Resonantly excited emissions from a GaAs quantum dot and an exciton dipole moment

K. Kuroda, Takashi Kuroda, Kazuaki Sakoda +2 more

We report on observation of spontaneous emissions from a single quantum dot after resonant excitation. To capture weak emissions from a single quantum dot, reflection of an excitation laser was reduced by applying obliquely incident geometry and crossed polarization configuration. In addition, collected emissions were temporally resolved to be separated from residual reflection. These allowed us to realize a simple manipulation and read out of an exciton qubit. We observed an exciton Rabi oscillation in excitation amplitude dependence of the emission intensity. We determined an exciton dipole moment from the Rabi oscillation and from the emission decay time, independently. Comparison between the two values shows reasonable agreement.

We observed spontaneous emissions from a single quantum dot to read out a final state of an exciton qubit. To capture weak emissions from quantum dots, the reflection of an excitation laser were reduced by applying obliquely incident geometry and crossed polarization configuration. Rabi oscillations were observed in the emissions.

Final-state readout of exciton qubits by observing resonantly excited photoluminescence in quantum dots

K. Kuroda, Takashi Kuroda, K. Watanabe +4 more

The authors report on an approach to detect excitonic qubits in semiconductor quantum dots by observing spontaneous emissions from the relevant qubit level. The ground state of excitons is resonantly excited by picosecond optical pulses. Emissions from the same state are temporally resolved with picosecond time resolution. To capture weak emissions, the authors greatly suppress the elastic scattering of excitation beams, by applying obliquely incident geometry to the microphotoluminescence setup. Rabi oscillations of the ground-state excitons appear to be involved in the dependence of emission intensity on excitation amplitude.
