Building a silicon quantum computer chip atom

Posted by in categories: computing, engineering, particle physics, quantum physics

A University of Melbourne-led team has perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given us cheap and reliable conventional devices containing billions of transistors.

“We could ‘hear’ the electronic click as each atom dropped into one of 10,000 sites in our prototype device. Our vision is to use this technique to build a very, very large-scale quantum device,” says Professor David Jamieson of The University of Melbourne, lead author of the Advanced Materials paper describing the process.

Dimming the Sun Could Spell Doom for Humanity, Experts Warn

Posted by in categories: climatology, engineering, policy, sustainability

Policy experts and scientists are coming together to stop such experimentation.

Back in March of 2021, we brought you news of a study from the Bill Gates-backed Harvard University Solar Geoengineering Research Program which aimed to evaluate the efficacy of blocking sunlight from reaching our planet’s surface in order to delay the effects of climate change.

Now, more than 60 policy experts and scientists have come together to claim that these kinds of geoengineering initiatives are very dangerous for humanity, according to

Researchers from DARPA, NASA and MIT working to develop Anti-Gravity technologies

Posted by in categories: engineering, transportation

Anyone able to find the sources? 🤔

Antigravity is the concept of a technology that, when applied to an item or a place, allows it to “cancel” gravity rather than compensate for it, as in the case of an aircraft.

Since November 2020, a group of experts from NASA, DARPA, MIT, and the Air Force has met on Zoom on a monthly basis to explore future propulsion technology, including the possible “antigravity.” Given that this technology now exists only in science fiction or in the thoughts of a few dreamer thinkers, this is a remarkable occurrence.

James Webb Space Telescope reaches major milestone as primary mirror unfolds

Posted by in categories: alien life, engineering

As of Jan. 8, 2022, NASA’s (Washington D.C., U.S.) James Webb Space Telescope (JWST) team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments (including the 70-foot sunshield) since its Dec. 25 launch, to prepare for science operations. The telescope makes ample use of composite materials.

A joint effort with the European Space Agency (ESA) and Canadian Space Agency (CSA), the Webb mission will explore every phase of cosmic history, from within our solar system to the most distant observable galaxies in the early universe.

Architects Design Ferry Terminal That Resembles an Alien World

Posted by in category: engineering

The design team was inspired by the orange gantry cranes at the freight terminal.

It’s no surprise that we love architecture and engineering marvels. In the past, we have brought you lists of architectural marvels that seem to defy the laws of science and the most interesting engineering designs around the world.

Now, we are bringing you an incredible creation from MAD Architects, led by Ma Yansong, in collaboration with the China Academy of Building Research (CASR). Together these organizations have won an international competition for the design of the Cuntan International Cruise Centre in Chongqing, China and its execution is a sight to behold.

New Mach 5 Hypersonic Scramjet Is Powered by Sustainable Green Hydrogen

Posted by in categories: engineering, satellites, sustainability

It’s rare that faster can also equate to greener in the aerospace industry, but that’s the goal of Australian startup Hypersonix has in sight.

The company has developed a new hypersonic satellite launch system that will make launches more accessible and also more sustainable. The technology could one day also help develop hypersonic airliners capable of crossing the Atlantic in a little over an hour.

“At Mach 5 and above, friction caused by molecules flowing over the hypersonic aircraft can generate temperatures in excess of 2,000˚C (3,632˚F),” the company says in a press statement. “Suffice to say that Brisbane-based aerospace engineering start-up, Hypersonix Launch Systems, is choosing its materials to cope with these extremes.”

Shrinking qubits for quantum computing with atom-thin materials

Posted by in categories: computing, engineering, particle physics, quantum physics

For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. Achieving this, however, has come at the cost of size. Whereas the transistors used in classical computers have been shrunk down to nanometer scales, superconducting qubits these days are still measured in millimeters—one millimeter is one million nanometers.

Combine qubits together into larger and larger circuit chips, and you end up with, relatively speaking, a big physical footprint, which means quantum computers take up a lot of physical space. These are not yet devices we can carry in our backpacks or wear on our wrists.

To shrink qubits down while maintaining their performance, the field needs a new way to build the capacitors that store the energy that “powers” the qubits. In collaboration with Raytheon BBN Technologies, Wang Fong-Jen Professor James Hone’s lab at Columbia Engineering recently demonstrated a superconducting qubit built with 2D materials that’s a fraction of previous sizes.

Exploring Tesla Model S High Voltage Cabling

Posted by in categories: education, engineering, sustainability, transportation

When he’s not busy with his day job as professor of computer and automotive engineering at Weber State University, [John Kelly] is a prolific producer of educational videos. We found his video tracing out the 22+ meters of high voltage cabling in a Tesla Model S (below the break) quite interesting. [John] does warn that his videos are highly detailed and may not be for everyone:

This is not the Disney Channel. If you are looking to be entertained, this is not the channel for you.

Russia’s Tu-160M strategic missile carrier made its first flight

Posted by in categories: engineering, transportation

Russia’s first newly manufactured Tupolev Tu-160M strategic missile carrier made its first flight on 12 January. The flight – performed at the airfield of the Kazan Aviation Plant – took place at an altitude of 600 meters and lasted about 30 minutes. The crew of test pilots of Tupolev PJSC performed maneuvers to check the stability and controllability of the aircraft in the air. It comes under the umbrella of the United Aircraft Corporation, UAC, part of the state-owned Rostec entity.

The program for the reproduction of Tu-160 aircraft in the modernized form of the Tu-160M is a part of a state contract between the Ministry of Industry and Trade of Russia and Tupolev. As a part of the program, the design documentation for the Tu-160M aircraft was completely digitized in a short time, the technology for vacuum welding of titanium products was restored, the production of aircraft airframe units was resumed. Also, new cooperation was formed from advanced industrial enterprises in the field of metallurgy, aircraft manufacturing, mechanical engineering, and instrument making.

The team has restored the full production cycle of the Tu-160, but in the M modification, using modernized engines, modernized aircraft control systems, navigation systems, weapons control systems. The modernization of the Kazan Aviation Plant played an important role in restoring the production of unique aircraft. The aircraft retains its appearance but is created on a completely new technological base using digital technologies.
