Prepare the stack before the hardware arrives

Quantum-ready does not mean buying a machine this quarter. It means knowing which problems in your business are classical, which are combinatorial, and which secrets will not survive the next decade of cryptography.

Forward-thinking firms are already rewriting the algorithms they cannot afford to be late on ? identity, key exchange, and the models that sit next to them.

Post-classical is a planning problem

The leap is less about spectacle and more about inventory. If you cannot name the systems that would break, you are not preparing. You are hoping.
