Two or one splashing? It's different

If two children splash in the sea high water waves will emerge due to constructive superposition. Different observations are made for the microscopic world in an experiment at the University of Bonn, where physicists used ...

Atoms queue up for quantum computer networks

In order to develop future quantum computer networks, it is necessary to hold a known number of atoms and read them without them disappearing. To do this, researchers from the Niels Bohr Institute have developed a method ...

NIST launches a new US time standard: NIST-F2 atomic clock

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has officially launched a new atomic clock, called NIST-F2, to serve as a new U.S. civilian time and frequency standard, along with the ...

A rock is a clock: Physicists use matter to measure time

What is the simplest, most fundamental clock? Physicist Holger Müller and his UC Berkeley colleagues have shown that a single atom is sufficient to measure time using its high-frequency matter wave. Conversely, the frequency ...

Physicists split an atom using quantum mechanics precision

Researchers from the University of Bonn have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum ...
