Playing Pool with $|ψ\rangle$: from Bouncing Billiards to Quantum Search

In ``Playing Pool with $\pi$'' \cite{Galperin}, Galperin invented an extraordinary method to learn the digits of $\pi$ by counting the collisions of billiard balls. Here I demonstrate an exact isomorphism between Galperin's bouncing billiards and Grover's algorithm for quantum se...
