We have embedded two fixed-frequency ${\mathrm{Al}/\mathrm{AlO}}_{x}$/Al transmons, with ground-to-excited transition frequencies at 6.0714 and 6.7543 GHz, in a single three-dimensional Al cavity with a fundamental mode at 7.7463 GHz. Strong coupling between the cavity and each transmon results in a...
