content: Yes and no. It will work against public/private key encryption but not symmetric encryption.  Also, most quantum computing is bullshit. Google, IBM, and Rigetti in particular are hawking these tiny useless machines as though they’ve achieved “quantum supremacy”, even though it’s only for useless tasks with no value. They’re going to need to scale up to millions of qubits before it’s useful.  The only company scaling up their qubits and presenting an actual picture of business value is DWave but their machine is not going to be factoring anything like this anytime soon. Still, they have 5000 qubits in their new machine, hella better than google’s 53.
