Instead of sponsored ad reads, these lessons are funded directly by viewers: https://3b1b.co/support An equally valuable form of support is to share the videos. The subtitles on this video were done using AI, and are likely imperfect, but they are open for community corrections at https://criblate.com/ Adam Brown's paper on the connection between Grover's Algorithm and block collisions: https://arxiv.org/pdf/1912.02207 If you want to learn the relevant underlying quantum mechanics here, a very friendly resource is the course Mithuna at Looking Glass Universe is currently putting together. See, for instance, this explainer of a qubit: https://youtu.be/kgSVkVNxXyU If you want to learn more about the fundamentals of quantum computing, my friends Michael Nielsen and Andy Matuschak put together this wonderful resource, aimed at ensuring long-term memory of core concepts: https://quantum.country/ BBBV Theorem: https://www.scottaaronson.com/qclec/23.pdf Timestamps: 0:00 - Misconceptions 6:03 - The state vector 12:00 - Qubits 15:52 - The vibe of quantum algorithms 18:38 - Grover’s Algorithm 29:30 - Support pitch 30:11 - Complex values 31:27 - Why square root? 34:01 - Connection to block collisions 35:08 - Additional resources ------------------ These animations are largely made using a custom Python library, manim.
