Science News reports on advances in using diamond in quantum computing, A diamond based device employing a nitrogen nucleus’ spin as one qubit, and an electron’s spin as the other. When the system was used to solve a problem using an unsorted database and succeeded on the first try 95% of the time, when a non-quantum computer should only be successful half the time, it indicated that a quantum effect was taking place.

Other advances announced this week include hacker resistant encryptionand more reliable method of moving qubit encoded electrons.
