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.”

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.

IARPA Project Targets Hidden Algorithms of the Brain

Posted by in categories: computing, information science, neuroscience, robotics/AI

Whether in the brain or in code, neural networks are shaping up to be one of the most critical areas of research in both neuroscience and computer science. An increasing amount of attention, funding, and development has been pushed toward technologies that mimic the brain in both hardware and software to create more efficient, high performance systems capable of advanced, fast learning.

One aspect of all the efforts toward more scalable, efficient, and practical neural networks and deep learning frameworks we have been tracking here at The Next Platform is how such systems might be implemented in research and enterprise over the next ten years. One of the missing elements, at least based on the conversations that make their way into various pieces here, for such eventual end users is reducing the complexity of the training process for neural networks to make them more practically useful–and without all of the computational overhead and specialized systems training requires now. Crucial then, is a whittling down of how neural networks are trained and implemented. And not surprisingly, the key answers lie in the brain, and specifically, functions in the brain and how it “trains” its own network that are still not completely understood, even by top neuroscientists.

In many senses, neural networks, cognitive hardware and software, and advances in new chip architectures are shaping up to be the next important platform. But there are still some fundamental gaps in knowledge about our own brains versus what has been developed in software to mimic them that are holding research at bay. Accordingly, the Intelligence Advanced Research Projects Activity (IARPA) in the U.S. is getting behind an effort spearheaded by Tai Sing Lee, a computer science professor at Carnegie Mellon University’s Center for the Neural Basis of Cognition, and researchers at Johns Hopkins University, among others, to make new connections between the brain’s neural function and how those same processes might map to neural networks and other computational frameworks. The project called the Machine Intelligence from Cortical Networks (MICRONS).

No Big Bang? Quantum equation predicts universe has no beginning

Posted by in categories: cosmology, information science, mathematics, quantum physics, singularity

New equation proves no “Big Bang” theory and no beginning either as well as no singularity.


(Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein’s theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.

The widely accepted age of the , as estimated by , is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or . Only after this point began to expand in a “Big Bang” did the universe officially begin.

General Relativity Might Be No Match for a Five-Dimensional Black Hole

Posted by in categories: cosmology, information science, physics, singularity

We don’t live in a world that’s pinning the survival of humanity of Matthew McConaughey’s shoulders, but if it turns out the plot of the 2014 film Interstellar is true, then we live in a world with at least five dimensions. And that would mean that a ring-shaped black hole would, as scientists recently demonstrated, “break down” Einstein’s general theory of relativity. (And to think, the man was just coming off a phenomenal week.)

In a study published in Physical Review Letters, researchers from the UK simulated a black hole in a “5-D” universe shaped like a thin ring (which were first posited by theoretical physicists in 2002). In this universe, the black hole would bulge strangely, with stringy connections that become thinner as time passes. Eventually, those strings pinch off like budding bacteria or water drops off a stream and form miniature black holes of their own.

This is wicked weird stuff, but we haven’t even touched on the most bizarre part. A black hole like this leads to what physicists call a “naked singularity,” where the equations that support general relativity — a foundational block of modern physics — stop making sense.

Amoeba-inspired computing system outperforms conventional optimization methods

Posted by in categories: computing, information science, nanotechnology

(Phys.org)—Researchers have designed and implemented an algorithm that solves computing problems using a strategy inspired by the way that an amoeba branches out to obtain resources. The new algorithm, called AmoebaSAT, can solve the satisfiability (SAT) problem—a difficult optimization problem with many practical applications—using orders of magnitude fewer steps than the number of steps required by one of the fastest conventional algorithms.

The researchers predict that the amoeba-inspired may offer several benefits, such as high efficiency, miniaturization, and low , that could lead to a new computing paradigm for nanoscale high-speed .

Led by Masashi Aono, Associate Principal Investigator at the Earth-Life Science Institute, Tokyo Institute of Technology, and at PRESTO, Japan Science and Technology Agency, the researchers have published a paper on the amoeba-inspired system in a recent issue of Nanotechnology.

This New Artificial Intelligence Script-Reading Program Could Find Your Next Oscar Role (Exclusive)

Posted by in categories: entertainment, information science, robotics/AI

Actors and Actresses will never have to worry about reading through pages of scripts to decide whether or not the role is worth their time; AI will do the work for you.


A version of this story first appeared in the Feb. 26 issue of The Hollywood Reporter magazine. To receive the magazine, click here to subscribe.

During his 12 years in UTA’s story department, Scott Foster estimates he read about 5,500 screenplays. “Even if it was the worst script ever, I had to read it cover to cover,” he says. So when Foster left the agency in 2013, he teamed with Portland, Ore.-based techie Brian Austin to create ScriptHop, an artificial intelligence system that manages the volume of screenplays that every agency and studio houses. “When I took over [at UTA], we were managing hundreds of thousands of scripts on a Word document,” says Foster, who also worked at Endeavor and Handprint before UTA. “The program began to eat itself and become corrupt because there was too much information to handle.” ScriptHop can read a script and do a complete character breakdown in four seconds, versus the roughly four man hours required of a reader. The tool, which launches Feb. 16 is free, and is a sample of the overall platform coming later in 2016 that will recommend screenplays as well as store and manage a company’s library for a subscription fee of $29.99 a month per user.

Brain scan for artificial intelligence shows how software thinks

Posted by in categories: biotech/medical, computing, information science, robotics/AI

Neural networks have become enormously successful – but we often don’t know how or why they work. Now, computer scientists are starting to peer inside their artificial minds.

A PENNY for ’em? Knowing what someone is thinking is crucial for understanding their behaviour. It’s the same with artificial intelligences. A new technique for taking snapshots of neural networks as they crunch through a problem will help us fathom how they work, leading to AIs that work better – and are more trustworthy.

In the last few years, deep-learning algorithms built on neural networks – multiple layers of interconnected artificial neurons – have driven breakthroughs in many areas of artificial intelligence, including natural language processing, image recognition, medical diagnoses and beating a professional human player at the game Go.
