A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber ...

Kyoto-based precision equipment manufacturer Shimadzu Corporation has begun selling the world's most accurate commercially available timepiece -- a strontium optical lattice clock with a deviation of ...

USTC researchers created a long-lived Schrödinger-cat state, boosting quantum metrology and precision measurements. Their ...

The invention – called the optical lattice clock – is a thousand times more accurate than cesium atomic clocks used for international timekeeping and is a contender for redefining how long a ...

In recent years, physicists have been trying to better understand the behavior of individual quantum particles as they move in space. Yet directly imaging these particles with high precision has so ...

Japanese precision equipment maker Shimadzu Corp said Wednesday that it has begun selling an optical lattice clock with a deviation of less than one second over 10 billion years, making it the most ...

The strontium optical lattice clock is the first of its kind to be commercially available and will cost about 500 million yen ($3.3 million).

There is a clock called the "optical lattice clock." First, each atom cooled by laser is captured in a 3-D micro space (optical lattice), which is created by interference of laser beams with special ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

The world's most accurate clock – so precise that it would take 10 billion years for it to deviate by one second – has gone on sale for $3.3 million in Japan. | TAG24 ...
