Asymptotically Optimal Circuit Depth for Diagonal Unitary Synthesis and Compilation on Two-Dimensional Grids
Chengzhuo Xu, Xiao Chen, Zhihao Liu +1
Diagonal unitaries are a fundamental but resource-intensive class of quantum operations, arising as the phase separators of QAOA and the time-evolution blocks of Hamiltonian simula…

A Unified Framework for Optimizing Uniformly Controlled Structures in Quantum Circuits
Chengzhuo Xu, Xiao Chen, Xi Li +2
Quantum unitaries of the form are ubiquitous in quantum algorithms. This class encompasses not only standard uniformly controlled gates (UCGs) bu…
