Detecting the transmission phase of a quantum dot via interferometry canreveal the symmetry of the orbitals and details of electron transport.Crucially, interferometry will enable the read-out of topological qubits basedon one-dimensional nanowires. However, measuring the transmission phase of aquantum dot in a nanowire has not yet been established. Here, we exploit recentbreakthroughs in the growth of one-dimensional networks and demonstrateinterferometric read-out in a nanowire-based architecture. In our two-pathinterferometer, we define a quantum dot in one branch and use the other path asa reference arm. We observe Fano resonances stemming from the interferencebetween electrons that travel through the reference arm and undergo resonanttunnelling in the quantum dot. Between consecutive Fano peaks, the transmissionphase exhibits phase lapses that are affected by the presence of multipletrajectories in the interferometer. These results provide critical insights forthe design of future topological qubits.
