Recent research progress  has renewed enthusiasm for finding avenues to build significantly more powerful quantum computers.

• IBM has begun a five-year research project based on advances made in the past year at Yale University and the University of California, Santa Barbara that suggest the possibility of quantum computing based on standard microelectronics manufacturing technologies.
• Researchers at Toshiba Research Europe and Cambridge University reported in Nature that they had fabricated light-emitting diodes coupled with a custom-formed quantum dot, which functioned as a light source for entangled photons.
• Google has received a proposal from D-Wave and NASA’s Jet Propulsion Laboratory to develop a quantum computing facility for Google next year based on D-Wave technology.
