A team of scientists of the Kavli Institute of Nanoscience of TU Delft and the FOM Foundation has succeeded in very accurately initializing and reading out a mini-quantum computer comprising four quantum bits on a chip of diamond. This breakthrough marks an important step towards a quantum computer and makes it possible to test advanced quantum protocols, such as teleportation, on a chip. The researchers have published their results in Nature 477, 574 (2011).
