An international group of scientists led by researchers from the University of California in Santa Barbar have taken the first steps toward creating a quantum computer — in a diamond. So far they’ve built a two-qubit unit for a quantum computer. A qubit is the quantum computing equivalent of a bit, and it can be both on and off at the same time, unlike a regular bit which must be in one state or the other. The electron spin precesses extremely fast in a magnetic field, while the nuclear spin is about 1,000 times slower.
