Claim 14:
15. A method for producing a wiring structure for a quantum computing system, comprising:
obtaining a first flex circuit board comprising a first ground plane, a first dielectric layer, a first set of one or more signal lines, a second dielectric layer, and a second ground plane;
obtaining a second flex circuit board comprising a third ground plane, a third dielectric layer, a second set of one or more signal lines, a fourth dielectric layer, and a fourth ground plane;
removing a portion of the first flex circuit board, thereby creating a removed portion of the first flex circuit board exposing at least one signal line in the first set of signal lines;
removing a portion of the second flex circuit board, thereby creating a removed portion of the second flex circuit board exposing at least one signal line in the second set of signal lines;

aligning the removed portion of the first flex circuit board and the removed portion of the second flex circuit board, thereby forming a signal trace gap having a first surface;
coupling the at least one signal line in the first set of one or more signal lines and the at least one signal line in the second set of one or more signal lines at the signal trace gap via a solder bridge; and
coupling an isolation plate to the wiring structure such that the isolation plate at least partially covers the signal trace gap and the solder bridge is disposed between the isolation plate and the first surface of the signal trace gap.
