Oscillator-Qubit Primitives for a Molecular Quantum Dynamics Simulator
Jungsoo Hong, Joonsuk Huh
Molecular quantum dynamics simulations that treat both electrons and nuclei quantum mechanically are crucial for predicting chemical reactions. With classical computation, a full w…
Efficient Multi-Controlled Gate Implementation in Trapped-Ion Systems
Minhyeok Kang, Taejin Kim, Jungsoo Hong +1
Multi-controlled gates are essential primitives in quantum algorithms, yet implementing them via standard gate-level decompositions remains resource-intensive. We develop efficient…
Oscillator-qubit generalized quantum signal processing for vibronic models: a case study of uracil cation
Jungsoo Hong, Seong Ho Kim, Seung Kyu Min +1
Hybrid oscillator-qubit processors have recently demonstrated high-fidelity control of both continuous- and discrete-variable information processing. However, most of the quantum a…
Filtered Quantum Phase Estimation
Gwonhak Lee, Minhyeok Kang, Jungsoo Hong +2
Accurate state preparation is a critical bottleneck in many quantum algorithms, particularly those for ground-state energy estimation. Even in fault-tolerant quantum computing, pre…
