Machine-learning technique used to pinpoint quantum errors

Posted by in categories: information science, quantum physics, robotics/AI

Researchers at the University of Sydney and quantum control startup Q-CTRL today announced a way to identify sources of error in quantum computers through machine learning, providing hardware developers the ability to pinpoint performance degradation with unprecedented accuracy and accelerate paths to useful quantum computers.

A joint scientific paper detailing the research, titled “Quantum Oscillator Noise Spectroscopy via Displaced Cat States,” has been published in the Physical Review Letters, the world’s premier physical science research journal and flagship publication of the American Physical Society (APS Physics).

Focused on reducing errors caused by environmental “noise”—the Achilles’ heel of —the University of Sydney team developed a technique to detect the tiniest deviations from the precise conditions needed to execute quantum algorithms using trapped ion and superconducting quantum computing hardware. These are the core technologies used by world-leading industrial quantum computing efforts at IBM, Google, Honeywell, IonQ, and others.

A single-molecule laser nanospectroscopy technique with micro-electron volt energy resolution

Posted by in categories: chemistry, computing, nanotechnology

When molecules are excited, they can give rise to a variety of energy conversion phenomena, such as light emission and photoelectric or photochemical conversion. To unlock new energy conversion functions in organic materials, researchers should be able to understand the nature of a material’s excited state and control it.

So far, many scientists have used spectroscopy techniques based on in research focusing on excited states. Nonetheless, they were unable to use light to examine nanoscale materials, due to its limitations in so-called diffraction. The spectroscopic measurement methods applied to electron and scanning probe microscopes that can observe substances with atomic resolutions, on the other hand, are still underdeveloped.

Researchers at RIKEN, the Japan Science and Technology Agency (JST), University of Tokyo and other Institutes in Japan have recently developed a laser nanospectroscopy technique that could be used to examine individual molecules. This technique, presented in a paper published in Science, could open up new possibilities for the development of various new technologies, including light-emitting diodes (LEDs), photovoltaics and photosynthetic cells.

A ‘Very Exciting’ unique exoplanet has more water than earth

Posted by in category: space

The CHEOPS satellite accidentally spotted a rare exoplanet with no known equivalent. The satellite detected this unique exoplanet while looking for two exoplanets in a bright nearby star system.

This planet called ‘Nu2 Lupi d’ is located 50 light-years away in the constellation Lupus (Latin for Wolf), around a star called Nu2 Lupi. It is about 2.5 times the size of Earth and almost 9 times its mass.

What’s more, scientists used measurements with archival data from other observatories and numerical models to characterize the density and composition of the planet and its neighbors. They found that the planet has a rocky interior. It has far more water than the Earth. However, the water is not liquid; instead of taking high-pressure ice or high-temperature steam, making the planets uninhabitable.

Jeff Bezos Offers NASA $2bn In Exchange For Moon Contract For Blue Origin To Land Astronauts In Space

Posted by in category: space travel

First of all the title is highly misleading and directly contradicted by the article itself and the actual letter. (He’s not ‘offering’ NASA money he’s voluntarily forgoing payment equal to the SpaceX award for the contract. Now considering the initial pricing was closer to 10 billion that would essentially mean that NASA would be on the hook for about 8 billion but considering the total SpaceX contract is also about 10 billion that still fits into the new Congressional budget, if barely) Secondly considering that Blue Origin is only one of the companies that are cooperating to this bid if the other companies do no agree they he actually WILL be paying those companies to participate. Thirdly while the overall concept was rejected it pays to keep in mind it was ONLY rejected for the price and some questions on the proposed engine development budget so this goes a long way to show they are putting more ‘skin’ in the game than SpaceX. So interesting but highly disappointing ‘take’ on the offer by VT.


Jeff Bezos has offered NASA $2 billion in exchange for a moon contract that will allow Blue Origin to land astronauts in space. The Amazon founder, 57, made history when he went to space last week, and now in an open letter to administrator Bill Nelson on July 26, he…

DeepMind says it can predict the shape of every protein in the human body

Posted by in categories: biotech/medical, robotics/AI

The predicted shapes still need to be confirmed in the lab, Ellis told Technology Review. If the results hold up, they will rapidly push forward the study of the proteome, or the proteins in a given organism. DeepMind researchers published their open-source code and laid out the method in two peer-reviewed papers published in Nature last week.


And in 20 other animals often studied by science, too.

2-legged robot developed at Oregon State makes history by completing a 5K

Posted by in category: robotics/AI

CORVALLIS, Ore. – A two-legged robot invented at Oregon State University completed a 5K in just over 52 minutes. Cassie the robot, created by OSU spinout company Agility Robotics, made history with the successful trot. “Cassie, the first bipedal robot to use machine learning to control a running gait on outdoor terrain, completed the 5K on Oregon State’s campus untethered and on a single battery charge,” according to OSU. But it didn’t go off without a hitch.

World’s cheapest energy storage will be an iron-air battery, says Jeff Bezos-backed start-up

Posted by in categories: chemistry, energy

Form Energy, the billionaire-backed start-up that claimed to have developed an innovative low-cost 150-hour battery, has finally revealed its battery chemistry after more than a year of high-profile secrecy.

The Boston-based company says its first commercial product is a “rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than 1/10th the cost of lithium-ion”.

Melinda French Gates and McKenzie Scott team up to give $40 million to support women

Posted by in categories: business, finance

French Gates and Scott, who were formerly married to Seattle-based tech founders Bill Gates and Jeff Bezos, respectively, have become powerful philanthropists in their own rights. Both women, who are among the richest people in the world, have signed The Giving Pledge, promising to give away the majority of their wealth in their lifetimes.


In a powerful philanthropic pairing, Melinda French Gates and McKenzie Scott have teamed up to direct $40 million to advancing the power and influence of American women over the next decade.

The donation is being awarded to winners of the Equality Can’t Wait Challenge, a competition hosted by French Gates’ investment firm Pivotal Ventures, with financial support from Scott and her husband, Dan Jewett, as well as from the Charles and Lynn Schusterman Family Philanthropies. The challenge billed itself as “the first competition centered on gender and equality in the U.S. with an award of this magnitude and … an opportunity to invest in and empower women leaders.”

Electric boat startup Arc wants to make a big splash

Posted by in categories: space travel, sustainability

But does it want to be the “Tesla of boats?”


A new startup called Arc wants to revolutionize the boating world with a battery-powered craft made for watersports. The small startup, which employs a handful of former SpaceX employees, has designed a sharp but pricey boat with a big battery and an aluminum hull.
