A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists ...
What if time doesn't actually exist until something changes? Scientists at the University of Birmingham created a tiny "mini ...
How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...
Microsoft co-founder Bill Gates recently surprised the industry by bringing Nvidia CEO Jensen Huang’s stated timeline for quantum computing forward by almost a decade, saying that its phenomenal ...

Quantum breakthrough reveals ultra‑stable clocks for deep‑space navigation
How does a clock become precise enough to guide a spacecraft across interstellar distance without drifting a single second over millions of years? Recent advances in quantum physics are pushing ...
As Make puts it, the atomic clock is old and busted. The quantum-logic clock from National Institute of Standards and Technology, keeping time 100,000 times more accurately than its predecessor, is ...
Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...
Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...
The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
