The tick-tock of the optical clock

(PhysOrg.com) -- UK's National Physical Laboratory time scientists have made an accurate measurement of the highly forbidden octupole transition frequency in an ytterbium ion, which could be used as the basis for the next ...

Physicists make leaps in reading out qubits with laser light

Qubits are a basic building block for quantum computers, but they're also notoriously fragile—tricky to observe without erasing their information in the process. Now, new research from the University of Colorado Boulder ...

Seeing through walls of unknown materials

Researchers at Duke University have devised a way to see through walls using a narrow band of microwave frequencies without any advance knowledge of what the walls are made out of. Besides having obvious applications in the ...
