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…
Unbiased quantum phase estimation
Xi Lu, Hongwei Lin
Quantum phase estimation algorithm (PEA) is one of the most important algorithms in early studies of quantum computation. It is also a key for many other quantum algorithms, such a…
Improved Quantum Supersampling for Quantum Ray Tracing
Xi Lu, Hongwei Lin
Ray tracing algorithm is a category of rendering algorithms that calculate the color of pixels by simulating the physical movements of a huge amount of rays and calculating their e…
