Quantum Instruction Set: The Good, the Bad, and the Future

讲演择要：
Over the past two decades, we have witnessed rapid progress in quantum hardware. However, the interface that quantum hardware should offer has rarely been discussed. In this talk, I will explain how the choice of native gate set, or quantum instruction set from a computer science perspective, can dramatically impact the performance of quantum hardware.

More specifically, I will showcase several quantum instruction set designs that can improve accuracy by hundreds to even millions of times in quantum program execution, or significantly mitigate the overhead caused by limited connectivity, on the current generation of superconducting quantum processors. I will also discuss the necessary experimental toolchains required to control, calibrate, and characterize new quantum instruction set designs.
Finally, I will conclude with an outlook on the interface that future quantum hardware should offer.

讲演人简介：
Jianxin Chen is currently a visiting scholar at Tsinghua University and will join its Computer Science Department as a tenured faculty member later this year. He earned both his Bachelor’s and Ph.D. degrees in Computer Science from Tsinghua University. Following his doctoral studies, he pursued postdoctoral research at the University of Waterloo and the University of Maryland. He then led the systems team, as well as the North America team, at Alibaba Quantum Laboratory.
Jianxin’s primary research focus is on the development of robust and fault-tolerant quantum computer systems.
