Calculations with 14 quantum bits
(Apr 7, 2011)

Physicists at the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. The experiment brings closer the realization of a quantum computer and gives one of the best demonstrations yet of the quantum mechanical phenomenon of entanglement.

Under the hood with Nintendo's 3D baby
(Mar 25, 2011)

Today sees the UK launch of the Nintendo 3DS, the world's first video game console capable of glasses-free 3D. Will this new display technology add some depth to gaming, or is it just another gimmick? New Scientist has been testing the device to find out.

Prototype quantum computer chip
Quantum computing device hints at powerful future
(Mar 22, 2011)

One of the most complex efforts toward a quantum computer has been shown off at the American Physical Society meeting in Dallas in the US. It uses the strange "quantum states" of matter to perform calculations in a way that, if scaled up, could vastly outperform conventional computers. The 6cm-by-6cm chip holds nine quantum devices, among them four "quantum bits" that do the calculations.
