Chipmaker Intel has become the latest big tech company to enter the quantum race with a 12-qubit silicon-based quantum processing unit (QPU). The chip has been named Tunnel Falls and will initially only be available to researchers for experimentation.

Few specific details have been revealed about the actual QPU. It is a silicon spin chip that is machined using Intel’s existing transistor industrial fabrication capabilities. This, says the company, will allow it to scale more quickly as the hardware advances, as it could potentially be produced utilising existing production lines.
