In qubit phase tracking, does the phase $\delta$ have to be synchronized to the Larmor precession?
In many textbooks (e.g. LaPierre 2021 or Byrd 2022), when dealing with the physical implementation of quantum gates in spin qubits, Larmor precession is usually introduced first as a way to rotate the ...
