Figure 3: Pulse sequences.
From: Measurement of geometric dephasing using a superconducting qubit
Pulse sequences for protocol R (where the direction of precession of the magnetic field is reversed in the second half of the spin echo) and protocol P (where it is preserved). The π- and π/2-pulses implementing the spin echo are on resonance with the qubit transition frequency ω01 (purple). At the end of the sequence, the state of the qubit is read out by applying a tone at frequency ωr (orange). The components Ωx and Ωy of the magnetic field are shown in dark and light blue. Δ is kept constant and is not shown.
