Component-wise Validation of Amplitude Encoding within Quantum Amplitude Estimation

AlQalam Journal of Medical and Applied Sciences
Quantum Amplitude Estimation (QAE) is a fundamental component of many quantum computing algorithms and applications. The practical implementation of QAE workflows on current Noisy Intermediate-Scale Quantum (NISQ) platforms requires accurate probability amplitude representation and reliable measurement recovery. Understanding the behavior of individual

Quantum Bayes estimation of the amplitude of a coherent signal (Corresp.)

IEEE Transactions on Information Theory, 1974
The complex amplitude of a coherent quantum signal in the presence of thermal noise is to be estimated when its real and imaginary parts have a Gaussian prior distribution. Cost functions of Gaussian, power-law, and delta-function forms are shown all to lead to the same optimum estimator.
