Constraint-Aware Quantum Optimization via Hamming Weight Operators
Yajie Hao, Qiming Ding, Xiao Yuan +1
Constrained combinatorial optimization with strict linear constraints underpins applications in drug discovery, power grids, logistics, and finance, yet remains computationally dem…
Obtaining Accurate Ground-State Properties on Near-term Quantum Devices
Qi-Ming Ding, Jiawei Peng, Junxiang Huang +6
Accurate ground-state calculations on noisy quantum computers are fundamentally limited by restricted ansatz expressivity and unavoidable hardware errors. We introduce a hybrid-qua…
