Current status of the research on the use of single neutral atoms, captured in optical traps, as a quantum computer’s qubits, is briefly reviewed. The specifics of qubits based on cold atoms and t quantum logical operations via dipole interaction by short-time laser excitation in a Rydberg state are discussed. The latest experimental results of the observation of dipole interaction between two Rydberg atoms and of atoms’ entangled states in a ground state are given.
