You’ve seen the stories—in the Financial Times, Technology Review, CNET, Facebook, Reddit, Twitter, or elsewhere—saying that a group at Google has now achieved quantum computational supremacy with a 53-qubit superconducting device. While these stories are easy to find, I’m not going to link to them here, for the simple reason that none of them were supposed to exist yet.
Boston-based Aliro Technologies, a spinout of the NarangLab at Harvard University, aims to develop a hardware-agnostic quantum computing software platform. Its vision is to create the “Java of quantum computing”. The startup has just closed […]
