pivot lets build a transmon dont run it just build it = transmon superconducting qubit Josephson junction shunted by large capacitor dont run just build

TRANSMON BUILD DONT RUN IT JUST BUILD IT

EJ/EC ratio charge insensitive EJ/EC >> 1 transmon regime

80 = EJ/EC = 80 transmon regime EJ/EC >> 1 charge insensitive EJ=Josephson energy EC=charging energy

Capacitor size shunting capacitor large C reduces EC

70 = capacitor size large shunting capacitor C reduces charging energy EC = e^2/2C

Resonator coupling g readout resonator coupling

50 = coupling g readout resonator coupling dispersive readout
