Calculating the squeezed bispectrum in stochastic inflation by Monte Carlo simulation
Koichi Miyamoto, Yuichiro Tada
The bispectrum of cosmological perturbations is an important probe of inflation and the underlying particle physics. However, calculating it becomes challenging in inflation models…

Calculating the power spectrum in stochastic inflation by Monte Carlo simulation and least squares curve fitting
Koichi Miyamoto, Yuichiro Tada
The stochastic- formalism is widely used to study inflation models in which the quantum diffusion of inflatons dominates the background dynamics, leading to interesti…

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
Koichi Miyamoto, Yuichiro Tada
Quantum algorithms for scientific computing and their applications have been studied actively. In this paper, we propose a quantum algorithm for estimating the first eigenvalue of…
