Scalability and performance metrics for boson sampling devices
Dong-Gil Im, Chung-Hyun Lee, Joonsuk Huh +1
Linear-optical platforms provide a promising route to demonstrate quantum computational advantage, particularly through the boson sampling problem. While a boson sampling system sh…
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…
Algorithmic Design of Heralded Linear Optical Circuits for Multipartite Entanglement
Jaehee Kim, Hon Wai Lau, William J. Munro +2
Heralded multipartite entanglement is a key resource for various quantum information tasks. However, designing linear optical circuits that generate specific target states is gener…
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…
Finite Imaginary-Time Evolution for Polynomial Unconstrained Binary Optimization
Jaehee Kim, Juhyeon Kim, Gwonhak Lee +4
Imaginary-time evolution is a standard primitive for ground-state preparation but is nonunitary, precluding direct quantum implementation. We develop Finite Imaginary-Time Evolutio…
Quantum Circuit Representation of Combinatorial Matrix Functions
Minhyeok Kang, Gwonhak Lee, Youngrong Lim +1
Permanents, hafnians, and loop-hafnians are combinatorial matrix functions closely related to perfect matchings in graphs. These matrix functions arise in the quantum amplitudes of…
