Quantum Computing
Although still in their infancy, quantum computers are set to deliver an incredible leap forward in computing capabilities.

Practical 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.

The 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.

Current quantum processors were once thought of as only precursors to creating future quantum computers, and too simple to do anything useful on their own. Now researchers have discovered a way to use them to solve very specific tasks much faster than normal computers can today
-
Through IBM Quantum Experience, the public will be able to experiment with individual quantum bits (qubits), process their own experiments, and run some of their own algorithms directly on IBM's quantum processor.
-
Scientists have successfully trialled a quantum "data bus" – a system that transfers quantum information from one place to another, which had previously only been theorized. They accomplished this feat with a technique called perfect state transfer.
