Quantum Country

What Quantum Country actually is

Andy Matuschak and Michael Nielsen wrote an introduction to quantum computing that embeds short recall questions directly in the prose, then schedules them to reappear over following weeks. The subject is qubits and quantum circuits; the experiment is whether reading can be made to stick.

Why it is worth your time

Questions arrive mid-paragraph rather than at the end of a chapter, so you catch yourself having already forgotten something two screens after learning it.

Common questions

Yes. Quantum Country is free and does not ask you to register or hand over an email address before you can use it.

Yes. Quantum Country works on a phone as well as it does on a laptop.

What kind of site is Quantum Country?

We list it under Explain Everything — hard things, made suddenly obvious. Questions arrive mid-paragraph rather than at the end of a chapter, so you catch yourself having already forgotten something two screens after learning it.
