Description

The zeta-regularization allows to establish a
connection between Feynman’s path
integral and Fourier integral operator
zeta-functions. This fact can be utilized to perform a
regularization of vacuum expectation values in quantum field theories.
In this talk, we will describe the concept of this
zeta-regularization, give a simple example and demonstrate
that quantum computing can be employed to numerically evaluate
zeta-regulated vacuum expectation values.
