Title:

Scaling up quantum processors with superconducting qubits

Abstract:

Superconducting qubit systems have become a promising platform for quantum computing due to significant material and design advances over the past two decades. To move the field closer towards practical quantum computing applications, there has been a strong focus on increasing the qubit count of quantum processors while maintaining high-fidelity gate operations.  In this talk, I will give examples of current challenges with developing superconducting qubit devices before presenting on the elements involved in making a high-performing and scalable superconducting qubit device. In particular, I will focus on one of the techniques used to achieve high-fidelity gates on smaller-scale multi-qubit devices, which entails adjusting the coupling strength between qubits. I will then show how we can scale up these devices by presenting some of our recent prototypes of modular superconducting qubit processors.
