Abstract Quantum computers operate in a manner so different from classical computers that our intuition for understanding the process of quantum computation is challenged. This not only makes it hard to develop new quantum algorithms, but also makes quantum computation a difficult subject for students. Here, we show that the time evolution of a particle on a ring with a coil through it performs the key quantum algorithm known as quantum phase estimation. The example uses the Aharonov–Bohm effect, and the aim is to help students build a physical intuition for quantum algorithms.
