Abstract: In accordance with a method for individually addressing qubits in a set of qubits, a plurality of qubits is provided that each have two internal states representing a unit of quantum information. A transition between the two internal states of each qubit is caused by a two-photon Raman transition. Each of N ones of the qubits in the plurality of qubits are individually addressed using one of N pairs of laser beams, respectively, N being an integer greater than or equal to two. The laser beams in each of the N pairs have a frequency difference equal to a qubit transition frequency that represents a difference in frequency between the two internal states of the qubits. The laser beams in each pair of laser beams operate at different frequencies than the laser beams in every other pair of laser beams.
