From tunneling through impenetrable barriers to being in two places at the same time, the quantum world of atoms and particles is famously bizarre. Yet the strange properties of quantum mechanics are not mathematical quirks—they are real effects that have been seen in laboratories over and over.

One of the most iconic features of quantum mechanics is “entanglement”—describing particles that are mysteriously linked regardless of how far away from each other they are. Now three independent European research groups have managed to entangle not just a pair of particles, but separated clouds of thousands of atoms. They’ve also found a way to harness their technological potential.

When particles are entangled they share properties in a way that makes them dependent on each other, even when they are separated by large distances. Einstein famously called entanglement “spooky action at a distance,” as altering one particle in an entangled pair affects its twin instantaneously—no matter how far away it is.

Research appearing today in Nature Communications finds useful new information-handling potential in samples of tin(II) sulfide (SnS), a candidate “valleytronics” transistor material that might one day enable chipmakers to pack more computing power onto microchips.

The research was led by Jie Yao of the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Shuren Lin of UC Berkeley’s Department of Materials Science and Engineering and included scientists from Singapore and China. Berkeley Lab’s Molecular Foundry, a DOE Office of Science user facility, contributed to the work.

For several decades, improvements in conventional transistor materials have been sufficient to sustain Moore’s Law — the historical pattern of microchip manufacturers packing more transistors (and thus more information storage and handling capacity) into a given volume of silicon. Today, however, chipmakers are concerned that they might soon reach the fundamental limits of conventional materials. If they can’t continue to pack more transistors into smaller spaces, they worry that Moore’s Law would break down, preventing future circuits from becoming smaller and more powerful than their predecessors.

My #transhumanism work in this fun new article on future of sports:

Can bionic limbs and implanted technology make you faster and stronger? Meet biohackers working on the frontier.

Zoltan Istvan has achieved every runner’s fantasy: the ability to run without the hassle of carrying his keys. Thanks to a tiny chip implanted in his hand, Istvan doesn’t have to tie a key onto his laces, tuck it under a rock in the front yard, or find shorts with little zipper pockets built in. Just a wave of the microchip implanted in his hand will unlock the door of his home. The chip doesn’t yet negate the need for a Fitbit, a phone, or a pair of earbuds on long runs, but Istvan says it’s only a matter of time.

A long-time athlete and technology geek, Istvan identifies as a transhumanist: he believes that the transformation of the human body through ever-developing and evolving technologies will improve human life and ultimately lead to immortality.

What do you get when you mix science fiction with music and some of the most powerful and important social issues to date? You get Janelle Monáe’s highly anticipated short film (or as Monáe astutely calls it ‘Emotion Picture’) Dirty Computer, which accompanied her new album by the same name.

A futuristic celebration of queer love, black and female power, and the nonconforming individual identity!

Stealth technology may not be very stealthy in the future thanks to a US$2.7-million project by the Canadian Department of National Defence to develop a new quantum radar system. The project, led by Jonathan Baugh at the University of Waterloo’s Institute for Quantum Computing (IQC), uses the phenomenon of quantum entanglement to eliminate heavy background noise, thereby defeating stealth anti-radar technologies to detect incoming aircraft and missiles with much greater accuracy.

Ever since the development of modern camouflage during the First World War, the military forces of major powers have been in a continual arms race between more advanced sensors and more effective stealth technologies. Using composite materials, novel geometries that limit microwave reflections, and special radar-absorbing paints, modern stealth aircraft have been able to reduce their radar profiles to that of a small bird – if they can be seen at all.

News Brief: Researchers have created a miniaturized device that can transform electronic signals into optical signals with low signal loss. They say the electro-optic modulator could make it easier to merge electronic and photonic circuitry on a single chip. The hybrid technology behind the modulator, known as plasmonics, promises to rev up data processing speeds. “As with earlier advances in information technology, this can dramatically impact the way we live,” Larry Dalton, a chemistry professor emeritus at the University of Washington, said in a news release. Dalton is part of the team that reported the advance today in the journal Nature.

A new microchip technology capable of optically transferring data could solve a severe bottleneck in current devices by speeding data transfer and reducing energy consumption by orders of magnitude, according to an article published in the April 19, 2018 issue of Nature.

Researchers from Boston University, Massachusetts Institute of Technology, the University of California Berkeley and University of Colorado Boulder have developed a method to fabricate silicon chips that can communicate with light and are no more expensive than current technology. The result is the culmination of a several-year-long project funded by the Defense Advanced Research Project Agency that was a close collaboration between teams led by Associate Professor Vladimir Stojanovic of UC Berkeley, Professor Rajeev Ram of MIT, and Assistant Professor Milos Popovic from Boston University and previously CU Boulder. They collaborated with a semiconductor research team at the Colleges of Nanoscale Science and Engineering (CNSE) of the State University of New York at Albany.

The electrical signaling bottleneck between current microelectronic chips has left light communication as one of the only options left for further technological progress. The traditional method of data transfer-electrical wires-has a limit on how fast and how far it can transfer data. It also uses a lot of power and generates heat. With the relentless demand for higher performance and lower power in electronics, these limits have been reached. But with this new development, that bottleneck can be solved.
