Shots-to-Approximate-Solution Scaling in Neutral-Atom Quantum Optimization
Junwoo Jung, Jaewook Ahn
Whether neutral-atom quantum optimization protocols exhibit genuine concentration toward low-energy solution structure remains an open question. Here, we introduce a shots-to-appro…
Quantum-Enhanced Deterministic Inference of -Independent Set Instances on Neutral Atom Arrays
Juyoung Park, Junwoo Jung, Jaewook Ahn
Noisy quantum annealing experiments on Rydberg atom arrays produce measurement outcomes that deviate from ideal distributions, complicating performance evaluation. To enable a data…
Quantum-Enhanced Simulated Annealing Using Rydberg Atoms
Seokho Jeong, Juyoung Park, Jaewook Ahn
Quantum-classical hybrid algorithms offer a promising strategy for tackling computationally challenging problems, such as the maximum independent set (MIS) problem that plays a cru…
Blinking optical tweezers for atom rearrangements
Kangjin Kim, Kangheun Kim, Jaewook Ahn
We propose and experimentally demonstrate an energy-efficient approach for holding and rearranging an N x M atom array using only N optical tweezers. This is achieved through the s…
Impact-parameter selective Rydberg atom collision by optical tweezers
Hansub Hwang, Sunhwa Hwang, Jaewook Ahn +2
Cold collisions between two Rydberg rubidium atoms (Rb) are investigated by controlling the impact parameter and collision energy. Optical tweezers are employed to hold one…
