We propose a method for laser cooling group-II-like atoms without changingthe quantum state of their nuclear spins, thus preserving coherences that areusually destroyed by optical pumping. As group-II-like atoms have a $^1S_0$closed-shell ground state, nuclear spin and electronic degrees of freedom aredecoupled, allowing for independent manipulation. The hyperfine interactionthat couples these degrees of freedom in excited states can be suppressedthrough the application of external magnetic fields. Our protocol employsresolved-sideband cooling on the forbidden clock transition, $^1S_0 \to{}^3P_0$, with quenching via coupling to the rapidly decaying $^1P_1$ state,deep in the Paschen-Back regime. This makes it possible to laser cool neutralatomic qubits without destroying the quantum information stored in theirnuclear spins, as shown in two examples, $^{171}$Yb and $^{87}$Sr.Comment: 4 pages, 3 figures v4: minor changes in text, changes in the  references, published versio
