Spin Chain Quantum Communication on a Trapped-Ion Processor
Madhumita Sarkar, Trinity Pointon, Sougato Bose
Efficient communication between distant qubits is one of the central challenges in scaling quantum processors. Although engineered spin chain protocols have been extensively invest…
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…
Realization of a Synthetic Hall Torus with a Topological Charge Pump in 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…
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 Lenarčič +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…
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…
Scar-induced imbalance in staggered Rydberg ladders
Mainak Pal, Madhumita Sarkar, K. Sengupta +1
We demonstrate that the kinematically-constrained model of Rydberg atoms on a two-leg ladder with staggered detuning, , has quantum many-body scars (QMBS) in its spectr…
Floquet engineering of binding in doped and photo-doped Mott insulators
Madhumita Sarkar, Zala Lenarčič, Denis Golež
We investigate the emergence of bound states in chemically and photo-doped Mott insulators, mediated by spin and -pairing fluctuations within both 2-leg ladder and 2D systems. T…
