It would take 15 billion years for the clock that occupies Jun Ye’s basement lab at the University of Colorado to lose a second. This undated handout photo obtained September 8, 2021 shows ...

A greatly simplified block diagram of an atomic frequency standard (also called an atomic clock) is shown in Figure 2.1. This consists of an atomic resonator, a local oscillator, and additional ...

Markus Lutz is CTO and Founder of SiTime Corporation. He is a MEMS expert, a prolific entrepreneur and inventor who holds over 100 patents. Timekeeping might be the unsung hero of human ingenuity. The ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

From freeze-dried strawberries to memory foam and scratch-resistant glasses, space exploration is the force behind a myriad of life-changing innovations. Now it’s time for a terrestrial innovation to ...

Atomic clocks are based upon quartz crystals. These crystals vibrate at a very uniform rate when an electric current is passed through them. By measuring minute variations in those vibrations over ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Time crystals are an oddity of quantum physics, but new calculations show that these bizarre materials could be useful for building very accurate clocks. All crystals are defined by repetition – ...

It would take 15 billion years for the clock that occupies Jun Ye's basement lab at the University of Colorado to lose a second—about how long the universe has existed. For this invention, the Chinese ...
