Quantum Circuits | Understanding Quantum Information & Computation | Lesson 03

Name: Quantum Circuits | Understanding Quantum Information & Computation | Lesson 03
Uploaded: 2023-01-25
Description: Turn circuit diagrams into something you can follow. John Watrous connects sequences of quantum operations with the mathematics of states and measurements. This course lesson is a next step after qubit notation: pause at the transformations and work through the symbols rather than treating the diagram as a picture of a physical processor.
