New design principles for spin-based quantum materials

As our lives become increasingly intertwined with technology—whether supporting communication while working remotely or streaming our favorite show—so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint—and consume 200 terawatt hours of energy each year, greater than the annual energy consumption of Iran. To balance ecological concerns yet meet growing demand, advances in microelectronic processors—the backbone of many Internet of Things (IoT) devices and data hubs—must be efficient and environmentally friendly.

Northwestern University materials scientists have developed new design principles that could help spur development of future quantum materials used to advance (IoT) devices and other resource-intensive technologies while limiting ecological damage.

“New path-breaking materials and computing paradigms are required to make more energy-lean in the future,” said James Rondinelli, professor of materials science and engineering and the Morris E. Fine Professor in Materials and Manufacturing at the McCormick School of Engineering, who led the research.

Starlink puts towns devastated by wildfires online for disaster relief workers

SpaceX’s Starlink has showed its utility in connecting far-flung locations to the internet quickly and relatively simply in Washington, where like much of the west coast wildfires have caused enormous damage to rural areas. A couple small towns in the state have received Starlink connections to help locals and emergency workers.

The town of Malden was almost completely destroyed, but restoration efforts are underway, and of course it helps to be able to access the internet for communicating with residents and authorities. With power and cellular service unreliable, satellite internet is a good temporary option, and Starlink stepped up.

As SpaceX founder Elon Musk said on Twitter, the company is prioritizing emergency responders and areas without internet:

‘Schrödinger’s Web’ offers a sneak peek at the quantum internet

Quantum computers, which harness the strange probabilities of quantum mechanics, may prove revolutionary. They have the potential to achieve an exponential speedup over their classical counterparts, at least when it comes to solving some problems. But for now, these computers are still in their infancy, useful for only a few applications, just as the first digital computers were in the 1940s. So isn’t a book about the communications network that will link quantum computers — the quantum internet — more than a little ahead of itself?

Surprisingly, no. As theoretical physicist Jonathan Dowling makes clear in Schrödinger’s Web, early versions of the quantum internet are here already — for example, quantum communication has been taking place between Beijing and Shanghai via fiber-optic cables since 2016 — and more are coming fast. So now is the perfect time to read up.

Dowling, who helped found the U.S. government’s quantum computing program in the 1990s, is the perfect guide. Armed with a seemingly endless supply of outrageous anecdotes, memorable analogies, puns and quips, he makes the thorny theoretical details of the quantum internet both entertaining and accessible.

Readers wanting to dive right in to details of the quantum internet will have to be patient. “Photons are the particles that will power the quantum internet, so we had better be sure we know what the heck they are,” Dowling writes. Accordingly, the first third of the book is a historical overview of light, from Newton’s 17th century idea of light as “corpuscles” to experiments probing the quantum reality of photons, or particles of light, in the late 20th century. There are some small historical inaccuracies — the section on the Danish physicist Hans Christian Ørsted repeats an apocryphal tale about his “serendipitous” discovery of the link between electricity and magnetism — and the footnotes rely too much on Wikipedia. But Dowling accomplishes what he sets out to do: Help readers develop an understanding of the quantum nature of light.

For an entertaining overview of the physics and technological advances paving the way for the quantum internet, read ‘Schrödinger’s Web.’

Elon Musk says he likely will take Starlink satellite internet service public in ‘several years’

SpaceX CEO Elon Musk on Monday reiterated the likelihood that his private space company will likely take its Starlink satellite internet service public in the coming years.

“We will probably IPO Starlink, but only several years in the future when revenue growth is smooth & predictable,” Musk said in a tweet. “Public market does not like erratic cash flow haha.”

SpaceX leadership has previously discussed the idea, with company President Gwynne Shotwell in February telling a group of investors in February that “Starlink is the right kind of business that we can go ahead and take public,” adding that the company could spin it off.

U.S. judge sends OneWeb’s rescue plan to vote and okays financing

Berlin, 27 September 2020. – A New York bankruptcy judge has sent OneWeb’s Chapter 11 plan for creditor vote and approved OneWeb’s financing plan, Law360 reported.

“A New York bankruptcy judge on Wednesday sent OneWeb Global’s $181 million equity-swap Chapter 11 plan to a creditor vote while approving $235 million in new financing that the satellite internet startup said will go toward restarting its launch program,” Law 360 reported.

According to the report, OneWeb’s counsel told U.S. Bankruptcy Judge Robert Drain that it had secured full creditor consent for the plan.

U.S. Air Force Acquisition Chief is impressed by SpaceX Starlink’s performance during Live-Fire exercise

The United States Air Force signed a deal with SpaceX valued at around $28 million in 2018, to assess the Starlink network’s performance on military platforms. The Air Force is actively experimenting with how space-based internet could enhance Multi-Domain Operations (MDO). These operations require moving vast quantities of data between the five domains of warfare: ground, sea, sky, outer space, and cyberspace. The military needs a reliable communication system at all times to protect and defend the country from potential threats. The assessment of Starlink will offer the military insight on whether it should purchase Starlink service long-term.

U.S. Air Force Chief for Acquisition Dr. Will Roper, who serves as the principal adviser for technology research and development, met with reporters to discuss a live-fire military exercise that took place early this month, Investors news reports. During the conference, Roper shared SpaceX’s Starlink network was tested during the live-fire exercise as part of the military’s Advanced Battle Management System (ABMS). – “What I’ve seen from Starlink has been impressive and positive,” he told reporters on Wednesday. “They’re cleverly engineered satellites cleverly deployed. So, there’s a lot to learn from how they’re designed and I think that there’s a lot we can learn from them.”

Roper shared that the Air Force connected Starlink to a “variety of air and terrestrial assets”. Starlink terminals are hooked to the cockpit of a Boeing (BA) KC-135 Stratotanker aircraft to assess the network’s performance while the airplanes fly.

Starlink packet routing

Part of my series countering common misconceptions in space journalism.

This blog is a follow on to my original post on Starlink. Starlink is an emerging high performance satellite-based internet routing network developed by SpaceX. Its ultimate purpose is to become the de-facto internet backbone provider, connect billions more people to the internet, and revolutionize access to space.

The usual disclaimers apply. I have no relevant inside knowledge of Starlink operations. I’m not an expert in networking, and unlike Starlink’s staff I haven’t spent years working only on this problem. In fact, I’m usually deeply confused at the best of times. But I had a cool idea and I wanted to share it.
