Scientists are developing a quantum computing technology that could be used to outpace conventional supercomputers by so much they could become a thing of the past.
A team at the University of Rochester in the US are developing a processor which they claim combines elements of quantum mechanics and laser technology, capable of processing a large batch of computations simultaneously.
Using today's electron powered computing, processors must do computations in sequence. But using a laser to power the processes can increase the speed of the processor a thousand-fold.
Based on a hugely complex concept called 'quantum interference', the scientists have been able to bypass some of the more unpredictable and arcane elements of 'quantum entanglements' by using laser beams, which are much easier to control.
Essentially, what the team has done is build a computer that mimics the ability of a difficult to control 'quantum interference' machine by building a 'light interference' machine, based on laser technology.
The team likened the quantum processor to a multitude of librarians all scanning the same library for a book at once, whereas normal processors can only provide the one librarian to scan the entire library.
