Error-corrected quantum computing demands the seamless integration of tens of thousands of qubits. However, the scaling of superconducting qubits, the leading quantum computing platform in the near-term, is limited by the size of the comprising microwave components and cryostats that house them. As a result, extensive materials research is needed to engineer platforms that are ideal for fault-tolerant and scalable quantum hardware.
In this webinar, we will provide an overview of the state-of-the-art for solid-state quantum hardware and the requirements to transition the field into the regime of “quantum advantage,” in which quantum computers demonstrably solve certain real-world problems faster than classical computers. We will then discuss multiple strategies to break through the existing scaling bottlenecks, including 1) voltage-tunable quantum devices, and 2) distributed scaling via optical-microwave transduction. The common denominator for all the strategies is the development of low-loss hybrid normal–superconductor materials systems, ranging from superconductor–semiconductor to superconductor–piezoelectric oxides.
Overall, we will emphasize the significant role materials research plays in the development of emerging quantum technologies.
