Neglected atom has top properties for atomic clocks

 

Like watchmakers choosing superior materials to build a fine timepiece, CQT physicists have singled out an atom that could allow us to build better atomic clocks. The team report on the potential of the element lutetium in Nature Communications. “The ultimate performance of a clock comes down to the properties of the atom – how insensitive the atom is to its environment. I would call lutetium top in its class,” says CQT Principal Investigator Murray Barrett.

Design innovations smash a record for photon source brightness

CQT researchers have broken a record for the brightness of an entangled photon pair source, thanks to design improvements reported in Optics Express. In the process, they discovered that scientists have for decades been making such devices more complicated than they needed to be.

Highly excited atoms show promise for quantum networks

Future quantum networks may need a technology demonstrated in a laboratory at CQT: a way to use Rydberg atoms to convert microwave signals into optical signals. The work, by the experimental group of CQT’s Wenhui Li with theorists Martin Kiffner and Dieter Jaksch, is described in a paper published in March in Physical Review Letters.
