Stabilizer-based Hamiltonian Engineering using Superconducting Qubits
Abstract
We propose to investigate the benefits of using strong interactions between individual qubits to realize coupled devices that are protected from error-inducing noise. Our plan is to strongly couple multiple nearly-degenerate superconducting qubits such that errors in the individual qubits become energetically unfavorable. We will develop strong coupling elements using superinductances and Josephson junctions. The fluxonium qubit will be our testbed qubit, which will allow us to leverage recent developments in improving the coherence and control of the fluxonium and coupling between fluxonium qubits to achieve our goal. A key technological development of our project will be readout and control methods for arrays of superconducting qubits. If successful, our project will improve the gate fidelities of currently-available superconducting qubits and will serve as a stepping stone between currently-available qubits and active quantum error correction. In addition to making better qubits, our technological developments would also expand the range of Hamiltonians that could be simulated by the superconducting qubit community.
