PRINTED CIRCUIT BOARD TO DIELECTRIC LAYER TRANSITION WITH CONTROLLED IMPEDANCE AND REDUCED AND/OR MITIGATED CROSSTALK FOR QUANTUM APPLICATIONS

摘要

A transition between a printed circuit board and a dielectric layer with controlled impedance and reduced and/or mitigate crosstalk for quantum applications are provided. A quantum device can comprise a microwave quantum circuit on a dielectric substrate and a printed circuit board comprising a via that comprises a transmission line. A wirebond between the transmission line of the printed circuit board and a transmission line of the microwave quantum circuit operatively couples the microwave quantum circuit to the printed circuit board. The via comprises a defined characteristic impedance. The wirebond provides a microwave signal connection between the printed circuit board and the microwave quantum circuit.
