Honeywell teases “world’s most powerful quantum computer”

Operational technology multinational Honeywell has claimed it has cracked a quantum computing conundrum that will pave the way for the “world’s most powerful quantum computer”.

Honeywell added that it expected to release the record-breaking system within the next three months.

Quantum computers leverage qubits instead of bits to solve problems that ordinary computers would take millions or even billions of years to solve and are roundly expected to accelerate applications such as drug development, weather forecasts and materials design.


Intel breaks subatomic ground with qubit-packed quantum chip

Intel has unveiled a new cryogenic quantum chip that it claims marks a “milestone in the development of a commercially viable quantum computer”.

The chipmaker outlined the technical features of the “Horse Ridge” chip in a research paper released at the 2020 International Solid-State Circuits Conference (ISSCC) in San Francisco. 


Delta, Goldman Sachs latest additions to IBM quantum computing network

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.


I like to qubit, qubit – AWS debuts quantum computing service

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 officially claims quantum supremacy, ignores IBM criticism

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.
