Hybrid quantum gap estimation algorithm using a filtered time series
Woo-Ram Lee, Ryan Scott, V. W. Scarola
Quantum simulation advantage over classical memory limitations would allow compact quantum circuits to yield insight into intractable quantum many-body problems, but the interrelat…
Measurement-Based Time Evolution for Quantum Simulation of Fermionic Systems
Woo-Ram Lee, Zhangjie Qin, Robert Raussendorf +2
Quantum simulation using time evolution in phase estimation-based quantum algorithms can yield unbiased solutions of classically intractable models. However, long runtimes open suc…
Quantum annealing of Cayley-tree Ising spins at small scales
Yunheung Song, Minhyuk Kim, Hansub Hwang +2
Significant efforts are being directed towards developing a quantum annealer capable of solving combinatorial optimization problems. The challenges are Hamiltonian programming and…
Coherent and dissipative dynamics of entangled few-body systems of Rydberg atoms
Woojun Lee, Minhyuk Kim, Hanlae Jo +2
Experimentally observed quantum few-body dynamics of neutral atoms excited to a Rydberg state are numerically analyzed with Lindblad master equation formalism. For this, up to five…
Defect-free atomic array formation using Hungarian matching algorithm
Woojun Lee, Hyosub Kim, Jaewook Ahn
Deterministic loading of single atoms onto arbitrary two-dimensional lattice points has recently been demonstrated, where by dynamically controlling the optical-dipole potential, a…
In situ single-atom array synthesis by dynamic holographic optical tweezers
Hyosub Kim, Woojun Lee, Han-gyeol Lee +3
Cooling and trapping of atoms by light has enabled one to build and manipulate quantum systems at the single atom level. Such a bottom-up approach becomes one of the fascinating ch…
Coherent Control of Resonant Two-Photon Transitions by Counter-Propagating Ultrashort Pulse Pairs
Woojun Lee, Hyosub Kim, Kyungtae Kim +1
We describe optimized coherent control methods for two-photon transitions in atoms of a ladder-type three-state energy configuration. Our approach is based on the spatial coherent…
