In our industry, one is the cryogenics system, which we make ourselves. There is electronics—controlled electronics and microwave electronics. Right now the biggest supply chain for that comes from the United States. It then comes down to nanofabrication. Right now, we're using a shared facility at Waterloo.
Again, the Achilles heel of all this goes back right now to electronics and building what we call field programmable gate arrays, FPGAs, and ASIC chips. This is not only in Canada; the whole world is dependent on Taiwan, to a great extent, especially the foundries at TSMC. I believe it is a geopolitical Achilles heel, because if China decides to invade Taiwan tomorrow, this could melt down a lot of economic sectors across the world.
This is also something we should really think about in a bigger strategic and economic context than just quantum.
