Description: Information is stored and processed in hardware components. With their miniaturization the concept of classical bit must be replaced by the notion of quantum bit. After having introduced the basics of quantum physics for "discrete" systems, the basic spin 1/2 qubit and its manipulation on the Bloch sphere are illustrated. This course then develops the subjects of communications, cryptography, quantum correlations, and introduces elementary concepts of quantum physics with applications in information theory such as the density matrix and von Neumann's entropy. The course is intended for an audience with no knowledge of quantum physics and elementary knowledge of classical physics and linear algebra. Practical exercises, simulations and implementations on NISQ machines will also be covered during the semester. This course prepares students for more advanced quantum information classes.
Course and exercices are in presence.
Lecture notes (in french - we treat only a subset of these notes this semester)
Extra references for reading will also be given for some of the lectures (see in weekly schedule below)
Grading scheme: 1 midterm 20%, miniproject 10%, final exam 70%. The mini-project will start sometime during the second part of the semester.

This fall we treat material corresponding to a subset of these notes. Namely in the following order chapters 1, 2 (parts of them) and chapter 3; then chapters 5 and 6; then chapter 7; then chapters 15 and 16.
Note that chapters on quantum compuation (9, 10, 11, 12, 13, 14) are to large extent independent and treated in spring in class CS-308.
