GPS is vital to modern navigation, but it's extremely fragile. Never mind coverage -- if a satellite fails or there's a jamming attack, it quickly becomes useless. Scientists may have a much more robust answer, though. Scientists have demonstrated...
Quantum ‘compass’ promises navigation without using GPS
GPS is vital to modern navigation, but it's extremely fragile. Never mind coverage -- if a satellite fails or there's a jamming attack, it quickly becomes useless. Scientists may have a much more robust answer, though. Scientists have demonstrated...
If you're going to create virtually unbreakable quantum networks, you need to create quantum entanglement so that particles, and thus pieces of data, are intertwined at long distances. There hasn't been a reliable way to make that happen, however, u...
There's a worldwide race to dominate quantum computing, and two new pieces of legislation might help the US claim the lead. Senator Kamala Harris has introduced the first, the Quantum Computing Research Act, to provide a "competitive edge" in develo...
It's hard to study quantum behavior on Earth. You can amplify the effects of quantum mechanics by zapping groups of specific atoms (Bose-Einstein condensates) with lasers that drop their temperature to near absolute zero, but that only works for frac...
How do you find out what happens to physics near absolute zero (aka 0 kelvin), the temperature where particle motion virtually stops? Scientists at the University of Basel might have just the device to do it. They've developed a nanoelectronics chi...
Researchers have pushed the precision and stability of atomic clocks to increasingly greater levels over the last few years. A big advancement was the introduction of optical lattices, lasers which essentially quarantine individual atoms and boost ac...
One of the greatest challenges in quantum computing is... well, making the computers. You may need exotic manufacturing techniques just to handle the very exacting requirements, such as positioning the atoms in quantum bits in exact positions at clo...
Hashtags could soon be useful for a lot more than fostering discussion on your favorite social network. Researchers have developed a hashtag-shaped quantum chip (shown below) that could confirm the existence of the oddball Majorana particle, which ex...
Scientists from Lancaster University have developed a foolproof anti-counterfeiting measure using a combination of quantum physics and smartphone technology. Previously, the team created unique atomic-scale IDs based on irregularities found in 2D mat...
