Latest quantum computing publications
Google recently sent the internet in a frenzy after the company claimed in a leaked research paper to have achieved “quantum supremacy”. At the time the quantum community fiercely debated Google’s claim.
While the draft paper was swiftly pulled offline, Google has doubled down by officially releasing a peer-reviewed version in Nature which reiterates its achievement. Crucially, the article repeats the controversial claim that the problem its Sycamore processor solved would take Summit, the world’s most powerful supercomputer, 10,000 years to complete.
If true, this would effectively mean Google had satisfied John Preskill’s original definition of quantum supremacy, described as the milestone where quantum computers can perform tasks that classical computers cannot.
A new pilot project that aims to build the most secure communications infrastructure in Europe has been unveiled, bringing together 38 partners from industry and academia including four UK organisations.
Toshiba Research Europe (TREL), BT, the National Physical Laboratory and the University of Cambridge said they will join the OPENQKD initiative that aims to boost the security of critical applications in telecoms, healthcare, electrical supply and government services.
In July, researchers from the University of Glasgow mesmerised the world with a breathtaking image of a form of quantum entanglement known as Bell entanglement, capturing the phenomenon on camera for the first time.
