Description
I will present a lattice field theory formulation of the many-body dynamics of superconducting quantum circuits. This technique is adapted from an ab initio formulation of nuclear physics called "lattice QCD", and consists of writing quantum circuit problems as path integrals then numerically solving them. We apply the method to fluxonium, and examine the charge dispersion at high impedance and ground capacitance.
