A highly accurate DFT-based parameter estimator for complex exponentials
Journal of Telecommunications and Information Technology, 2006 A highly accurate DFT-based complex exponential parameter estimation algorithm is presented in this paper. It will be shown that for large number of samples and high signal to noise ratio (SNR), the phase estimation error variance performance is only 0 ...

Modified Grover operator for quantum amplitude estimation
New Journal of Physics, 2021 In this paper, we propose a quantum amplitude estimation method that uses a modified Grover operator and quadratically improves the estimation accuracy in the ideal case, as in the conventional one using the standard Grover operator.

An estimate of the K0-K0bar mixing amplitude [PDF]
Journal of High Energy Physics, 2001 We computed the B_K parameter on the lattice by using a non-perturbatively improved Wilson action. From our quenched simulation, in the MSbar scheme and at mu=2 GeV, we obtain B_K=0.73(7)^{+0.05}_{-0.01}. To gain some insight in the systematic errors due to the use of the quenched approximation, we also made the unquenched computation with Wilson ...

Amplitude Only Direction of Arrival Estimation
2023 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2023 In this manuscript, we present a novel hardware concept for the estimation of the direction of arrival of electro-magnetic signals. An arrangement of two patch antenna arrays, tilted with respect to each other, is used to create a monotonic relationship between the DoA and the received power difference between both arrays.

The Quantum Amplitude Estimation Algorithms on Near-Term Devices: A Practical Guide
Quantum Reports, 2023 The Quantum Amplitude Estimation (QAE) algorithm is a major quantum algorithm designed to achieve a quadratic speed-up. Until fault-tolerant quantum computing is achieved, being competitive over classical Monte Carlo (MC) remains elusive.
