Kay Malmstrom Lecture in Physics
Building a Quantum Computer
The 2023 Malmstrom Lecture was held on October 26 with guest lecturer John Martinis PhD, professor of physics at University of California, Santa Barbara.
Nature allows the storage and manipulation of data in new and powerful ways using quantum mechanics.
In his lecture, Martinis will explain the basic concepts behind the exponential power of this technology and how to build a quantum computer using superconductors. Additionally, he will show experimental data on a “quantum supremacy” experiment with 53 qubits using the Sycamore processor.
The Sycamore processor takes about 200 seconds to run a quantum circuit a million times—the equivalent task for a state-of-the-art classical supercomputer would take thousands of years.
Finally, Martinis will explain some of the future uses of quantum algorithms and what may be in store for the field in the next 10 years.
John Martinis PhD, professor of physics at University of California, Santa Barbara
John Martinis pioneered experiments in superconducting qubits in the mid 1980s for his PhD thesis. During his career, Martinis has worked on a variety of low temperature device physics, and now primarily focuses on quantum computation since the late 1990s. In 2014, he was awarded the Fritz London Memorial Prize in Low Temperature Physics for his work.
From 2014 to 2020, Martinis worked at Google to build a useful quantum computer, culminating in a quantum supremacy experiment in 2019. Then, in 2021, he was awarded the John Stewart Bell Prize.
About the Malmstrom Lectures in Physics
The Kay Malmstrom Lecture in Physics, part of the Emma K. and Carl R. N. Malstrom Chair in Physics, is an annual symposium on contemporary issues and research in physics. Through this generous gift, Carl R. N. Malmstrom ’36 gives Hamline students access to the outstanding scientific minds of our time. Even after his death in 2010, Carl’s legacy of supporting Hamline students continues to fund collaborative research opportunities, scholarships, and this lecture.
