Abstract: Interconnections for connecting flex circuit boards in classical and/or quantum computing systems can include a first flex circuit board having a removed portion that exposes one or more signal lines and a second flex circuit board having a removed portion that exposes one or more other signal lines. The flex circuit boards can be aligned at the removed portions to form a signal trace gap near the exposed signal lines. Exposed signal lines of the first flex circuit board can be coupled with exposed signal lines of the second flex circuit board. A ground support layer can be coupled to the first flex circuit board and the second flex circuit board along the same side. An isolation plate at least partially covering the signal trace gap can be coupled to the first flex circuit board and/or the second flex circuit board on a side opposite of the ground support layer.

Abstract: An interconnection for flex circuit boards used, for instance, in a quantum computing system are provided. In one example, the interconnection can include a first flex circuit board having a first side and a second side opposite the first side. The interconnection can include a second flex circuit board having a third side and a fourth side opposite the third side. The first flex circuit board and the second flex circuit board are physically coupled together in an overlap joint in which a portion of the second side for the first flex circuit board overlaps a portion of the third side of the flex circuit board. The interconnection can include a signal pad structure positioned in the overlap joint that electrically couples a first via in the first flex circuit board and a second via in the second flex circuit board.

Abstract: A laminated circuit assembly for filtering signals in one or more signal lines in, for instance, a quantum computing system is provided. In one example, the laminated circuit assembly includes one or more signal lines disposed within a substrate in a first direction. The laminated circuit assembly includes a dielectric portion of the substrate. The laminated circuit assembly includes a filter portion of the substrate extending in a first direction and containing a frequency absorbent material providing less attenuation to a first signal of a first frequency than to a second signal of a second, higher frequency. The filter portion is configured to attenuate infrared signals passing through the one or more signal lines.
