Quantum experiments designed by machines

Posted by in categories: computing, information science, quantum physics

Very nice.

Quantum physicist Mario Krenn and his colleagues in the group of Anton Zeilinger from the Faculty of Physics at the University of Vienna and the Austrian Academy of Sciences have developed an algorithm which designs new useful quantum experiments. As the computer does not rely on human intuition, it finds novel unfamiliar solutions. The research has just been published in the journal Physical Review Letters. The idea was developed when the physicists wanted to create new quantum states in the laboratory, but were unable to conceive of methods to do so. “After many unsuccessful attempts to come up with an experimental implementation, we came to the conclusion that our intuition about these phenomena seems to be wrong. We realized that in the end we were just trying random arrangements of quantum building blocks. And that is what a computer can do as well — but thousands of times faster”, explains Mario Krenn, PhD student in Anton Zeilinger’s group and first author research.

After a few hours of calculation, their algorithm — which they call Melvin — found the recipe to the question they were unable to solve, and its structure surprised them. Zeilinger says: “Suppose I want build an experiment realizing a specific quantum state I am interested in. Then humans intuitively consider setups reflecting the symmetries of the state. Yet Melvin found out that the most simple realization can be asymmetric and therefore counterintuitive. A human would probably never come up with that solution.”

Defence white paper faces the reality of Australia’s engagement with Asia and the Pacific

Posted by in categories: computing, quantum physics, security

Australia’s improved alliance with China on defense, and Quantum Computing. Australia has been one of the early R&D groups working on Quantum Computing just like D-Wave, Stanford, UC Berkley, etc. So, this could help China drastically migrate much sooner to a Quantum infrastructure.

You think you’ve heard it before: Australia’s great security challenge this century is the dramatic shift in power to Asia epitomised by the rise of China.

But read of the latest Defence white paper if you want that abstract idea to sink in.

Quantum Algorithms and Their Discontents

Posted by in categories: chemistry, computing, information science, life extension, materials, neuroscience, quantum physics, robotics/AI, security, space

Interesting read; however, the author has limited his view to Quantum being only a computing solution when in fact it is much more. Quantum technology does offer faster processing power & better security; but, Quantum offers us Q-Dots which enables us to enrich medicines & other treatments, improves raw materials including fuels, even vegetation.

For the first time we have a science that cuts across all areas of technology, medical & biology, chemistry, manufacturing, etc. No other science has been able to achieve this like Quantum.

Also, the author in statements around being years off has some truth if we’re suggesting 7 yrs then I agree. However, more than 7 years I don’t agree especially with the results we are seeing in Quantum Networking.

Quantum physicists turn to the dark state

Posted by in categories: computing, quantum physics, transportation

“Suppose you want to travel from Helsinki to New York and you have to change your flight in London,” explains Sorin Paraoanu. “Normally you would first fly on a plane from Helsinki to London, then wait for some time in the airport in London, then board the flight London-New York. But in the quantum world, you would be better off boarding a plane from Helsinki to London sometime after the flight London-New York took off. You will not spend any time in London and you will arrive in New York right at the time when the plane from Hesinki lands in London.” This is mind-boggling but the experiment shows that it is indeed happening.

Besides the relevance for quantum computing, the result also has deep conceptual implications. Much of our understanding of the reality is based on the so-called continuity principle: the idea that influences propagate from here to there by going through all the places in-between. Real objects don’t just appear somewhere from nothing. But the experiment seems to defy this. Like in a great show of magic, quantum physics allows things to materialize here and there, apparently out of nowhere.

The team would like to acknowledge the excellent scientific environment created in the Low Temperature Laboratory (part of OtaNano) at the Department of Applied Physics.

Portland firm DARPA research could make disputes like Apple v FBI obsolete

Posted by in categories: computing, privacy

Portland computer science research company Galois snagged a $6.2 million grant from the Department of Defense for a project that, if successful, could make the current battle between the FBI and tech giant Apple obsolete.

The three-year research contract comes from the Defense Advanced Research Projects Agency and will fund research into quantifying privacy preservation systems.

‘Can you quantify how private a system is or isn’t and can you make a judgment about it,’ said Galois CEO Rob Wiltbank,…

Dx3 to Demonstrate How Artificial Intelligence Is the Future of Retail Innovations Like Pepper the Robot to Debut at Annual Tech Conference

Posted by in categories: computing, robotics/AI

Still not sold on the whole robotics at this point; still not at the level where it needs from a multi-functional capability state plus still too jerky and most are more like a CPU on wheels.

TORONTO, ON –(Marketwired — February 23, 2016) — ­­ Astro Boy may be a fictional character, but Pepper the Robot is its real-­world incarnation. Pepper –­­ the world’s first humanoid robot –­­ will join exhibitors like MasterCard, Fluid, Vizera and Eyris, as they interact with industry experts as part of The Retail Collective Lab, sponsored by MasterCard, at this year’s Dx3 Trade Show and Conference.
