Multi-mode Cavity Centric Architectures for Quantum Simulation

Quantum Simulation is an algorithm of interest, however current devices are yet to surpass classical techniques. For problems of interest, large degrees of entanglement are required. Another challenge is that qubits sit idle whilst alternating terms are implemented. 2D planar superconducting are hindered by their nearest neighbor topology and short lifespan. One technology of interest is the multi-mode superconducting resonator. We observe that these cavities have a natural topology that aligns well with quantum simulation, and exhibit longer lifespans in comparison to other superconducting hardware. We discuss the integration of these devices and their implications to quantum simulation. We report the development of a transpiler for quantum simulation, leading to reductions of up to 82% in circuit depths. Additionally, our investigation demonstrates improvements of up to 19.4% in results from Variational Quantum Algorithms.
