Abstract: Embodiments of the present disclosure provide improved layout designs for quantum circuit assemblies employing qubits, e.g. superconducting qubits. One proposed design involves increasing a capacitance between a first qubit and a coupling component that couples the first qubit to a second qubit. Another design involves rounding of one or more corners at the end portions of coupling components. Yet another design involves varying the distance between two electrically conductive elements of a given superconducting qubit device which are connected to one another via one or more non-linear inductive elements. Qubit layout designs described herein may help increase coupling strength between qubits, allow greater design flexibility in achieving faster multi-qubit gates, and/or reduce or mitigate the negative effects of two-level systems.
