When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison.

But, before that happens, quantum physicists like the ones in UC Santa Barbara’s physics professor John Martinis’ lab will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit (“qubit”), while compensating for its high vulnerability to environmentally-induced error.

Light: It’s all around us and is an integral part of our daily lives. Yet it continues to surprise us with its distinctive properties, such as how its various wavelengths can be utilized for imaging things invisible to the naked eye, or how it can store and transmit massive amounts of data, or how it can generate energy.

Like the shape-shifting robots of “Transformers” fame, a unique class of proteins in the human body also has the ability to alter their configuration. These so-named intrinsically disordered proteins (IDPs) lack a fixed or ordered three-dimensional structure, which can be influenced by exposure to various chemicals and cellular modifications.

A team of chemistry and materials science experts from University of California, Santa Barbara and The Dow Chemical Company has created a novel way to overcome one of the major hurdles preventing the widespread use of controlled radical polymerization.

Three UC Santa Barbara researchers — a computer scientist, a chemical engineer and a physicist — are among the recent recipients of the National Science Foundation’s Faculty Early Career Development (CAREER) award. The NSF CAREER Program offers the NSF’s most prestigious awards to young faculty who most effectively integrate research and education.

Dancing around a marshmallow tower they built themselves, the children shouted: “Ten and a quarter! Ten and a quarter!” They marveled that their group’s tower was the tallest, but some of their sheer joy may have been fueled by the marshmallows themselves.

The group constructed the tower as part of UCSB Summer Science Camp, where 8- to 12-year-olds come to get down and dirty in the name of science. Whether learning about bacteria, DNA and density or building gumdrop domes and dissecting squid, participants are having the time of their lives.

Modern computers are not unlike the looms of the industrial revolution: They follow programmed instructions to weave intricate patterns. With a loom, you see the result in a cloth or carpet. With a computer, you see it on an electronic display.

Now a group of physicists and computer scientists funded by Microsoft is trying to take the analogy of interwoven threads to what some believe will be the next great leap in computing, so-called quantum computing.

Physicists at UC Santa Barbara have created a microscopic device to assist biologists in making very fast molecular measurements that aid the understanding of protein folding. This development may help elucidate biological processes associated with diseases such as Alzheimer’s and Parkinson’s. Since proteins in the body perform different functions according to their shape, the folding process is considered a key area of study.
