High performance imaging of Yb atom in shallow clock-magic tweezer by alternating dual-tone narrowline cooling
Yunheung Song, Kangheun Kim, Jeong Ho Han +2
We demonstrate imaging Yb single atoms in clock-magic tweezers of 759.4 nm wavelength, with above 99.9% fidelity and survival. We use alternating dual-tone narrowline imagi…
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…
A Rydberg-atom approach to the integer factorization problem
Juyoung Park, Seokho Jeong, Minhyuk Kim +6
The task of factoring integers poses a significant challenge in modern cryptography, and quantum computing holds the potential to efficiently address this problem compared to class…
Quantum Computing Dataset of Maximum Independent Set Problem on King's Lattice of over Hundred Rydberg Atoms
Kangheun Kim, Minhyuk Kim, Juyoung Park +2
Finding the maximum independent set (MIS) of a large-size graph is a nondeterministic polynomial-time (NP)-complete problem not efficiently solvable with classical computations. He…
Rydberg-atom graphs for quadratic unconstrained binary optimization problems
Andrew Byun, Junwoo Jung, Kangheun Kim +4
There is a growing interest in harnessing the potential of the Rydberg-atom system to address complex combinatorial optimization challenges. Here we present an experimental demonst…
Realization of an extremely anisotropic Heisenberg magnet in Rydberg atom arrays
Kangheun Kim, Fan Yang, Klaus Mølmer +1
Strong mutual interactions correlate elementary excitations of quantum matter and plays a key role in a range of emergent phenomena, from binding and condensation to quantum therma…
Quantum tomography of Rydberg atom graphs by configurable ancillas
Kangheun Kim, Jaewook Ahn
Tomographic reconstruction of the many-body quantum state of a scalable qubit system is of paramount importance in quantum computing technologies. However, conventional approaches…
Rydberg Quantum Wires for Maximum Independent Set Problems with Nonplanar and High-Degree Graphs
Minhyuk Kim, Kangheun Kim, Jaeyong Hwang +2
One prominent application of near-term quantum computing devices is to solve combinatorial optimization such as non-deterministic polynomial-time hard (NP-hard) problems. Here we p…
