  Quantum computers have an exponential speed-up advantage over classical
computers. One of the most prominent utilities of quantum computers is their
ability to study complex quantum systems in various fields using quantum
computational algorithms. Quantum computational algorithms can be used to study
cosmological systems and how they behave with variations in the different
parameters of the system. Here, we use the variational quantum eigensolver
(VQE) algorithm to simulate the Hawking radiation phenomenon. VQE algorithm is
a combination of quantum and classical computation methods used to obtain the
minimum energy eigenvalue for a given Hamiltonian. Three different custom
ansatzes are used in the VQE algorithm from which the results for the case with
minimum errors are studied. We obtain the plots for temperature and power from
the minimum energy eigenvalue recorded for different values of mass and
distance from the center of the black hole. The final result is then analyzed
and compared against already existing data on Hawking radiation.
