10-qubit register breaks new ground in quantum computing

Imperfections in diamond enable a 10-qubit register – a collection of qubits that can store data in a quantum computer – report researchers at Delft University of Technology in the Netherlands and Element Six in the UK. Their diamond-based system is capable of preserving an arbitrary single-qubit state for over a minute – a record for a solid-state qubit. The multiqubit register signifies important progress in quantum-information processing, which requires a large number of qubits.
