Hybrid Photonic Quantum Computing with Semiconductor Quantum Dots

This colloquium talk by Pascale Senellart from CNRS, University Paris Saclay explores the development of hybrid photonic quantum computing platforms using semiconductor quantum dots. Discover how InGaAs quantum dots in cavities have evolved into efficient sources of highly indistinguishable single photons and plug-and-play devices. Explore the first quantum computing platform based on single photons and integrated photonic chips, along with proof-of-concept applications. Learn about various roadmaps for scaling up measurement-based quantum computing requiring photonic graph states, including recent milestones in generating spin-multi-photon entangled states. Examine the potential of hybrid quantum computing approaches that exploit both spins and photons, comparing full photonic approaches to hybrid ones for implementing logical qubits, and understand spin-optical approaches to quantum computing. The 55-minute presentation includes references to recent research publications in the field.
