  I discuss a variety of issues relating to near-future experiments
demonstrating fault-tolerant quantum computation. I describe a family of
fault-tolerant quantum circuits that can be performed with 5 qubits arranged on
a ring with nearest-neighbor interactions. I also present a criterion whereby
we can say that an experiment has succeeded in demonstrating fault tolerance.
Finally, I discuss the possibility of using future fault-tolerant experiments
to answer important questions about the interaction of fault-tolerant protocols
with real experimental errors.
