Abstract: A quantum bit (qubit) flip chip assembly is formed when a qubit is formed on a first chip and an optically transmissive path is formed on a second chip. The two chips are bonded using solder bumps. The optically transmissive path provides optical access to the qubit on the first chip.

Abstract: Embodiments of the present invention disclose a computer system having a plurality of quantum circuits arranged in a two-dimensional plane-like structure, the quantum circuits comprising qubits and busses (i.e., qubit-qubit interconnects), and a method of formation therefor. A quantum computer system comprises a plurality of quantum circuits arranged in a two-dimensional pattern. At least one interior quantum circuit, not along the perimeter of the two-dimensional plane of the plurality of quantum circuits, contains a bottom chip, a device layer, a top chip, and a routing layer. A signal wire connects the device layer to the routing layer, wherein the signal wire breaks the two dimensional plane, for example, the signal wire extends into a different plane.
