The History of Quantum Computing
I was doing really short-term work in my lab on shoplifting tags. It turns out the tags were a terrible idea for sensing objects in a supermarket checkout but I realized they were computing. So with Eichtwein and a few other people we realized we could program nuclear spins to compute. And so that's what we used to do Grover's search algorithm and then it was used for a Shores factoring algorithm. The systems we did at nuclear magnetic resonance don't scale beyond a few qubits but the techniques have lived on.
