    • 2 via currents through quantum dots in an ESR field (Refs. 24 and 31). However, using an optical detection scheme there is no need for contacting dots with current leads (thus reducing decoherence) and one can benefit from the high sensitivity of photodetectors.

    • Excitation of a charged exciton state containing an electron triplet would require an additional energy of ∼40 meV (Ref. 12) and can be excluded by the low laser bandwidth.
