High-coherence superconducting qubits made using industry-standard, advanced semiconductor manufacturing

Understand

The development of superconducting qubit technology has shown great potential for the construction of practical quantum computers.

• As the complexity of quantum processors continues to grow, the need for stringent fabrication tolerances becomes increasingly critical.
• Utilizing advanced industrial fabrication processes could facilitate the necessary level of fabrication control to support the continued scaling of quantum processors.
• However, these industrial processes are currently not optimized to produce high coherence devices, nor are they a priori compatible with the commonly used approaches to make superconducting qubits.
