Self-Attention for Quantum Entanglement Prediction
Anuj Gore, Roopayan Ghosh, Dylan Lewis +1
Quantum entanglement is a powerful resource for quantum-enhanced technologies. However, its reliable quantification remains challenging due to the exponential scaling of the Hilber…
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…
Enhancement of quantum annealing via n-local catalysts
Roopayan Ghosh, Luca A. Nutricati, Natasha Feinstein +2
The potential quantum speedup in solving optimization problems via adiabatic quantum annealing is often hindered by the closing of the energy gap during the anneal, especially when…
Exponentially-enhanced quantum sensing with many-body phase transitions
Saubhik Sarkar, Abolfazl Bayat, Sougato Bose +1
Quantum sensors based on critical many-body systems are known to exhibit enhanced sensing capability. Such enhancements typically scale algebraically with the probe size. Going bey…
Quantum Liang Information Flow Probe of Causality across Critical Points
Roopayan Ghosh, Bin Yi, Sougato Bose
Investigating causation in the quantum domain is crucial. Despite numerous studies of correlations in quantum many-body systems, causation, which is very distinct from correlations…
