorf, Bhaskar Mukherjee +2
Periodic driving enables the engineering of complex quantum matter, yet in interacting systems it generically leads to energy absorption, which limits the lifetime of the engineere…
Doublon-Holon Pairing State in Photodoped Mott Insulators
Ryota Ueda, Madhumita Sarkar, Zala LenarÄiÄ +3
We demonstrate the existence of an unconventional pairing state in photodoped Mott insulators on ladder and quasi-two-dimensional geometries, characterized by quasi-long-range doub…
Realization of a Synthetic Hall Torus with a Spinor Bose-Einstein Condensate
T. -H. Chien, S. -C. Wu, Y. -H. Su +5
We report the first experimental realization of a synthetic Hall torus using a spinor Bose-Einstein condensate confined in a ring-shaped trap with in situ imaging. By cyclically co…
Re-entrant localization induced by short-range hopping in the fractal Rosenzweig-Porter Model
Roopayan Ghosh, Madhumita Sarkar, Ivan M. Khaymovich
Typically, metallic systems localized under strong disorder exhibit a transition to \imk{delocalization} %finite conduction as kinetic terms increase. In this work, we reveal the o…
