There're problems with increasing atom number. It is true that more atoms will allow one to resolve QPN easier, more atoms make clock rotations (along the Bloch sphere) much harder, as for a spin-squeezed clock doing Ramsey sequence, you need at least two pi/2 rotations to rotate the squeezed state.
- dekhn 5y agoStupid question: what you're describing looks very similar to NMR (using RF to shape ensembles of magnetic spins, often shifting them around the bloch sphere).
- Xpol 5y agoYou're right, the techniques in NMR like Rabi and Ramsey spectroscopy, spin echoes are all used in atomic clock experiments too.
