f , The experimental results of SWAP oscillations, showing measured singlet probabilities P S as a function of operation time t wait and the detuning voltage i j for Q1Q2 ( d ), Q2Q3 ( e ) and Q3Q4 ( f ). The initial states of two qubits (before the SWAP oscillations) are denoted on the top, and the qubit pair that is read out is indicated by the dashed arrow showing the readout pulse direction.
