Notes from the field.
Working notes on post-quantum migration, problem encoding and the parts of quantum engineering that turn out to be harder than the physics. Written for engineers, with the details left in.

Quantum machine learning and optimisation: what is real, what is hype, and why everyone is racing
How quantum learning and optimisation differ from the classical versions, where they can help, what blocks deployment, and why governments and investors are moving fast.

How device fingerprints and physical unclonable functions work, why they differ, how PUFs are broken, what quantum PUFs improve, and what is still open.
