We study the charge noise SQ in Josephson qubits produced by fluctuating two-level systems TLSs with electric-dipole moments in the substrate. The TLSs are driven by an alternating electric field of angular frequency and electric field intensity I. It is not widely appreciated that TLS in small qubits can easily be strongly saturated if I Ic, where Ic is… CONTINUE READING
