As we look back on the year at Microsoft Research Redmond, a flood of creative efforts and achievements come to mind. These include mission-focused pursuits aimed at solving urgent challenges, the pursuit of new understandings at the foundations of computer science, and blue-sky initiatives exploring new possibilities. Notable developments, honors, and influences are far too numerous to include in a short blog post, so we can touch on only a small subset of representative milestones.On the foundations front, a stunning set of experiments provided evidence for an elusive particle named the Majorana fermion. A team at the Delft University of Technology, led by Leo Kouwenhoven, used an experimental setup proposed and funded by our Station Q. Majoranas have been proposed as central in enabling an approach to quantum computing being pursued at Station Q.

2012 has been a year of significant developments for the eXtreme Computing Group (XCG), from changes in its organizational structure to project milestones we reached.
One year ago, XCG had several teams with specific technical focus and expertise, in addition to a large but separate engineering group. The intent of such an organizational structure was to have the engineering team not only incubate some of its own project ideas but also to step in and contribute to projects in other parts of XCG. Despite good intentions, such an organizational structure did not serve XCG well. I discovered that it encouraged fragmentation and conflict of interest instead of promoting collaboration. Therefore, we made a few organizational changes. Today, our engineering resources—researchers, developers, program managers—are organized exclusively by their technical expertise, and we no longer have a separate engineering team. XCG has responded well to this change, accomplished early in the year, and we are a more cohesive team than ever before.

Transferring research results into products and services is always a challenging part of Microsoft Research’s job. No two transfers ever happen quite the same way. This year, Microsoft Research Silicon Valley had a tech-transfer experience that is, I believe, unique in the history of Microsoft Research—at least, I can’t remember one of a similar sort in the 11 years I’ve been here.
The technology in this case is a novel form of erasure codes, called “locally reconstructable codes,” that can make a dramatic improvement in the resources required to provide necessary redundancy in a storage-based service. These codes have substantially better space efficiency than classic Reed-Solomon codes, as well as better performance both in normal operation and during error recovery. It is surprising and gratifying that even in a field that has been explored so extensively, it is still possible to make important discoveries.

The inaugural year of Microsoft Research New York City has been stupendous. All of us at Microsoft are thrilled with our newest lab.The lab officially opened on May 3, 2012, with the announcement of a group of 15 founding researchers: David Pennock, Sébastien Lahaie, Justin Rao, David Rothschild, and Giro Cavallo in algorithmic, computational, and empirical economics; Duncan Watts, Dan Goldstein, Sharad Goel, Sid Suri, and Jake Hofman in computational and behavioral social science; John Langford, Miro Dudik, and Alekh Agarwal in machine learning; and Fernando Diaz and Elad Yom-Tov in information retrieval. Together, these researchers bring a deeply original and phenomenally productive approach to data science, particularly in the domains of economics and the social sciences.In the fall, the group was joined by one more member, Jenn Wortman Vaughan, who has done research in machine learning, algorithmic economics, and social science, and who, therefore, was a great match for the lab.

Station Q focuses on the physics of those condensed-matter quantum systems that offer the promise of intrinsic or “topological” protection from error and decoherence. Such systems are likely to play an important role in the architecture of quantum computers. We also enjoy trying to understand what quantum computers will be able to do once they are built.The answer is certainly not in asymptotic formulations; the constants matter. During a recent meeting on quantum chemistry, I learned that for problems that will be at the forefront in the next couple of decades, the limiting factor for quantum algorithms is not the number of qubits but the number of gate operations. One easily produces numbers like 10^20 if one does the “obvious”: imitate the unitary evolution you wish to study with fine “Trotter time steps” and build each step—which, because of the fineness, will agree with the identity matrix to a dozen decimal places—by a composition of millions of gates. Here is a hint that we might think of something cleverer.
