UCLA-led team develops new approach to building quantum computers

Stephan Sullivan An artist’s representation shows the researchers’ quantum functional groups (bright colored spheres) linked to larger molecules. Main takeaways: Stronger, faster. Quantum computers promise far greater speed and processing power than today’s most advanced supercomputers Quantum quantum. As these next-generation computers relied on the interaction of fragile atomic and subatomic particles, increasing their processing power proved to be a challenge. A chemical solution. Researchers have created a new molecule that has the potential to protect quantum interactions on a larger scale without the need for traditional electrical engineering tools and machines. Quantum computing, although still in its infancy, has the potential to dramatically increase processing power by exploiting the odd behavior of particles at the smallest scales. Several research groups have reported performing calculations that would take thousands of years for traditional supercompu...

A Minimalist Approach to the Hunt for Dark Matter

Specifically, the Antipas team used their experiments to search for a class of dark matter known as ultralight dark matter. At their heaviest, ultra-bright dark matter particles are still about a trillion times lighter than electrons. According to quantum mechanics, all matter has both particle-like and wave-like qualities, with larger objects typically having more particle-like qualities and smaller ones having more wave-like qualities. “When people talk about ultra-bright dark matter, they mean that dark matter is more like a wave,” said physicist Kathryn Zurek of the California Institute of Technology, who was not involved in the experiment. Like all other dark matter experiments so far, the Antipas search has found nothing. However, the absence of their discovery helps limit the properties of dark matter, as experiments show what dark matter is not. Also, the team’s approach differs from that of the more famous dark matter experiment, which looks for particles...

A massive asteroid the size of BUS will make a very close approach to Earth today – and astronomers only detected it three DAYS ago The asteroid, called 2022 NF, is between 5.4 and 12 meters in diameter It will come within 54,843.9 miles of our planet at approximately 2:45 p.m. BST Experts only found the asteroid on July 4th using a telescope in Hawaii By Shivali Best For Mailonline Published: 05:38 EDT, 7 July 2022 | Updated: 05:39 EDT, 7 July 2022 An asteroid the size of the London bus will make a very close approach to Earth today, although it was only detected a few days ago. The asteroid, called 2022 NF, will be within 54,843.9 miles of our planet at approximately 2:45 p.m. BST, according to NASA. To put it in perspective, that’s just over a quarter of the distance from the Moon at its closest point to Earth, which is 225,623 miles away. Fortunately, NASA’s calculations suggest that the massive space r...
