Abstract: Error-corrected quantum computing demands seamless integration of 10s of thousands of qubits. While superconducting qubits take the leading role in near-term quantum computing, their scaling is limited by the size of the comprising microwave components and cryostats that house them. This beckons extensive materials research to engineer platforms ideal for fault-tolerant and scalable quantum hardware. Here, I will provide an overview of the state-of-the-art for solid-state quantum hardware and the requirements to transition the field into the “Quantum Advantage” regime. I will then discuss three different strategies to break through the existing scaling bottlenecks including 1) voltage-tunable quantum devices; 2) distributed scaling via optical-microwave transduction; 3) topologically protected quantum processors. I will outline the common denominator for all three strategies, which is the need to realize low-loss hybrid normal-superconductor materials systems ranging from superconductor-semiconductor to superconductor-piezoelectric oxides. With this approach, I hope to emphasize the significant role materials research plays in the development of emerging quantum technologies.
Biography: Kasra Sardashti is an Assistant Professor of Physics & ECE at Clemson University. His research group, the Laboratory for Band Engineering of Quantum Systems (LaBEQs) works on a number of projects focused on integrating hybrid systems into functional devices for quantum information processing, sensing, and communication. He is the lead PI of an NSF Quantum Interconnect Challenge Program (NSF-QuIC) working on developing the first generation of quantum random access memories. He is also the recipient of the Powe Junior Faculty Enhancement Award offered annually by the Oak Ridge Associated Universities. Before joining Clemson, he served as a Research Scientist at NYU Center for Quantum Phenomena. He received his Ph.D. in Materials Science and Engineering from UC San Diego in 2016. Kasra is the author and co-author of over 40 journal and conference papers. His work has been featured in various journals and conferences including Applied Physics Letters, Advanced Energy Materials, Nature Communications, Nano Letters, and Phys Rev Materials.
