1. A method comprising:
illuminating a quantum-state carrier (QSC) with electromagnetic radiation (EMR) comprising a plurality of illumination wavelengths including illumination wavelengths λ1, λ2 and λ3, the EMR stimulating the QSC to emit EMR of an emissions wavelength λ4, different from each of the illumination wavelengths λ1, λ2 and λ3, in the event the QSC was in a first eigenstate during the illuminating;
detecting whether or not EMR of the emissions wavelength λ4 has been emitted from the QSC; and
determining, based on the detection, whether or not the QSC was in the first eigenstate.
