Name: Quantum Channels | Understanding Quantum Information & Computation | Lesson 10
Uploaded: 2024-06-05
Description: How do you describe a quantum system that is not perfectly isolated? This John Watrous lesson introduces quantum channels after the density-matrix framework. It is a technical route into operations and noise, helping mathematically confident viewers move beyond the idea that every change is an ideal gate on a closed system.
