Decoupling Spectral Gaps from Entanglement Complexity in Quantum Annealing
Roopayan Ghosh, Sougato Bose
Exponentially small spectral gaps are the central obstacle to adiabatic quantum annealing, yet whether such bottlenecks demand correspondingly complex entanglement remains unclear.…
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…
Gadgets for simulating a non-native interaction in quantum annealing
Robert J. Banks, Natasha Feinstein, Roopayan Ghosh +2
In certain scenarios, quantum annealing can be made more efficient by additional interactions. It has been shown that the additional interactions can reduce the scaling of per…
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…
