DailyDirt: Quantum Computers Are Both Here And Not Here...

- Lockheed Martin bought a D-Wave Systems quantum computer in 2011, and there are a few other customers and partners trying to develop for this particular computer. NASA, Google, and Aerospace Concepts are testing out these new-fangled machines to solve optimization problems and machine learning, among other things quantum information can tackle. [url]
- The availability of ultra-pure silicon could make it a bit easier to build quantum computers, and now a straightforward process for obtaining 99.9999% pure silicon is practical. Pure silicon is a good substrate for holding a qubit, as substrate impurities negatively affect the performance of quantum manipulations. [url]
- Google has played around with D-Wave quantum computers to study computer vision problems with a few qubits. In 2007, D-Wave had a 16-qubit system, and now it has a 512-qubit computer. It's improving with time, but it's not entirely clear when this system is better than a traditional x86 processor. [url]
