This TSF phenomena could come from a charge offset fluctuation in the superconducting islands in the circuit. The value of the split could be predicted form the circuit parameters. Understanding the mechanism of the fluctuation and its dynamics is important to make noise-resilient superconducting qubits for practical quantum computers.
