About 100 billion optical components would be needed to create a practical quantum computer that uses light to process information. That is the conclusion of physicists in the UK, who have calculated how many components are required to make a fault-tolerant linear optical computer. Their comprehensive study found that the total number of required components for a photon-based computer would be at least five orders of magnitude larger than for a matter-based processor.
So, you can forget about that quantum laptop. To read more, click here.
