A quantum computing system includes a classical computer coupled in combination with a quantum computing system, wherein the quantum computing system is configurable to execute program instructions to process input data to generate corresponding output data. The quantum computing system is configured to execute a variational quantum amplitude estimation (VQAE) algorithm by iteratively executing a sequence of quantum operations including a maximum likelihood amplitude estimation and performing a variational approximation after an iteration to determine a variational quantum state associated with the outcome of the maximum likelihood amplitude estimation. The quantum computing system may also execute an adaptive VQAE by performing a rescaling process to reduce the variational cost of the VQAE.
