Abstract
A system for quantum error correction can store quantum information while supporting controlled interactions for syndrome measurements. The system includes a plurality of fluxonium qubits arranged as data qubits. The system further includes a plurality of transmon qubits arranged as ancilla qubits, each positioned between a respective first fluxonium qubit and a respective second fluxonium qubit. The system further includes, for each transmon qubit, a tunable coupling element connected between the first and second fluxonium qubits. The system further includes a coupling control circuit connected to each tunable coupling element, the coupling control circuit configured to set a desired coupling strength during active operations and to increase the impedance state during idle periods to isolate the fluxonium qubits from residual interactions, thereby improving coherence times and reducing error rates in quantum computation.
