By adding some magnetic flair to an exotic quantum experiment, physicists produced an ultra-stable one-dimensional quantum gas with never-before-seen “scar” states – a feature that could someday be useful for securing quantum information.

As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his name. It was a machine consisting of a screw housed inside a hollow tube that trapped and drew water upon rotation. Now, researchers led by Stanford University physicist Benjamin Lev have developed a quantum version of Archimedes’ screw that, instead of water, hauls fragile collections of gas atoms to higher and higher energy states without collapsing. Their discovery is detailed in a paper published today (January 142021) in Science.

In a brief announcement today, the Canadian nuclear fusion technology developer General Fusion announced that the investment firm created by Shopify founder Tobias Lütke has joined the company’s cap table.

The size of the investment made by Lütke’s Thistledown Capital was not disclosed, but with the addition, General Fusion has the founders of the two biggest e-commerce companies in the Western world on its cap table.

Jeff Bezos, the founder and chief executive of Amazon, first invested in the company nearly a decade ago and General Fusion has been steadily raising cash since that time. In 2019, the company hauled in $100 million. That capital commitment is part of a haul totaling at least, $192 million, according to Crunchbase although the real figure is likely higher.

One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with French microelectronics leader CEA-Leti, has been exploring everyday transistors — that are present in billions in all our mobile phones — for their use as qubits.

The French company Leti makes giant wafers full of devices, and, after measuring, researchers at the Niels Bohr Institute, University of Copenhagen, have found these industrially produced devices to be suitable as a qubit platform capable of moving to the second dimension, a significant step for a working quantum computer. The result is now published in Nature Communications.

One of the key features of the devices is the two-dimensional array of quantum dot. Or more precisely, a two by two lattice of quantum dots. “What we have shown is that we can realize single electron control in every single one of these quantum dots. This is very important for the development of a qubit, because one of the possible ways of making qubits is to use the spin of a single electron. So reaching this goal of controlling the single electrons and doing it in a 2D array of quantum dots was very important for us,” says Fabio Ansaloni, former PhD student, now postdoc at center for Quantum Devices, NBI.

(SPHEREx) mission is a planned two-year mission funded at $242 million (not including launch costs).

SPHEREx will survey the sky in optical as well as near-infrared light which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way.

SPHEREx will survey hundreds of millions of galaxies near and far, some so distant their light has taken 10 billion years to reach Earth. In the Milky Way, the mission will search for water and organic molecules — essentials for life, as we know it — in stellar nurseries, regions where stars are born from gas and dust, as well as disks around stars where new planets could be forming.

In 2012, the Gateway Foundation was founded with the purpose of building the world’s first rotating space station in orbit – known as The Gateway. This is no easy task and must be preceded by establishing the necessary infrastructure in orbit and the creation of a series of smaller structures to test the concept. This includes the Voyager Class station, a rotating structure designed to produce varying levels of artificial gravity.

In recent months, the Orbital Assembly Corporation (OAC) – founed in 2018 by the Gateway team – began working on a crucial component, known as the DSTAR. These and other updates about their Voyager Class station were the subjects of a recent video featuring Foundation and OAC CEO John Blincow. According to Blincow, he and his colleagues will be performing a demonstration and making a big announcement in the coming weeks!

The design for The Gateway was inspired by the Von Braun Wheel, a proposal made by German rocket scientist and space architect Wernher von Braun. This, in turn, was inspired by earlier concepts like the pinwheel space station prosed by Russian scientist and “father of astronautics” Konstantin Tsiolkovsky. In 1903, he released a treatise titled, Exploration of Outer Space by Means of Rocket Devices.
