What?

This project investigates how we can develop quantum photonic technologies, such as quantum cryptography, sensing, and photonic computing, that are not only physically scalable but also ethically responsible. It combines ongoing theoretical work on strongly-interacting photonic architectures with ethical and historical research into how these technologies are developed and will be used in society.

Why?

Quantum technologies promise new capabilities for solving important problems such as development of new medicine and advanced sensing technology, but urgent questions arise: How do we develop them in a manner that ensures equitable access, environmental responsibility, and transparency? It is important to address both how we can realize future quantum advantages but also ask: Advantage for whom?

How?

Working with leading quantum physicists and historians in Rome and Denmark, I will advance novel theoretical models of quantum light-matter interactions and simultaneously develop new ethical frameworks grounded in quantum theory, history and social justice. Public workshops at the Danish Institute will promote inclusive debate on responsible quantum research and its societal implications.
