Quantum Correlation among photons from a single Quantum dot at room temperature
Nature, 2000Co-Authors: Peter Michler, P. J. Carson, M. D. Mason, Ali Imamoglu, Geoffrey F Strouse, Steven K. BurattoAbstract:Maxwell's equations successfully describe the statistical properties1,2 of fluorescence from an ensemble of atoms or semiconductors in one or more dimensions. But quantization of the radiation field is required to explain the Correlations of light generated by a single two-level Quantum emitter, such as an atom, ion or single molecule3,4,5,6. The observation of photon antibunching in resonance fluorescence from a single atom unequivocally demonstrated the non-classical nature of radiation3. Here we report the experimental observation of photon antibunching from an artificial system—a single cadmium selenide Quantum dot at room temperature. Apart from providing direct evidence for a solid-state non-classical light source, this result proves that a single Quantum dot acts like an artificial atom, with a discrete anharmonic spectrum. In contrast, we find the photon-emission events from a cluster of several dots to be uncorrelated.

Quantum Correlation among photons from a single Quantum dot at room temperature
Nature, 2000Co-Authors: Peter Michler, P. J. Carson, M. D. Mason, Ali Imamoglu, Geoffrey F Strouse, Steven K. BurattoAbstract:The observation of Quantum dot resonance fluorescence enabled a new solid-state approach to generating single photons with a bandwidth almost as narrow as the natural linewidth of a Quantum dot transition. Here, we operate in the Heitler regime of resonance fluorescence to generate sub-natural linewidth and high-coherence Quantum light from a single Quantum dot. The measured single-photon bandwidth exhibits a 30-fold reduction with respect to the radiative linewidth of the QD transition and the single photons exhibit coherence properties inherited from the excitation laser. In contrast, intensity-Correlation measurements reveal that this photon source maintains a high degree of antibunching behaviour on the order of the transition lifetime with vanishing two-photon scattering probability. This light source will find immediate applications in Quantum cryptography, measurement-based Quantum computing and, in particular, deterministic generation of high-fidelity distributed entanglement among independent and even disparate Quantum systems.
