The pioneering work of quantum computing engineer Craig Gidney could have huge consequences for us all. He tells Karmela Padavic-Callaghan why he is focusing on an algorithm that could end encryption as we know it WHEN I first started reporting on quantum computing several years ago, I had a lot to learn about the workings of these complicated, potentially groundbreaking machines and the cast of characters leading their development. Since then, I have been lucky to speak with many of them. But there is one person who has always eluded me – until now. Everyone with ties to quantum computing seems to know the name Craig Gidney. …
