Each page covers what the project is, how it works, and where it stands.
My program finds the cheapest way to run a home solar battery - it saves a real Colorado home $1.93 on a typical summer weekday. I then ran the same problem on a real quantum computer to measure how it does against an answer I already knew. It only handled a day cut down to 2 decisions instead of 24; noise buried everything bigger.
ECDSA is the piece of math that decides who owns every Bitcoin: it stops anyone else from spending your coins. A big enough quantum computer could break it. For ECDSA.fail, an open competition measuring how big, I reproduced the best known circuit and mapped why its cost is at a floor.
