The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

Add Yahoo as a preferred source to see more of our stories on Google. For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

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 ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

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 ...

However, compared to a quantum clock, atomic clocks are as accurate as a one-dollar antique pocket watch that's been whacked several times with a coal hammer. By measuring how atoms jump between ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

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 ...

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 ...
