Materials for the Quantum Information classes:

• Notes by Preskill (We did Chapter 6, Quantum Algorithms; Section 6.3.1)
• My notes (based on slides and Preskill notes with some details on the proofs)
• Exercises

If you are looking for some other materials make sure to check: Nielsen and Chuang, Quantum Computation and Quantum Information (I will not provide link, but you can easily Google it up)
