tune couplings between fine-structure states [@spinlattice1; @spinlattice2], which can lead to large heating and decoherence from spontaneous emissions in the case of alkali atoms. In addition, spin-dependent lattices made in this way can be easily generated so that motion of the two potentials is independent in 2D. Below we discuss this implementation in detail, developing a complete proposal for quantum computing with alkaline-earth(-like) atoms, including methods for production of a quantum register and for performing single-qubit operations. Qubit readout with individual addressing can be performed in a similar manner to the case of electronic-state-dependent lattices [@aeshort], using magnetic gradient fields to shift the energy of states in the $^3$P$_2$ manifold. In nuclear-spin-dependent lattices, the large two-body loss rates from metastable $^3$P$_2$ levels can also be used to perform two-qubit gate via a lossy blockade mechanism as an alternative to the implementation of gates via controlled collisions [@spinlattice1]. This was originally discussed for electron-state-dependent lattices [@aeshort], and we provide further details of this mechanism below.

This alternative scheme with nuclear-spin-dependent lattices has the advantage of not requiring additional lasers to trap the $^1$S$_0$ and $^3$P$_0$ lattices independently, and can be performed with a strong laser on the clock transition. At the
