Glossary
Every technical term this platform uses, with what it means and — the part that is harder to find elsewhere — the mistake it prevents. On this subject the intuitive reading is often the wrong one, so each entry says what a reader would otherwise get wrong.
Circuits
- Clifford
The family of gates that are easy to simulate classically — H, S, CNOT and their combinations.
Easy to get wrong: A circuit made only of Clifford gates needs no magic states and offers no quantum advantage. The T gates are what make a circuit both useful and expensive.
