Quantum computers finally seem to be coming of age with promises of “quantum supremacy” by the end of the year. But there’s a problem—very few people know how to work them.

The bold claim of achieving “quantum supremacy” came on the back of Google unveiling a new quantum chip design. The hyperbolic phrase essentially means building a quantum device that can perform a calculation impossible for any conventional computer.

In theory, quantum computers can crush conventional ones at important tasks like factoring large numbers. That’s because unlike normal computers, whose bits can either be represented as 0 or 1, a quantum bit—or “qubit”—can be simultaneously 0 and 1 thanks to a phenomenon known as superposition.

  • The UN will be using the blockchain Ethereum to distribute funds from the World Food Program to more than 10,000 people in Jordan this summer.
  • The computer network is making humanitarian giving simpler and more secure than ever.

Technology has the power to improve people’s lives — and not just by supplying flying cars to millionaires. The computer networks that brought us Bitcoins are advancing in ways that will make humanitarian giving simpler and more secure than ever.

Each year, the world’s greatest innovators and inventors gather for the Edison Awards to celebrate “game-changing” developments in technology, engineering, marketing, and design. Here are just some of the innovations that are already transforming our world.

Each year, innovators from across the globe trade in their lab coats and laptops for ties and gowns to honor the nominees at the Edison Awards ceremony in New York City. Over the past three decades, the awards have highlighted the most innovative products and people in science. Last year’s honorees featured Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto.

NASA just announced several bounties to improve its FUN3D software, which is used to simulate fluid dynamics. The system is used internally at NASA, as well as by companies like Boeing and Lockheed, to develop and optimize new vehicles and engines.

The FUN3D project was started back in the 1980s, and it has been in active development for decades, but NASA’s looking for help to optimize the code. It’s offering $15,000 and $10,000 prizes to the top two contributors of code optimizations, and is also offering another bounty for more general optimization suggestions.

For decades, scientists have tracked hints of a thread-like structure that ties together galaxies across the universe. Theories, computer models, and indirect observations have indicated that there is a cosmic web of dark matter that connects galaxies and constitutes the large-scale structure of the cosmos. But while the filaments that make up this web are massive, dark matter is incredibly difficult to observe.

Now, researchers have produced what they say is the first composite image of a dark matter filament that connects galaxies together.

“This image moves us beyond predictions to something we can see and measure,” said Mike Hudson, a professor of astronomy at the University of Waterloo in Canada, co-author of a new study published in the Monthly Notices of the Royal Astronomical Society.

Physicists at the University of California, Irvine and elsewhere have fabricated new two-dimensional quantum materials with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics.

In three separate studies appearing this month in Nature, Science Advances and Nature Materials, UCI researchers and colleagues from UC Berkeley, Lawrence Berkeley National Laboratory, Princeton University, Fudan University and the University of Maryland explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.

The common threads running through the papers are that the research is conducted at extremely cold temperatures and that the signal carriers in all three studies are not electrons — as with traditional silicon-based technologies — but Dirac or Majorana fermions, particles without mass that move at nearly the speed of light.
