This environmentally friendly quantum sensor runs on sunlight
Quantum tech is going green. A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces…
Quantum entanglement makes quantum communication even more secure
Stealthy communication just got more secure, thanks to quantum entanglement. Quantum physics provides a way to share secret information that’s mathematically proven to be safe from the prying eyes of…
Aliens could send quantum messages to Earth, calculations suggest
An intelligent alien civilization could beam quantum messages to Earth. Particles of light, or photons, could be transmitted over vast, interstellar distances without losing their quantum nature, researchers report June…
Quantum physics exponentially improves some types of machine learning
Machine learning can get a boost from quantum physics. On certain types of machine learning tasks, quantum computers have an exponential advantage over standard computation, scientists report in the June…
A new gravity sensor used atoms’ weird quantum behavior to peer underground
The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those…
‘From Data to Quanta’ defends Niels Bohr’s view of quantum mechanics
From Data to QuantaSlobodan PerovićUniv. of Chicago, $45 Ever since Max Planck introduced the idea of the quantum to the world, physicists have argued about whether reality is more like…
The quantum ‘boomerang’ effect has been seen for the first time
Some quantum particles gotta get right back to where they started from. Physicists have confirmed a theoretically predicted phenomenon called the quantum boomerang effect. An experiment reveals that, after being…
Quantum particles can feel the influence of gravitational fields they never touch
If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields…
A century of quantum mechanics questions the fundamental nature of reality
Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality. And in the century just past, scientists have dug deep enough to discover that reality’s…
