A Game Changer in Quantum Computing:
The ingredients for superfast computers could be nearly in place. For the first time, researchers have demonstrated that two silicon transistors acting as quantum bits can perform a tiny calculation.

The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers, which harness the science of the very small — the strange behaviour of subatomic particles — to solve computing challenges that are beyond the reach of even today’s fastest supercomputers. Potentially transforming fields like encryption and the search for new pharmaceuticals.

The significant advance, by a team at the University of New South Wales (UNSW) in Sydney appears today in the international journal Nature (“A two-qubit logic gate in silicon”).


“What we have is a game changer,” said team leader Andrew Dzurak, Scientia Professor and Director of the Australian National Fabrication Facility at UNSW.

“We’ve demonstrated a two-qubit logic gate — the central building block of a quantum computer — and, significantly, done it in silicon. Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs, which rely on more exotic technologies.

“This makes the building of a quantum computer much more feasible, since it is based on the same manufacturing technology as today’s computer industry,” he added.

My new and first article for The Daily Dot. It’s about transhumanism and the Immortality Bus tour:


BY ZOLTAN ISTVAN

Even though I was born after the 1960s, I’ve always been fascinated with that era. Some people credit Ken Kesey’s cross country bus trip aboard colorfully painted “Further” as helping to create a generation of hippies. Of course, my Immortality Bus (shaped to look like a coffin) wants to stir up the national consciousness as well, aiming to usher in its own cultural shift. Whereas the ‘60s were about peace, love, drugs, and sex, I believe the next decade will be about virtual reality, implants, transhumanism, and overcoming death with science. For futurists like myself, that’s quite an intoxicating mix.

The fact is that a lot of radical tech, science, and medicine are already here in America. Consider that today the paralyzed can walk via exoskeleton suits, the blind can see via bionic eyes, and the limbless can grab a bottle of water and drink with artificial limbs that connect to their nervous system. Additionally, lifespans are increasing for people all around the planet. Science is rapidly making the world a better place, and it’s starting to eliminate suffering and hardship for billions of people.

First it was toggle switches. And then keyboards, the mouse and other standard interface devices gave us control of computers and the digital world. From the tangible, to hands-free and beyond, the ways in which we control digital systems are expanding. We’ve collected just a few of the interesting products and concepts that are breaching the two-dimensional world of computing and merging it with our physical reality.

The heat-death of the universe need not bring an end to the computing age. A strange device known as a time crystal can theoretically continue to work as a computer even after the universe cools. A new blueprint for such a time crystal brings its construction a step closer.

Ordinary crystals are three-dimensional objects whose atoms are arranged in regular, repeating patterns – just like table salt. They adopt this structure because it uses the lowest amount of energy possible to maintain.

Earlier this year, Frank Wilczek, a theoretical physicist at the Massachusetts Institute of Technology, speculated that a similar structure might repeat regularly in the fourth dimension – time.

On the cusp of a far-reaching revolution thanks to the advances in artificial intelligence and computing, it’s easy to feel a bit…concerned. Well, maybe more than just a bit, especially if you consider societal attitudes about technology.

Truth is that the way we perceive the world around us is conditioned to a degree by the environment we grow up within. There’s also little doubt that certain cultures are more open and adaptive to technology than others. But one could argue that the potential enhancements that AI could usher in are so dramatically advanced that even the earliest adopters within Silicon Valley aren’t really prepared for what’s coming.

So it’s safe to ask, before this great wave of artificial intelligence arrives and we become fully integrated with it, shouldn’t we strive to change our inherited mental models and let go of antiquated thinking patterns?

Sign language has helped the hearing-impaired communicate for many centuries, way before it was formalised and officially recognised, but this long-standing language of gestures has now been given a 21st-century technological upgrade. Saudi designer and media artist Hadeel Ayoub has invented a smart glove that recognises hand movements and converts them into the relevant text.

Much like Google Translate can give anyone a basic grasp of a foreign language in an instant, this glove is designed to help sign language users make themselves understood by those who can’t usually interpret it.

Five flex sensors sit on the fingers, monitoring how they’re being manipulated, while an accelerometer integrated into the fabric of the glove figures out how the hand is being held and the direction in which it’s pointing. Through three successive prototypes, the glove has been made thinner, lighter, and faster, and the latest version includes a text-to-speech chip to vocalise the words as they’re signed.

IBM Research has announced a “major engineering breakthrough” that could lead to carbon nanotubes replacing silicon transistors in future computing technologies.

A few weeks ago, a drunk man in Japan was arrested for kicking a humanoid robot that was stationed as a greeter at a SoftBank, Corp., store, which develops the robots. According to the police report, the man said he was angry at the attitude of one of the store clerks. The “Pepper robot” now moves more slowly, and its internal computer system may have been damaged.

Under current Japanese law, the man can be charged with damage to property, but not injury, since injury is a charge reserved for humans. Dr. Yueh-Hsuan Weng, who is cofounder of the ROBOLAW.ASIA Initiative at Peking University in China, and former researcher of the Humanoid Robotics Institute at Waseda University in Japan, thinks a better charge lies somewhere in between.

Weng is advocating for special robot laws to address the unique nature of human-robot interactions. He argues that humans perceive highly intelligent, social robots like Pepper (which can read human emotions) differently than normal machines—maybe more like pets—and so the inappropriate treatment of robots by humans should be handled with this in mind.
