Electron tunnelling limited coherence time of single quantum dot photodiode based qubit

We demonstrate technique to time-resolve the population inversion of a quantum dot exciton, and measure T1. Combined with measurements of the coherence time T2. T2 is limited by electron tunnelling from the dot.
