A short video explaining what quantum computers are, how they work, and what you’d need to build one.

www.ted.com Stephen Wolfram, creator of Mathematica, talks about his quest to make all knowledge computational — able to be searched, processed and manipulated. His new search engine, Wolfram Alpha, has no lesser goal than to model and explain the physics underlying the universe.TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the “Sixth Sense” wearable tech, and “Lost” producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http Watch a highlight reel of the Top 10 TEDTalks at www.ted.com

default Quantum Computing and the Limits of the Efficiently Computable 2011 Buhl Lecture

Scott Aaronson, an expert in the realm of computational complexity theory and the founder of ComplexityZoo.com online encyclopedia of computational complexity theory delivered Carnegie Mellon University’s 2011 Buhl Lecture. In his lecture titled “Quantum Computing and the Limits of the Efficiently Computable,” Aaronson discusses what quantum computers are, whether they can be built on a large scale, and what’s known today about their capabilities and limitations. He goes beyond quantum computers to touch on speculative models of computation, including closed time-like curves and nonlinearities in the Schrodinger equation — an equation that describes how the quantum state of a physical system changes in time. An associate professor of electrical engineering and computer science at the Massachusetts Institute of Technology, Aaronson’s work on the subject of quantum computing has included limitations of quantum algorithms in the black-box model, the learnability of quantum states, and quantum versus classical proofs and advice. He writes a popular blog (www.scottaaronson.com/blog). For more on the Buhl Lectures, visit: www.cmu.edu

Traditional business applications and platforms are too complicated and expensive. They need a data center, a complex software stack and a team of experts to run them. This short video explains what Cloud Computing is and why it’s faster, lower cost and doesn’t eat up your valuable IT resources.
