Multiple Systems | Understanding Quantum Information & Computation | Lesson 02

Name: Multiple Systems | Understanding Quantum Information & Computation | Lesson 02
Uploaded: 2022-12-06
Description: A single qubit is only the beginning. John Watrous develops the mathematical language for describing several quantum systems together. This is a course-level bridge from individual states to multi-qubit reasoning, suited to viewers comfortable with vectors and tensor products. The focus is understanding the model, not claiming a new hardware result.
