Coherent-disorder-driven complexity transitions in a quantum-advantage architecture
Sung-Bin B. Lee, Chae-Yeun Park, Changhun Oh +1
While decoherence is known to erode classical hardness in quantum random sampling, the impact of coherent spatial disorder remains an open question. We study a square-lattice insta…
Strictly Local Tile-Code Architectures on Two-Dimensional Planar Lattices
Yoonjin Bae, Chae-Yeun Park
Tile codes are a family of planar quantum low-density parity-check (qLDPC) codes with weight-6 stabilizers and open boundary conditions, offering an encoding efficiency of…
Toward the Goldilocks Blind Compression of Quantum States
Hyunho Cha, Chae-Yeun Park, Jungwoo Lee
Quantum autoencoders (QAEs) are learning architectures that compress quantum data into a low-dimensional latent state while preserving the information needed for reconstruction. We…
HyQuRP: Hybrid quantum-classical neural network with rotational and permutational equivariance
Semin Park, Chae-Yeun Park
Group-equivariant quantum machine learning has emerged as a promising paradigm by incorporating symmetry into quantum models. However, constructing models simultaneously equivarian…
