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…
Fast and reliable atom transport by optical tweezers
Sunhwa Hwang, Hansub Hwang, Kangjin Kim +4
Movable single atoms have drawn significant attention for their potentials as flying quantum memory in non-local, dynamic quantum computing architectures. However, when dynamic opt…
Programming higher-order interactions of Rydberg atoms
Andrew Byun, Seokho Jeong, Jaewook Ahn
Higher-order interactions in spin-based Hamiltonians are crucial in addressing numerous fundamentally significant physical problems. In this work, Rydberg-atom graph gadgets are in…
