Abstract

VTT micron-scale silicon photonics platform can play a significant role in the second quantum revolution, supporting not only quantum photonics but also solid-state quantum systems. Quantum photonics can benefit from the unique properties of the platform, a distinctive example application being quantum key distribution, where we are developing receivers to support its large-scale deployment. On the other hand, we are using our photonic integration technology also to aid scaling-up superconducting quantum computers, by controlling and reading the qubits in the cryostat through classical optical links. I will cover all these developments showing our recent results, ongoing activities, and future plans.
