Developing Building Blocks of Superconducting Quantum Processors in a Flip-Chip Architecture
ORAL
Abstract
We will present our recent results on demonstrating single-qubit and two-qubit flip-chip integrated devices with performances close to the state-of-the-art flip-chip devices. Our approach employs the two-chip stack, thereby allowing the separation of processor's components into different planes. This enables design of input/output circuitry routing schemes that are scalable to hundreds of qubits. Notably, at this level of performance, the qubit coherence has not been substantially affected by the presence of another chip in proximity. We will end the talk by showing our progress towards implementing multi-qubit processors beyond two-qubit devices.
