Claim 14:
15. A computer program product facilitating a quantum state preparation of a probability distribution process to perform amplitude estimation, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
use, by the processor, a context-aware distribution loading scheme to load arbitrary random distributions to facilitate preparing a quantum state of a probability distribution based on a structure of a quantum amplitude estimation algorithm;
construct, by the processor, a quantum operator for stochastic processes based on the quantum state to perform quantum amplitude estimation;
wherein the stochastic process is given by an initial probability distribution and transition probabilities and the probability distribution is a joint probability distribution that is a function of the initial probability distribution and the transitional probabilities, and
wherein the quantum state corresponds to the joint probability distribution to facilitate exploitation of the quantum amplitude estimation; and

adjust, by the processor, Grover oracles in the quantum amplitude estimation to employ a defined number of a plurality of objective qubits.
