The scientific staff of the University of Adelaide in South Australia upgraded the most accurate clock in the world. Thus, Sapphire Clock become an order of magnitude more accurately.
Now they can keep score in the attosecond and 10-100 times higher than counterparts in stability. This device is also often referred to as The Cryogenic Sapphire Oscillator, now it has a short-term stability of the order of 1x10-17.
In simple terms, the improved atomic clocks have an error in one second, is added or lost once in 3 million years. This result is more than 1000 times the figure ahead of all other competitors.
In the future, scientists intend to reduce Sapphire Clock size by 60%. Now atomic clocks have a height of 100 cm, and the length and width of 40 cm.
