Glad folks realizes and admit to the risks; however, I stand by my argument until the underpinning technology is still tied to dated digital technology; it will be hacked by folks like China who are planning to be on a new Quantum network and platforms. Reason why all countries must never lose sight of replacing their infrastructure and the net with Quantum technology.

A team of researchers from Pittsburgh has won DARPA’s Cyber Grand Challenge – a competition billed as the ‘world’s first automated network defense tournament.’ The implications for the Internet of Things (IoT) are grave, as the machines on display threaten to ravage the already flaky state of IoT security.

DARPA, the Department of Defense’s (DoD) Defense Advanced Research Projects Agency, is a wing of the US military that investigates how the latest technological breakthroughs can be put to use on the battlefield. With nation-state cybersecurity now declared a new front in conventional warfare, militaries around the world will be flocking to gather the tools needed to exert force in this new medium.

So while the DARPA competition presents itself as a smiley affair, it dies represent the new face of an emerging weapon – and the most promising weapon on display came from the aforementioned ForAllSecure, a startup with close ties to Pittsburgh’s Carnegie Mellon University.

I already voiced my concerns of this technology in the hands of criminals and terrorists. If we can have it so can others. Only when QC and a Quantum net is in place will we be truly protected with bots.

Cybersecurity could soon be another place where bots become invaluable for experts. DARPA recently organized The Cyber Grand Challenge, where computer algorithms showed how easy it is to clean up vulnerabilities in code written by humans. ( DARPA )

The Cyber Grand Challenge took place under DARPA patronage, and it is good to see how preoccupied the U.S. Department of Defense is with cybersecurity.

The event pitted computers against each other in an attempt to uncover which one can best fulfill the tasks of human cybersecurity researchers, that is, discovering a bug in a software program and fixing it.

I will like to see how this stacks against China’s Quantum net, QC platform, AI, and hackers in the future. Not sold at this point until we truly have a QC infrastructure in place.

At DARPA’s Cyber Grand Challenge, bots showed off their ability to help a world wallowing in vulnerable code.

LAS VEGAS, Nev. — Mayhem ruled the day when seven AIs clashed here last week — a bot named Mayhem that, along with its competitors, proved that machines can now quickly find many types of security vulnerabilities hiding in vast amounts of code.

Sponsored by the Defense Advanced Research Projects Agency, or DARPA, the first-of-its-kind contest sought to explore how artificial intelligence and automation might help find security and design flaws that bad actors use to penetrate computer networks and steal data.

Dmitry Fedyanin from the Moscow Institute of Physics and Technology and Mario Agio from the University of Siegen and LENS have predicted that artificial defects in the crystal lattice of diamond can be turned into ultrabright and extremely efficient electrically driven quantum emitters. Their work, published in New Journal of Physics, demonstrates the potential for a number of technological breakthroughs, including the development of quantum computers and secure communication lines that operate at room temperature.

The research conducted by Dmitry Fedyanin and Mario Agio is focused on the development of electrically driven single-photon sources—devices that emit when an electrical current is applied. In other words, using such devices, one can generate a photon “on demand” by simply applying a small voltage across the devices. The probability of an output of zero photons is vanishingly low and generation of two or more photons simultaneously is fundamentally impossible.

Until recently, it was thought that quantum dots (nanoscale semiconductor particles) are the most promising candidates for true single-photon sources. However, they operate only at very low temperatures, which is their main drawback – mass application would not be possible if a device has to be cooled with liquid nitrogen or even colder liquid helium, or using refrigeration units, which are even more expensive and power-hungry. At the same time, certain point defects in the crystal lattice of diamond, which occur when foreign atoms (such as silicon or nitrogen) enter the diamond accidentally or through targeted implantation, can efficiently emit single photons at room temperature. However, this has only been achieved by optical excitation of these defects using external high-power lasers. This method is ideal for research in scientific laboratories, but it is very inefficient in practical devices.

Quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can. Instead of the bits of classical computation, which can represent 0 or 1, quantum computers consist of quantum bits, or qubits, which can, in some sense, represent 0 and 1 simultaneously.

Although quantum systems with as many as 12 have been demonstrated in the lab, building quantum computers complex enough to perform useful computations will require miniaturizing qubit technology, much the way the miniaturization of transistors enabled modern computers.

Trapped ions are probably the most widely studied qubit technology, but they’ve historically required a large and complex hardware apparatus. In today’s Nature Nanotechnology, researchers from MIT and MIT Lincoln Laboratory report an important step toward practical quantum computers, with a paper describing a prototype chip that can trap ions in an electric field and, with built-in optics, direct toward each of them.

Not so long ago we had to assume that we’ll never be able to travel faster than light. This was based on scientists’ sensible belief that we can travel through space but cannot change the nature of space itself. Then the idea of ‘Warp Drive’ came along to challenge and seemingly change all of the barriers that Einstein’s theory identified. Warp Drive is all about squashing and stretching space — a pretty ambitious task to begin with. So maybe it’s time again to have a look at how far we’ve already come or how close we are to seeing a real warp drive built by humans.

In May 1994, theoretical physicist Miguel Alcubierre finally presented his proposal of “The Warp Drive: Hyper-fast travel within general relativity” in a scientific journal called Classical and Quantum Gravity.

He indeed was inspired by Star Trek and its creator Gene Roddenberry, who famously coined the expression “Warp Drive” to explain the inexplicable propulsion of the Starship Enterprise as prodigious speed was just necessary to enable his fictional space travelers to leap from star to star on their trek.

In a development that could greatly help the study of quantum phenomena, scientists have created a theoretical model for a new form of light that combines the properties of photons and electrons. If turned into reality, the new light form could also be used to make electrical circuits which at present use electrons for conduction.

Scientists from Imperial College London published a study in the journal Nature Communications on Friday that shows “it is possible to create a new form of light by binding light to a single electron, combining the properties of both,” according to a statement issued by the college.

Light, which is made up of photons, usually interacts with a large number of electrons on the surface of whatever material it comes in contact with. For the study, researchers from Imperial used “a recently discovered class of materials known as topological inhibitors.” Combining that with “theoretical physics to model the behavior of light,” they found that light could interact with only one electron on the surface.
