Abstract
A quantum circuit and related manufacturing method are disclosed. The quantum circuit comprises a vertical Josephson junction (1001) formed by a bottom electrode (810) in a first superconducting material layer, a tunnel barrier (830), and a top electrode (820) in a second superconducting material layer. A contact portion (811) and a coupling portion (812) of the bottom electrode are located inside and outside the Josephson junction, respectively. A transmon qubit of the quantum circuit comprises the Josephson junction and a shunt capacitor formed by the top electrode and the contact portion of the bottom electrode as capacitor plates. A readout circuit is capacitively coupled to the bottom electrode through the coupling portion and includes a coupling head (861). The coupling portion is fitted into a recessed portion of the coupling head. The top electrode is configured as a floating electrode, not resistively coupled to the first superconducting material layer.
