*How many photons do you need to perform a multiplication operation optically?* It turns out that you can get away with less than 1 photon per scalar multiplication if you're doing large matrix-vector multiplications, as are used in neural networks. 1/3

The energy efficiency of computing is ultimately limited by noise, with quantum noise as the fundamental floor. What happens if we operate an optical neural network with such low power that each neuron activation is caused by just a single photon? 1/5

*What more can neuromorphic computing learn from neuroscience?* We were asked to write an opinion piece for the journal Neuron and took the opportunity to propose some questions to the neuroscience community: arxiv.org/abs/2310.18335 1/4

Delighted to share my research at the upcoming OQE seminar. Thanks to Prof. Dirk Englund for the invite! 📆Time: Next Tuesday, Dec 12 at 11AM ET. It's also streamed on Zoom so everyone can join online! oqe.nonlocally.org/event/2023-12-…

*Frequency-multiplexed squeezed light generation, manipulation, and detection for quantum technology* A distinctive feature of optics is that light can have very broad bandwidth. 1/
