Latest quantum computing publications
IBM is on track to lead the quantum computing revolution with the news that over 100 organisations have signed up to the company’s initiative to advanced practical uses of the technology.
The latest members to the program, which gives participants access to quantum experts, developer tools and cloud-based quantum systems via IBM Q Cloud, include Delta Airlines, Wells Fargo and Stamford University.
Amazon has finally made its entrance into the quantum arena with the launch of a service for AWS that enables scientists and developers to experiment with the weird and wonderful world of quantum computing.
Braket, named after the common notation for quantum states, launched in preview today and will compete with IBM, Microsoft and Google on the futuristic frontier of cloud-based quantum computing. IBM launched its quantum cloud service in 2016, while Google and Microsoft plan to launch similar services in the near future.
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.
