Summary

Story summary

The quantum clock built with a double quantum dot (DQD) requires energy to measure its ticks up to a billion times greater than energy used to operate it.
The findings were published in Physical Review Letters.
The results show that observation plays a crucial role in quantum timekeeping.
The study proposes time may emerge from information extraction.
This finding could influence future quantum-device design.
