Quantum sensors for high-precision magnetometry of superconductors

Posted by in categories: electronics, nanotechnology, quantum physics

Quantum Sensors enables precise imaging of magnetic fields of superconductors.


Scientists at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds as quantum sensors in a new kind of microscope to generate images of magnetic fields in superconductors with unrivaled precision. In this way the researchers were able to perform measurements that permit new insights in solid state physics, as they report in Nature Nanotechnology.

Researchers in the group led by the Georg-H. Endress Professor Patrick Maletinsky have been conducting research into so-called nitrogen-vacancy centers (NV centers) in diamonds for several years in order to use them as high-precision sensors. The NV centers are natural defects in the diamond crystal lattice. The electrons contained in the NVs can be excited and manipulated with light, and react sensitively to electrical and magnetic fields they are exposed to. It is the spin of these electrons that changes depending on the environment and that can be recorded using various measurement methods.

Maletinsky and his team have managed to place single NV spins at the tips of atomic force microscopes to perform nanoscale magnetic field imaging. So far, such analyses have always been conducted at room temperature. However, numerous fields of application require operation at temperatures close to absolute zero. Superconducting materials, for example, only develop their special properties at very low temperatures around −200°C. They then conduct electric currents without loss and can develop exotic magnetic properties with the formation of so-called vortices.

Vint Cerf: Buggy Software Is Scarier Than A Robot Takeover

Posted by in categories: cybercrime/malcode, internet, robotics/AI

Luv it!!!! Another fellow experienced AI SME having the same point of view that many other well seasoned AI experts have. Cerf is more concerned about coding bugs and not killer robots; and I and others are also concern about the weakness of the connected infrastructure, weak under pinning technology, and hacking/ criminals hotwiring or overriding AI systems to do their dirty deed and we’re not (like Cerf) concerned over robots and machines taking over the world.


Robots won’t take over humans, but buggy software might, according to the Google exec known as the “father of the Internet.”

Asked for his thoughts on the risk of a robotic overthrow, Google’s chief internet evangelist, Vint Cerf, said he doesn’t fear that problem — especially because artificial intelligence technology isn’t that sophisticated.

3 Newly Discovered Nearby Planets Are a Game Changer in The Hunt For Alien Life

Posted by in category: alien life

An international team of astronomers has discovered three Earth-sized exoplanets, all orbiting the same star just 40 light-years from us, the 16-nation intergovernmental research organization ESO reported on Monday.

The scientists have deemed all three planets potentially habitable, an exciting turn in the hunt for “exoplanets,” a term for planets that orbit a star other than our sun.

And it could bring us closer to finding extraterrestrial life.

Runner, 100, breaks the World Record for the 100-meter dash

Posted by in category: life extension

We’re all trying to discover immortaility through anti-aging. And, all of this time we had the perfect example running marathons. Would love to know her secret.


Ida Keeling continues to set a new mark for centenarians, breaking the World Record for the 100-yard dash for her age group (80 years and older) on Saturday in Philadelphia.

This Tiny Star Is Now the Best Place to Hunt for Alien Life

Posted by in category: alien life

In a few years, powerful new telescopes will usher in a search for habitable worlds outside our solar system. And TRAPPIST-1—a dim, tepid star just a smidge larger than Jupiter—is one of the first places we’ll look. It’s only forty light years away, and it’s home to several promising, Earth-sized exoplanets.

Three siblings, described today in the journal Nature, are the first exoplanets ever discovered around an “ultracool dwarf” star. And they’re a jackpot when it comes to the search for alien life. Each planet is similar in size to Earth or Venus and probably rocky. The planets all skirt the edge of the so-called habitable zone. Finally, these potential Earth twins are so close to us that we can begin studying their atmospheres right now.

“This is basically a paradigm shift,” study co-author Julien de Wit told Gizmodo. “If these planets have atmospheres, they really are the best places to look for life.”

Scientists turn skin cells into heart and brain cells using only drugs — no stem cells required

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

Neurons created from chemically induced neural stem cells. The cells were created from skin cells that were reprogrammed into neural stem cells using a cocktail of only nine chemicals. This is the first time cellular reprogramming has been accomplished without adding external genes to the cells. (credit: Mingliang Zhang, PhD, Gladstone Institutes)

Scientists at the Gladstone Institutes have used chemicals to transform skin cells into heart cells and brain cells, instead of adding external genes — making this accomplishment a breakthrough, according to the scientists.

Could Aluminum Nitride Be Engineered to Produce Quantum Bits?

Posted by in categories: encryption, quantum physics, supercomputing

Interesting insight on Aluminum Nitride used to create Qubits.

http:///articles/could-aluminum-nitride-be-engineered-to-pro…nteresting insight.


Newswise — Quantum computers have the potential to break common cryptography techniques, search huge datasets and simulate quantum systems in a fraction of the time it would take today’s computers. But before this can happen, engineers need to be able to harness the properties of quantum bits or qubits.
