Physicists just discovered a totally new form of light

Physicists have just discovered a new form of light that doesn’t follow our existing rules of angular momentum, and it could shake up our understanding of the electromagnetic radiation and lead to faster, more secure optical communication.

Because of how well-studied and, well, everywhere, light is, you might assume that we’ve pretty much learnt all there is to know about it. But just last year, researchers identified a fundamental new property of light, and now a team of Irish scientists has shown that light can take on unexpected new forms.

One of the ways we measure a beam of light is through its angular momentum — a constant quantity that measures how much light is rotating. And until now, it was thought that for all forms of light, the angular momentum would be a whole number (known as an integer) multiple of Planck’s constant — a physical constant that sets the scale of quantum effects.

The existence of massive particles of light could finally explain dark energy

In the late 1990s, astronomers discovered something mysterious pushing galaxies apart faster than gravity pulls them together. It seemed like every little bit of space had some amount of energy that spread it away from every other little bit of space, and that strange pushing came to be known as ‘dark energy’ — dark, because no one knows what it is.

And now a group of physicists have shown that dark energy could probably be explained — as long as we’re willing to give up a fundamental piece of our understanding of light…

Most scientists think that dark energy exists because of what’s known as a cosmological constant — something acting throughout the Universe that tells different bits of space to repel each other. It’s sort of like an anti-gravity force, but it acts everywhere instead of just being between two things with mass and it always acts with the same strength.

Innovative Bio-glass Could Re-grow Cartilage

Why biocomputing is proving that bio and technology integrated can do amazing things and will eventually get us to real Singularity. Now imaging, take what you have seen so far in technology today and add Quantum to that picture then add bio to that; then you will truly see amazing SINGULARITY.

Scientists have developed a material that can mimic cartilage and potentially encourage it to re-grow.

Cartilage is flexible connective tissue found in places such as in joints and between vertebrae in the spine. Compared to other types of connective tissue is not easy to repair.

The researchers from Imperial College London and the University of Milano-Bicocca have developed a bio-glass material that mimics the shock-absorbing and load bearing qualities of real cartilage. It can be formulated to exhibit different properties, and they are now hoping to use it to develop implants for replacing damaged cartilage discs between vertebrae.

Looking toward the quantum-technology landscape of the future

Quantum future discussed at London’s Royal Society Conference.

By Tushna Commissariat

Not a week goes by here at Physics World that we don’t cover some advance in quantum mechanics – be it another step towards quantum computing or error correction, or a new type of quantum sensor, or another basic principle being verified and tested at new scales. While each advance may not always be a breakthrough, it is fair to say that the field has grown by leaps and bound in the last 20 years or so. Indeed, it has seen at least two “revolutions” since it first began and is now poised on the brink of a third, as scientific groups and companies around the world race to build the first quantum computer.

With this in mind, some of the stalwarts of the field – including Peter Knight, Ian Walmsley, Gerard Milburn, Stephen Till and Jonathan Pritchard – organized a two-day discussion meeting at the Royal Society in London, titled “Quantum technology for the 21st century “, which I decided to attend. The meeting’s main aim was to bring together academic and industry leaders “in quantum physics and engineering to identify the next generation of quantum technologies for translational development”. As Knight said during his opening speech, the time has come to “balance the massive leaps that the science has made with actual practical technology”.

Lego-like electronic bricks redefines ‘playing with blocks’

Interesting method in controlling energy sources and efficiencies via Quantum legos.

The chrome-plated bricks can conduct electricity, integrate active parts such as LED lights, motor blocks, and even sound, light and proximity sensors. The conductive bricks feature flexible side-arms that ensure electrical connection between two adjacent blocks, and the whole assemblies are powered by a Bluetooth-controlled 9V battery block. The built-in Bluetooth controller lets users change the current’s direction and voltage levels via a mobile application.

That means the Brixo bricks can not only be triggered by sound, light and touch, but also controlled by any Bluetooth connected device, taking the good old Lego bricks further into the IoT world (the Danish company has its entries in the cloud via its Mindstorms Lego series and the augmented reality-capable Nexo Knights toys.

The company is promising open 3D building instructions, an online library of models and hacks to its followers, encouraging a community of Brixo enthusiasts to share their models.

Advisory Committee expresses Quantum, legacy system concerns

NSA meets with Silicon Valley execs to voice their concerns over legacy systems being hacked by Quantum technology. Glad they’re talking about it because with the recent advancements in Quantum means it will be available in devices, communications, and platforms a lot sooner than originally projected.

The National Security Telecommunications Advisory Committee (NSTAC) brought together Silicon Valley executives with federal officials at the advisory committee’s annual meeting on Wednesday in Santa Clara, California.

U.S. military and intelligence officials, including Department of Defense Secretary Ash Carter, Department of Homeland Security Secretary Jeh Johnson, and Department of Commerce Secretary Penny Pritzker, attended the advisory committee.

“Today’s era relies on technological innovation in our field such as speed and agility,” said Defense Secretary Carter at the meeting. During his presentation, he introduced Raj Shah, CEO/co-founder of Morta Security, Air Force Reservist, and former F-16 pilot, to lead the Defense Department’s Defense Innovation Unit Experimental (DIUX) initiative. The DoD is restructuring the DIUX program, a Silicon Valley outreach initiative, with Carter calling the revised program “DIUX 2.0.” Shah’s security firm, Morta Security, was acquired by Palo Alto Networks in March 2014.

Quantum research that could enhance self-driving vehicles now a $6M commercial venture

I am so happy to see others seeing the value because Quantum is changing everything; not just computing, raw material enrichment, medical technology and treatments, etc. Once more and more folks start seeing the various capabilities around Quantum and just how wide that range is; we will begin to see an explosion of demand for Quantum. We’re still in that mode of discovery, and wait and see state by some. However, the Quantum Revolution will exceed even the industrial revolution with the span of change that it brings across so many areas & industries.

Quantum physics research that could enhance self-driving vehicles and spearheaded by a Dalhousie University team is now a $6-million commercial venture that counts U.S. aerospace giant Lockheed Martin among its partners.

What started as a theoretical research project backed by Lockheed Martin hit paydirt when physics professor Jordan Kyriakidis realized quantum software could be used to perfect the design and operation of self-driving cars and new aircraft.

“A self-driving car is an example of a machine that’s really an infrastructure that is going to be entrusted with our lives and our children’s lives, so it’s absolutely critical that the machine behaves exactly as intended, doesn’t have any flaws, and so our software helps ensure that, before they even build anything, when it’s still at the blueprint stage,” said Kyriakidis, now CEO of Halifax-based Quantum Research Analytics (QRA).

How toy street lamps are shedding new light on quantum computing

“ALL ABOARD” the QC train is leaving the station.

If you’ve ever had a train set, you might remember the tiny street lamps that are often part of the model landscape. Today, the bulbs from those toy lamps are helping to shed light on quantum computing.

In fact, there’s been a spate of developments lately in quantum computing, and not just IBM’s announcement of its upcoming cloud service. Here are three recent advances from research institutions around the world.

Scientists take a major leap toward a ‘perfect’ quantum metamaterial

Scientists have devised a way to build a “quantum metamaterial” — an engineered material with exotic properties not found in nature — using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.

The research team, led by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, proposes the use of an accordion-like atomic framework, or “lattice” structure, made with laser light to trap atoms in regularly spaced nanoscale pockets. Such a light-based structure, which has patterned features that in some ways resemble those of a crystal, is essentially a “perfect” structure — free of the typical defects found in natural materials.

Researchers believe they can pinpoint the placement of a so-called “probe” atom in this crystal of light, and actively tune its behavior with another type of laser light (near-infrared light) to make the atom cough up some of its energy on demand in the form of a particle of light, or photon.
