256 qubits?!?

QuEra Computing (https://www.quera.com/) has just launched with a 256-qubit computer. They call it a simulator, I guess because it uses a different underlying technology but it supposedly really is a 256 qubit quantum computer! See https://venturebeat.com/2021/11/17/quera-offers-new-quantum-advantage-based-on-harvard-and-mit-research and. yes, this has significant implications on security which impacts on blockchain, wifi security, network security, ssh, and pretty much everything else that relies on encryption. https://www.fastcompany.com/90698019/quera-quantum-computing-startup is another good and short article.

This is really pretty new (just announced today) and there aren’t a lot of analyses out there yet so I’d encourage you to do your own searches to keep up with it.
