“…Motivated by the quest for quantum error correction and expanding the set of realisable circuits, 1,2 there has been a great effort to improve the design of entangling gates, [1][2][3][4][5][6][7][8][9][10][11] and by now there is a rich array of design choices in a variety of quantum computing modalities, including superconducting quantum circuits, 12 trapped ions, 13 quantum dots 14 and NV diamonds. 15,16 Notable designs for entangling gates in superconducting circuits, include fast adiabatic gates, 17 frequency modulation, 11,18 cross resonance 19,20 and resonator-induced phase, 21,22 which effect the gates using longitudinal (first two) or transverse (last two) control of the qubits.…”
