New super-accurate optical atomic clocks pass critical test

Researchers have measured an optical clock's ticking with record-breaking accuracy while also showing the clock can be operated with unprecedented consistency. These achievements represent a significant step toward demonstrating ...

Physics: Not everything is where it seems to be

Scientists at TU Wien, the University of Innsbruck and the ÖAW have for the first time demonstrated a wave effect that can lead to measurement errors in the optical position estimation of objects. The work now published ...

More reliable way to produce single photons

Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.

NASA completes Webb Telescope Center of Curvature pre-test

Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb's fully assembled primary mirror, called a Center of Curvature test.

Breakthrough in sensing at the nanoscale

Researchers have made a breakthrough discovery in identifying the world's most sensitive nanoparticle and measuring it from a distance using light. These super-bright, photostable and background-free nanocrystals enable a ...

Atomic clock precision could soon be used at home and work

A new development in fibre optic technology could soon bring atomic clock precision to any home or business with a fibre connection, according to researchers at The University of Western Australia and the University of Adelaide.
