Constrained minimax approximation for quantum signal processing
Yulong Dong, James B. Larsen, Lin Lin +1
Quantum signal processing (QSP) provides a simple and efficient framework for implementing polynomial transformations using quantum circuits. Its classical design stage leads to a…

Accelerating quantum Gibbs sampling without quantum walks
Jiaqi Leng, Jiaqing Jiang, Lin Lin
Szegedy's quantum walk quadratically accelerates reversible classical Markov chains, but extending this mechanism to efficiently implementable quantum Gibbs samplers has remained c…
