Google scientists say they’ve achieved ‘quantum supremacy’ breakthrough over classical computers
Posted by Shane Hinshaw in categories: computing, quantum physics
The achievement has been compared to the Wright brothers’ 12-second first flight at Kitty Hawk — an early, aspirational glimpse at a revolution to come. By providing exponentially greater calculation power than the machines we use today, quantum computers could one day transform the way we communicate ideas, conceal data and comprehend the universe.

Quantum leap in computing as scientists claim ‘supremacy’
Posted by Tracy R. Atkins in categories: computing, quantum physics
Paris (AFP) — Scientists claimed Wednesday to have achieved a near-mythical state of computing in which a new generation of machine vastly outperforms the world’s fastest super-computer, known as “quantum supremacy”.
A team of experts working on Google’s Sycamore machine said their quantum system had executed a calculation in 200 seconds that would have taken a classic computer 10,000 years to complete.
A rival team at IBM has already expressed scepticism about their claim.

Air-breathing engine precooler achieves record-breaking Mach 5 performance
Posted by Klaus Baldauf in categories: engineering, space
UK company Reaction Engines has tested its innovative precooler at airflow temperature conditions equivalent to Mach 5, or five times the speed of sound. This achievement marks a significant milestone in its ESA-supported development of the air-breathing SABRE engine, paving the way for a revolution in space access and hypersonic flight.
The precooler heat exchanger is an essential SABRE element that cools the hot airstream generated by air entering the engine intake at hypersonic speed.
“This is not only an excellent achievement in its own right but one important step closer to demonstrating the feasibility of the entire SABRE engine concept,” said Mark Ford, heading ESA’s Propulsion Engineering section.

US Air Force gets its first anti-drone laser weapon from Raytheon
Posted by Klaus Baldauf in categories: drones, military
Raytheon has delivered the first anti-drone buggy to the US Air Force, just over year after it introduced the technology. It’s a high-energy laser system mounted on a small all-terrain vehicle, to be specific, which uses electro-optical/infrared sensors to detect and track drones. After it identifies and tracks the unwelcome flying device, it then neutralizes it with its laser in a process that takes a few seconds.

Rivian: A look at the company selling Amazon 100,000 electric vans
Posted by Omuterema Akhahenda in category: transportation
DETROIT — Electric vehicle startup Rivian Automotive got a big boost from one of its investors on Thursday when Amazon.com announced it was ordering 100,000 electric delivery vans.
Before Rivian has even begun commercial production at its factory in Normal, Illinois, the Amazon order rocketed it to the forefront of electric vehicle makers.
Amazon Chief Executive Jeff Bezos said in Washington that as part of the online retailer’s plan to be carbon neutral by 2040 it would order the electric vans from Rivian, with deliveries starting in 2021. The goal is to deploy all the vehicles by 2024.

ITT Cannon Presents Liquid-Cooled HPC Plug For 500A At 1,000V
Posted by Omuterema Akhahenda in categories: energy, transportation
A bit old news.
As the fast charging infrastructure progresses towards 150–350 kW power levels (for passenger cars and beyond in case of bigger vehicles), also plug/connector suppliers try to keep pace with change.
Here we see one of the ITT Cannon DC fast charging plugs, presented at the eMove360° fairs in Munich, Germany.

Did Google Just Achieve ‘Quantum Supremacy’?
Posted by Michael Dodd in categories: computing, quantum physics
Is Google moving past the rest of the competition.
Quantum computers’ potential and the advantages they promise over classical computers all remain largely theoretical, and hypothetically speaking, it is predicted that quantum computers will be able to solve problems that are beyond the reach of the classical computers we use today. Passing such a threshold will be considered proof of what we call “quantum supremacy.”
