My first publication as co-corresponding author, alongside my previous postdoc advisor Moungi Bawendi! We generalize our denoising neural network model for photon correlation Fourier spectroscopy, successfully applying it to >80 quantum dot experiments.

Single coherent photons on demand are essential inputs for many applications of quantum optics, including for linear optical quantum computing. One critical parameter when assessing the potential of...

More quantum emitters + deep learning, accepted for the AI4Mat workshop at @NeurIPSConf! We develop latent neural ODE models that predict entire interferometric photon correlation experiments from only 10 measured inputs, allowing for up to x20 speedups:

Out now in APL Machine Learning! We (@NRC_CNRC @JCEP8) applied deep 3D-to-2D U-Nets to perform phase retrieval, combining randomly phase modulated frames with as few as ~100 photons, achieving lower error than conventional state-of-the-art methods:

An amazing day for quantum dot science! I was very lucky to be a postdoc at MIT in Moungi's lab, and it was a privilege to work on such exciting research under the tutelage of an incredibly brilliant, kind, and inspiring scientist.

We used this ML-augmented technique to measure the linewidths and optical coherence times (T2) of a CsPbBr3 quantum dot, and found excellent agreement with the T2 value measured directly using Hong-Ou-Mandel two-photon interference (.

Deep learning + single dot spectroscopy! Now online @PhysRevLett, we developed a de-noising neural network to extract time-resolved lineshapes of single quantum emitters at timescales of 10-100 nanoseconds using photon correlation Fourier spectroscopy:

These are among the narrowest linewidths reported for colloidal QDs, and InP/ZnSe/ZnS QDs appear robust against spectral diffusion: they show minimal broadening on timescales as long as 50 ms; orders of magnitude longer than CdSe/CdS dots or CsPbBr3 nanocrystals.

Thrilled to share our work published in @NatureNano where we report ~5 µeV linewidths and 200+ ps optical coherence times from single InP/ZnSe/ZnS colloidal quantum dots! A fantastic collaboration with @Samsung, co-led by @DavidBerkinsky @ChemistryMIT .

Hong-Ou-Mandel interference in colloidal nanocrystals! Great work led by @KapKapRevenge showing the first demonstration of HOM in CsPbBr3 perovskite nanocrystals, with visibilities up to 0.56±0.12 - without any radiative enhancement.
