Superconducting interposer for the transmission of quantum information for quantum error correction

A quantum system, comprising:

• an ancilla qubit chip disposed in a containment vessel, the ancilla qubit chip comprising a plurality of ancilla qubits;
• a data qubit chip disposed in the containment vessel and spaced apart from said ancilla qubit chip, said data qubit chip comprising a plurality of data qubits;
• and
• an interposer coupled to said ancilla qubit chip and said data qubit chip and disposed in the containment vessel, said interposer comprising a dielectric material and a plurality of superconducting structures formed in said dielectric material,
• wherein a data qubit of said plurality of data qubits has a first frequency, an ancilla qubit of said plurality of ancilla qubits has a second frequency, and a superconducting resonator comprising a superconducting structure of said plurality of superconducting structures formed in said interposer has a third frequency,
