Learn the Basics / Inside a Quantum Computer

Inside a Quantum Computer

What that famous golden chandelier actually is, how a computer can try many answers at once and still hand you the right one, and (honestly) what quantum computers are good at and what they'll never be.

After Basics · ~20 min · 3 sections, each ending in a mini quiz · final test at the end

Do the sections in order: each one leans on the last. A quiz pass is 60%, and you can retake any quiz forever: every attempt draws a different mix of questions.

1. The Golden Chandelier

It's mostly a fridge. A really, really good fridge.

5 slides · then a 5-question quiz

2. How It Thinks

All the answers at once: then make the wrong ones cancel.

5 slides · then a 5-question quiz

3. Good At, Bad At

Honest answers: no, it won't run your games better.

5 slides · then a 5-question quiz

Final test

10 questions covering the whole course, pass with 60%. Retake as often as you like; every attempt is a fresh draw.
