a,b, (1) CZ decompositions of the distributed iSWAP (a) and SWAP (b) circuits, comprising two and three instances of QGT, respectively. (2) The reconstructed process matrices for the iSWAP (a) and SWAP (b) gates indicate average gate fidelities of 70(2)% and 64(2)%, respectively. c, Grover’s algorithm. (1) Circuit comprising two instances of QGT: the first implements the Grover oracle call, which marks a particular state, a, and the second implements the diffusion circuit. (2) Measurement outcomes from 500 repetitions of Grover’s algorithm per marked state; the average success probability is 71(1)%. All error bars indicate one standard deviation.
