Quantum cloud computing with self-check

Posted by in categories: chemistry, computing, particle physics, quantum physics

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists first simulated the spontaneous formation of a pair of elementary particles with a digital quantum computer at the University of Innsbruck. Due to the error rate, however, more complex simulations would require a large number of quantum bits that are not yet available in today’s quantum computers. The analog simulation of quantum systems in a quantum computer also has narrow limits. Using a new method, researchers around Christian Kokail, Christine Maier und Rick van Bijnen at the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences have now surpassed these limits. They use a programmable ion trap quantum computer with 20 quantum bits as a quantum coprocessor, in which quantum mechanical calculations that reach the limits of classical computers are outsourced.

We are in the midst of an extinction crisis, warn UN scientists

Posted by in categories: existential risks, policy

The global rate of species extinction “is already tens to hundreds of times higher than it has been, on average, over the last 10 million years,” according to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), a UN committee, whose report was written by 145 experts from 50 countries.

One million of the planet’s eight million species are threatened with extinction by humans, scientists warned Monday in what is described as the most comprehensive assessment of global nature loss ever.

Their landmark report paints a bleak picture of a planet ravaged by an ever-growing human population, whose insatiable consumption is destroying the natural world.

New Horizons’ far-out findings from solar system’s Kuiper Belt turn into a cover story

Posted by in categories: materials, space travel

The space snowman known as 2014 MU69 or Ultima Thule added to its celebrity today by showing up on the cover of the journal Science, with the first peer-reviewed results from an encounter with NASA’s New Horizons spacecraft laid out within.

Close study of the two-lobed object — which orbits 4 billion miles from the sun within a sparse belt of icy material known as the Kuiper Belt — could shed light on how the solar system was formed, said New Horizons principal investigator Alan Stern, a planetary scientist at the Southwest Research Institute.

“We’re looking into the well-preserved remnants of the ancient past,” Stern said in a news release. “There is no doubt that the discoveries made about Ultima Thule are going to advance theories of solar system formation.”

Using Human “Wetware” to Control Robots

Posted by in category: robotics/AI

What happens when a man is merged with a computer or a robot? This is the question that Professor Kevin Warwick and his team at the department of Cybernetics, University of Reading in the UK have been trying to answer for a number of years.

There are many ways to look at this problem. There is the longer term prospect of freeing the mind from the limitations of the brain by uploading it in digital form, potentially onto a computer and/or robotic substrate (see the h+ interview with Dr. Bruce Katz, Will We Eventually Upload Our Minds?). There is also a shorter term prospect at a much more limited scale — a robot controlled by human brain cells could soon be wandering around Professor Warwick’s UK labs.

Atomically thin quantum light-emitting diodes

Posted by in categories: computing, quantum physics

Atomically thin transition metal dichalcogenides hold promise as scalable single-photon sources. Here, the authors demonstrate all-electrical, single-photon generation in tungsten disulphide and diselenide, achieving charge injection into the layers, containing quantum emitters.

Atomically thin light emitting device opens the possibility for ‘invisible’ displays

Posted by in categories: futurism, materials

The device opens the door to invisible displays on walls and windows – displays that would be bright when turned on but see-through when turned off — or in futuristic applications such as light-emitting tattoos, according to the researchers.

“The materials are so thin and flexible that the device can be made transparent and can conform to curved surfaces,” said Der-Hsien Lien, a postdoctoral fellow at UC Berkeley and a co-first author along with Matin Amani and Sujay Desai, both doctoral students in the Department of Electrical Engineering and Computer Sciences at Berkeley.

Their study was published March 26 in the journal Nature Communications. The work was funded by the National Science Foundation and the Department of Energy.
