 The city is also home to three well-known think tanks – the Perimeter Institute for Theoretical Physics, an advanced centre for the study of foundational, theoretical physics and award-winning educational outreach in science; the Institute for Quantum Computing, based at the University of Waterloo, which carries out innovative research in the computer, engineering, mathematical and physical sciences; and the Centre for International Governance Innovation, an independent, nonpartisan think tank that addresses international governance challenges.The city is part of Canada's Technology Triangle (CTT), a joint economic development initiative of Waterloo, Kitchener, Cambridge and the Region of Waterloo that markets the region internationally.Despite its name, CTT does not focus exclusively on promoting technology industries, but on all aspects of economic development.
