Improved quantum algorithm for calculating eigenvalues of differential operators and its application to estimating the decay rate of the perturbation distribution tail in stochastic inflation

Quantum algorithms for scientific computing and their applications have been actively studied. In this paper, we propose a quantum algorithm for estimating the first eigenvalue of a differential operator L on R^{d} and its application to cosmic inflation theory. A common approach for this eigenvalue...
