Abstract
A brief overview of experimental and theoretical studies on using single neutral atoms trapped in arrays of optical dipole traps as qubits of a quantum computer is presented. Methods of loading and detection of atoms in the traps and of implementing two-qubit quantum gates via dipole-dipole interaction at short-term laser excitation of atoms to Rydberg states are discussed.
