Microsoft places its bets on quantum computing

#artificialintelligence 

At its Ignite conference, Microsoft today put its stake in the ground and discussed its progress in building a quantum computer and giving developers tools to experiment with this new computing paradigm on their existing machines. There's a lot to untangle here, and few people will claim that they understand the details of quantum computing. What Microsoft has done, though, is focus on a different aspect of how quantum computing can work -- and that may just allow it to get a jump on IBM, Google and other competitors that are also looking at this space. The main difference between what Microsoft is doing is that its system is based on advances in topology that the company previously discussed. Most of the theoretical work behind this comes from Fields Medal-recipient Michael Freedman, who joined Microsoft Research in 1997, and his team.
