Microscopic relaxation channels in materials for superconducting qubits

Microscopic relaxation channels in materials for superconducting qubits

Understanding the connection between qubit coherence and microscopic materials properties is vital for improving device performance. Here, the relaxation times of superconducting transmon qubits are found to be directly correlated with Nb film properties such as grain size and surface oxide composit...
