This is, frankly, incredible. When I first heard the result, I couldn't imagine how it was possible. But it's true! The essay explains why it's true, how it's done, and even sketches how one might have come to discover the search algorithm.

The essay isn't just about the search algorithm. It's also about learning to think in the quantum realm. Think of it as an introduction to quantum algorithm design, introducing many techniques which can be used in other algorithms as well.

It's about beginning to go beyond our everyday classical intuition, and to develop tools and heuristics for thinking about the quantum world.

As with our earlier essay, on "Quantum Computing for the Very Curious", this essay is presented in an experimental mnemonic medium.

This new medium bakes in the ideas of spaced-repetition testing, and - we hope and believe! - will make it almost effortless to remember what you read for the long term.

There's no code or anything to confirm. You should be all set!

Got it. Just went through the first review.
I had big problems by misclicking/mistapping on whether i remembered the answer or not. And I could not go back to the previous question to correct my feedback.
Undo functionality/Review set again would help from UX perspective.

Thanks, that’s good to know. Can you say more about the mistapping? Was it that you weren’t trying to tap on anything—just adjusting your grip, say—yet a review was triggered? Or that you accidentally tapped ✅ when you meant ❎?

On mobile screen it was the former - dint mean to tap anything but triggered a review. Usually triggered while trying to scroll up to read the question after tapping the feedback for previous question.
The latter (wrong selection of tick or cross) happened often on desktop.

That's very helpful, thank you. You mentioned "scroll up," which surprises me a little: the review sessions shouldn't involve any scrolling. Could you let us know what kind of device you were reviewing on?
I meant scrolling while going through the essay. Sorry - my bad.
So the card would be obscured by the browser controls depending on which direction i am scrolling in. Attaching screenshots - let me know if it helps.
The review session i did on desktop only so far.
