  Near-term quantum computing technologies grapple with huge complexity
overheads, hindering their ability to induce algorithms, necessitating
engineering and scientific innovations. One class of problems of interest is
Quantum Simulation, whereby quantum systems are simulated using a quantum
computer. However, current devices are yet to surpass classical tensor network
techniques. For problems of interest, where classical simulation techniques
fail, large degrees of entanglement are required. Another challenge of
implementing quantum simulation problems is that qubits sit idle whilst
alternating simulation terms are implemented, exposing the system to
decoherence. In the near term, 2D planar superconducting lattices of
circuit-QED elements such as the transmon continue to draw substantial
attention, but they are hindered by their nearest neighbor topology and
relatively short lifespan, two problems that are problematic for quantum
simulation. One technology of particular interest is the multi-mode
superconducting resonator capable of storing multiple qubits in one device. We
observe that these cavities have a natural virtual topology that aligns
particularly well with quantum simulation problems, and exhibit much longer
lifespans in comparison to other planar superconducting hardware. In this paper
we present MUCIC, we discuss the simple integration of these devices into the
current landscape and their implications to quantum simulation, motivated by
their alignment to the quantum simulation problem, and potential as a quantum
memory candidate. We report the development of MUCICs transpiler, leading to
reductions of up to 82% in quantum simulation circuit depths. Additionally, our
investigation demonstrates improvements of up to 19.4% in converged results
from Variational Quantum Algorithms.
