Here we present the succesful integration of Fermilab high Q cavities with Rigetti superconducting qubits, including the coherence times of the resulting 3D SRF qubits and various quantum state manipulations demonstrating the key advantages of the long coherence. We also present further improvements in the coherence of 3D SRF qubits via targeted surface studies and treatments, and discuss the emerging near-term prospects for the 3D SRF qubit-based QPUs capabilities.
