- Abstract summary: We discuss the implementation of quantum algorithms for lattice $Phi4$ theory on circuit quantum electrodynamics (cQED) system.
The main advantage of qudit systems is that its multi-level characteristic allows the field interaction to be implemented only with diagonal single-qudit gates.

- Abstract: We discuss the implementation of quantum algorithms for lattice $\Phi^4$
theory on circuit quantum electrodynamics (cQED) system. The field is
represented on qudits in a discretized field amplitude basis. The main
advantage of qudit systems is that its multi-level characteristic allows the
field interaction to be implemented only with diagonal single-qudit gates.
Considering the set of universal gates formed by the single-qudit phase gate
and the displacement gate, we address initial state preparation and
single-qudit gate synthesis with variational methods.

We present an algorithm for simulating universal quantum circuits composed of "free" nearest-neighbour matchgates or equivalently fermionic-linear-optical (FLO) gates, and "resourceful" non-Gaussian gates.
Our key contribution is the development of a novel phase-sensitive algorithm for simulating FLO circuits.
For a quantum circuit containing arbitrary FLO unitaries and $k$ controlled-Z gates, we obtain an exponential improvement $k$O(4.5k)$O over the prior state-of-the-art.
