Asymptotically Optimal Quantum Amplitude Estimation by Generalized Qubitization
Xi Lu, Hongwei Lin
We first show that the standard deviation error of quantum amplitude estimation is asymptotically lower bounded by approximately , where is the number of queries.…

Random-depth Quantum Amplitude Estimation
Xi Lu, Hongwei Lin
The maximum likelihood amplitude estimation algorithm (MLAE) is a practical solution to the quantum amplitude estimation problem with Heisenberg limit error convergence. We improve…
