  Atomic systems, ranging from trapped ions to ultracold and Rydberg atoms,
offer unprecedented control over both internal and external degrees of freedom
at the single-particle level. They are considered among the foremost candidates
for realizing quantum simulation and computation platforms that can outperform
classical computers at specific tasks. In this work, we describe a realistic
experimental toolbox for quantum information processing with neutral
alkaline-earth-like atoms in optical tweezer arrays. In particular, we propose
a comprehensive and scalable architecture based on a programmable array of
alkaline-earth-like atoms, exploiting their electronic clock states as a
precise and robust auxiliary degree of freedom, and thus allowing for efficient
all-optical one- and two-qubit operations between nuclear spin qubits. The
proposed platform promises excellent performance thanks to high-fidelity
register initialization, rapid spin-exchange gates and error detection in
readout. As a benchmark and application example, we compute the expected
fidelity of an increasing number of subsequent SWAP gates for optimal
parameters, which can be used to distribute entanglement between remote atoms
within the array.
