- Abstract: We demonstrate how quantum field theory problems can be embedded on quantum
annealers. The general method we use is a discretisation of the field theory
problem into a general Ising model, with the continuous field values being
encoded into Ising spin chains. To illustrate the method, and as a simple proof
of principle, we use a (hybrid) quantum annealer to recover the correct profile
of the thin-wall tunnelling solution. This method is applicable to many
nonperturbative problems.

and connections to phase-space and Keldysh field theory formulations [77.34726150561087]
We reformulate the technique of third quantization in a way that explicitly connects all three methods.
We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians.
For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.
