Quantum timing, or quantum clocks, are the first technology of the second quantum revolution, relying on the discrete energy levels of electrons in atoms to generate microwave radiation of extremely precise frequency.

Evidence Quote

[44:51] Quantum timing is is is the is the the first one. Uh by which I mean quantum clocks...they rely on...the idea that uh uh electrons and atoms can't have any old energy...they have to have discrete energies...microwave radiation coming from um certain type of atom that you can measure the wavelength of very very accurately.
