We talk to James Der Derian and Alex Wendt, editors of the Special Issue on Quantizing International Relations. They explain the motivation for their recent collaboration and why they believe International Relations still needs to grapple with the implications of quantum science, both at the level of social theory and the ramifications of resulting technological breakthroughs. We also discuss the origins of their long-standing interests in quantum theory, situating the latest work within their wider scholarly trajectories. Hosted by Antoine Bousquet.
