Low-temperature transport measurements were performed on a two-terminal Aharonov–Bohm interferometer with one Coulomb-blockaded quantum dot (QD) embedded in each of the two interfering paths. Layered local anodic oxidation of the Ga[Al]As heterostructure and a thin titanium top gate give full tunability of the inter-dot tunnel coupling from purely capacitive to the QD molecule regime and of the ...
