Trapped ions have previously only been entangled in one and the same laboratory. Now, teams led by Tracy Northup and Ben Lanyon from the University of Innsbruck have entangled two ions over a distance of 230 meters.
Microresonators based frequency combs, microcombs, have attracted huge interest in the last decades for their revolutionary performance of compact size, flexible comb spacing, and broad bandwidth. Wide applications of microcombs ...
A team of researchers has developed the first chip-scale titanium-doped sapphire laser—a breakthrough with applications ranging from atomic clocks to quantum computing and spectroscopic sensors.
Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar—the superdense, ...
Top scientists and security experts moved the "Doomsday Clock" forward on Tuesday to just 90 seconds to midnight -– signaling an increased risk to humanity's survival from the nuclear shadow over the Ukraine conflict and ...
The "Doomsday Clock," which represents the judgment of leading science and security experts about the perils to human existence, is to be updated on Tuesday against the backdrop of the war in Ukraine and other crises.
Tick, tick, tick. An update is coming to the "Doomsday Clock," representing the judgment of leading science and security experts about the perils to human existence.
As technologies keep advancing at exponential rates and demand for new devices rises accordingly, miniaturizing systems into chips has become increasingly important. Microelectronics has changed the way we manipulate electricity, ...
What if there were a gadget that could within short order check whether you have COVID or the flu—or maybe it would even pick up that you have diabetes without knowing it? The device could figure all this out without you ...
Atomic clocks are crucial for everyday living as they help our telecommunications, electrical power grids, GPS systems, transportation, and other processes around the world keep precise time. Some of these clocks use lasers ...
