Faster Coherent Quantum Algorithms for Phase, Energy, and Amplitude Estimation [PDF]
Quantum, 2021 We consider performing phase estimation under the following conditions: we are given only one copy of the input state, the input state does not have to be an eigenstate of the unitary, and the state must not be measured.

Real quantum amplitude estimation
EPJ Quantum Technology, 2023 AbstractWe introduce the Real Quantum Amplitude Estimation (RQAE) algorithm, an extension of Quantum Amplitude Estimation (QAE) which is sensitive to the sign of the amplitude. RQAE is an iterative algorithm which offers explicit control over the amplification policy through an adjustable parameter.

Noisy quantum amplitude estimation without noise estimation [PDF]
Physical Review A, 2022 Many quantum algorithms contain an important subroutine, the quantum amplitude estimation. As the name implies, this is essentially the parameter estimation problem and thus can be handled via the established statistical estimation theory. However, this problem has an intrinsic difficulty that the system, i.e., the real quantum computing device ...

Quantum Algorithms for Anomaly Detection Using Amplitude Estimation
SSRN Electronic Journal, 2022 Anomaly detection plays a critical role in fraud detection, health care, intrusion detection, military surveillance, etc. Anomaly detection algorithm based on density estimation (called ADDE algorithm) is one of widely used algorithms. Liang et al. proposed a quantum version of the ADDE algorithm [Phys. Rev. A 99, 052310 (2019)] and it is believed that
