A new supercomputer has been deployed at the Jülich Supercomputing Center (JSC) in Germany. Called QPACE3, the new 447 Teraflop machine is named for “QCD Parallel Computing on the Cell.”

QPACE3 is being used by the University of Regensburg for a joint research project with the University of Wuppertal and the Jülich Supercomputing Center for numerical simulations of quantum chromodynamics (QCD), which is one of the fundamental theories of elementary particle physics. Such simulations serve, among other things, to understand the state of the universe shortly after the Big Bang, for which a very high computing power is required.

The demand for high performance computers to solve complex applications has risen exponentially, but unfortunately so has their consumption of power. Many supercomputers require more than a megawatt of electricity to operate and annual electricity costs can easily run into millions of Euros. The energy supply is therefore a significant part of the operating costs of a data center. According to recent analyst studies, this represents the second-largest factor in addition to personnel and maintenance costs. The upcoming boom with (3D) video streaming, augmented reality, image recognition and artificial intelligence is driving up the demand for data center capabilities, thereby placing new challenges in the power supply sector.

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe’s existence, known as primordial black holes.

Excellent.

Researchers at Tohoku University have, for the first time, successfully demonstrated the basic operation of spintronics-based artificial intelligence.

Artificial intelligence, which emulates the information processing function of the brain that can quickly execute complex and complicated tasks such as image recognition and weather prediction, has attracted growing attention and has already been partly put to practical use.

In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.

The research, published in the journal Science and conducted at Princeton and HRL Laboratories in Malibu, California, represents a more than five-year effort to build a robust capability for an electron to talk to a photon, said Jason Petta, a Princeton professor of physics.

“Just like in human interactions, to have good communication a number of things need to work out—it helps to speak the same language and so forth,” Petta said. “We are able to bring the energy of the electronic state into resonance with the light particle, so that the two can talk to each other.”

Happy Holidays; happy end of the year, happy launch of next year, happy snow days, happy hot chocolate day, etc. Nonetheless, my gift to you this year is a Nanoscale Snowman.

Would a jewel-encrusted snowman make the perfect Christmas present? At only 5 nanometres in size, the price might be lower than you think. And it’s functional too, catalysing the splitting of water to make green hydrogen for fuel cells.

The nanoparticle, as imaged with the aberration-corrected scanning transmission electron microscopes, features eyes, nose and mouth of precious-metal platinum clusters embedded in a titanium dioxide face. Each platinum cluster typically contains 30 platinum atoms; within the whole nanoparticle there are approximately 1680 titanium atoms and 180 platinum atoms.

Nice.

Scientists have enlisted the exotic properties of graphene, a one-atom-thick layer of carbon, to function like the film of an incredibly sensitive camera system in visually mapping tiny electric fields in a liquid. Researchers hope the new method will allow more extensive and precise imaging of the electrical signaling networks in our hearts and brains.

The ability to visually depict the strength and motion of very faint electrical fields could also aid in the development of so-called lab-on-a-chip devices that use very small quantities of fluids on a microchip-like platform to diagnose disease or aid in drug development, for example, or that automate a range of other biological and chemical analyses. The setup could potentially be adapted for sensing or trapping specific chemicals, too, and for studies of light-based electronics (a field known as optoelectronics).

Oh; there is a LOT more to they syndiamond story as it relates to some of the additional hardware and communications technologies that we’re developing and planning for the future.

What are the unique properties of diamond that make it a supermaterial?

Diamond has long been known to have exceptional properties, largely resulting from the symmetry of the cubic lattice made of light carbon atoms connected by extremely strong bonds. These exceptional properties include thermal conductivity five times higher than that of copper and the widest optical transparency of any material extending from the UV to the RF part of the electromagnetic spectrum. Additionally, diamond also has some interesting chemical properties as it is extremely inert, though it can become a conductor by adding boron. In this manner, one could leverage synthetic diamond for use in electrochemical incineration where existing electrode materials have only a limited lifetime.

Nice.

Using their advanced atomic clock to mimic other desirable quantum systems, JILA physicists have caused atoms in a gas to behave as if they possess unusual magnetic properties long sought in harder-to-study solid materials. Representing a novel “off-label” use for atomic clocks, the research could lead to the creation of new materials for applications such as “spintronic” devices and quantum computers.

JILA’s record-setting atomic clock, in which strontium atoms are trapped in a laser grid known as an optical lattice, turns out to be an excellent model for the magnetic behavior of crystalline solids at the atomic scale. Such models are valuable for studying the counterintuitive rules of quantum mechanics.

Back in September 2015, Gooch & Housego reported on our work with cold atom technology on the FreezeRay project. Now, just over a year later, we’re happy to say that Gooch & Housego has successfully won funding for involvement in two further programs, CASPA and REVEAL, in a competition for the commercialization of quantum technologies. The contest is supported by Innovate UK and the UK National Quantum Technologies Programme.

CASPA (Cold Atom Space Payload) has the aim of developing a payload compatible with CubeSat and capable of producing cold atoms in space. As with all such projects, we are breaking new ground here and an effective demonstration of the prototype system – in this instance space will be the crucial first step towards commercializing instrumentation systems capable of recording minuscule changes in the earth’s gravitational strength. Such changes when mapped across the earth’s surface have the potential to be used in resource exploration or to geo-monitoring of polar ice mass, ocean currents and sea level changes.

CASPA will also evaluate the viability of using the technology in the provision of higher precision timing sources for next generation global positioning system (GPS) and also for deep space navigation. The program partners are e2v technologies Ltd, ClydeSpace, XCAM, Covesion, the University of Birmingham and the University of Southampton.
