Single atoms trapped in dipole microtraps or optical tweezers are one of the most promising platforms for quantum computing. We will describe the system for digital gate-based quantum computing using hyperfine states of single Rubidium atoms as qubits. We will discuss the principles and methods for assembling the uniformly filled arrays of single atoms and the achievable parameters of atomic quantum registers. We will report our recent experimental results on characterizing the errors of single qubit gates with randomized benchmarking, achieving the error rate per gate below 10-3 and discuss the limitations related to single qubit addressing and gate time. We will also briefly describe our experimental progress towards implementation of two-qubit gates based on Rydberg excitation of single atoms with individual addressing and highlight the perspectives of improving the gate fidelity and scaling up the register size.
