Caltech and Amazon Partner to Create New Hub of Quantum Computing

10-26-21

This past year, a new two-story building took shape in the northeast corner of the Caltech campus. Though modest in design, what takes place inside the structure could transform the future of computing. The building is the AWS Center for Quantum Computing, the result of a partnership between Caltech and Amazon Web Services, the cloud-computing branch of Amazon. The goal of the collaboration is to create quantum computers and related technologies that have the potential to revolutionize data security, machine learning, medicine development, sustainability practices, and more. "AWS will benefit from the ideas percolating here on campus," says Oskar Painter, John G. Braun Professor of Applied Physics and Physics and head of quantum hardware at AWS. Painter says quantum computing is still a very young technology, so it is crucial for development efforts to be directly connected to the latest research in academia. [Caltech story]

Paul Rothemund Places Molecule-Scale Devices in Precise Orientation

02-22-21

Paul Rothemund, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems, has developed a technique that allows him to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation. This method for precisely placing and orienting DNA-based molecular devices may make it possible to use these molecular devices to power new kinds of chips that integrate molecular biosensors with optics and electronics for applications such as DNA sequencing or measuring the concentrations of thousands of proteins at once.

Advancing Future Quantum Science Efforts

08-27-20

Five new Department of Energy centers will apply quantum information science to emerging technologies. The centers will develop cutting-edge quantum technologies for use in a wide range of possible applications including scientific computing; fundamental physics and chemistry research; and the design of solar cells and of new materials and pharmaceuticals. Caltech faculty will participate in four of the new science centers: the Quantum Systems Accelerator, led by the Lawrence Berkeley National Laboratory, also known as Berkeley Lab; the Quantum Science Center, led by Oak Ridge National Laboratory; Q-NEXT, led by Argonne National Laboratory; and the Co-design Center for Quantum Advantage, led by Brookhaven National Laboratory.

Professor Vahala Elected to the National Academy of Engineering

02-06-20

Kerry J. Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics; Executive Officer for Applied Physics and Materials Science, has been elected to the National Academy of Engineering (NAE). Professor Vahala was elected for “research and application of nonlinear optical microresonators to the miniaturization of precision time and frequency systems." Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature," and to "the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

Researchers Develop New Quantum Algorithm

12-19-19

Austin Minnich, Professor of Mechanical Engineering and Applied Physics, Fernando Brandão, Bren Professor of Theoretical Physics, and Garnet Chan, Bren Professor of Chemistry, have developed an algorithm for quantum computers that will help them find use in simulations in the physical sciences. The new algorithm allows a user to find the lowest energy of a given molecule or material. Many people are interested in how to simulate the ground states of molecules and materials. "If we want to do a simulation of water, we could look at how water behaves after it has been blasted into a plasma—an electrically charged gas—but that's not the state water is usually found in; it is not the ground state of water. Ground states are of special interest in understanding the world under ordinary conditions," says Chan. [Caltech story]

Professor Wierman Finishes First in Class in LA Triathlon

04-14-14

On Sunday April 13, 2014, Adam Wierman, Professor of Computer Science, and his Rigorous Systems Research Group (RSRG) members joined the approximate 700 people competing in the Los Angeles Triathlon Series at Bonelli Par. Professor Wierman finished 1st in his race class and 13th overall among individuals competing in the Tri-Express, which consisted of a 300-meter swim in Puddingstone Lake, a 13.91-kilometer bike course, and a 5-kilometer run through the Park.
