January 02, 2019Practical quantum computers may be another step closer to reality, thanks again to graphene. The bits of information in quantum computers (qubits) can exist in two states at once, and now researchers have managed to record just how long that superposition state can last in a qubit made of graphene.

May 18, 2017Having provided access to a quantum processor through the cloud for a year, IBM is revealing a new generation of processors. A 16-qubit processor will increase the processing power available through the cloud, while the second is twice as powerful again and designed for commercial applications.

May 09, 2017The next big breakthrough for electronics is likely to be quantum computers, but there are still plenty of hurdles to jump before they become a reality. A team from Aalto University in Finland may have cleared one of those obstacles, developing a “nanorefrigerator” to help cool components down.
