Tinier and less power-hungry quantum atomic clock push toward intelligent IoT

Scientists have developed an ultra-low-power atomic clock (ULPAC) for small satellites to enable future communication systems beyond 5G. The proposed device outperforms the current industry standards in various benchmarks, such as size, stability, and power consumption.
