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…
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…
Heralded Linear Optical Generation of Dicke States
Minhyeok Kang, Jaehee Kim, William J. Munro +2
Entanglement is a fundamental feature of quantum mechanics and a key resource for quantum information processing. Among multipartite entangled states, Dicke states …
Jacobi-Anger Density Estimation for Energy Distribution of Quantum States
Kyeongan Park, Gwonhak Lee, Minhyeok Kang +2
The energy distribution of a quantum state is essential for accurately estimating a molecule's ground state energy in quantum computing. Directly obtaining this distribution requir…
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…
Quadratically Shallow Quantum Circuits for Hamiltonian Functions
Youngjun Park, Minhyeok Kang, Chae-Yeun Park +1
Many quantum algorithms for ground-state preparation and energy estimation require the implementation of high-degree polynomials of a Hamiltonian to achieve better convergence rate…
Doubling Qubits in a Trapped-Ion System via Vibrational Dual-Rail Encoding
Minhyeok Kang, Wentao Chen, Hyukjoon Kwon +2
Vibrational modes of trapped ions have traditionally served as quantum buses to mediate internal qubits. However, with recent advances in quantum control, it has become possible to…
Hardware-efficient ansatz without barren plateaus in any depth
Chae-Yeun Park, Minhyeok Kang, Joonsuk Huh
Variational quantum circuits have recently gained much interest due to their relevance in real-world applications, such as combinatorial optimizations, quantum simulations, and mod…
