Recent observations of excitonic coherences within photosynthetic complexes suggest that quantum coherences could enhance biological light harvesting efficiencies. Here, we employ optical pump–probe spectroscopy with few-femtosecond pulses to observe an excitonic quantum coherence in CdSe nanocrysta...
