Quantum information processing is expected to improve performing certain tasks in computation, communication, cryptography and metrology. The basic unit of quantum information is the quantum bit, which can be realized, for example, by the spin of a single electron. In these lectures, we first review the basic concepts of quantum information theory and a few important quantum algorithms (Deutsch, Grover, Shor). Then, we outline the theory of the fundamental physical mechanisms allowing for the initialization, control and readout of electron-spin-based quantum bits in solids, as well as the mechanisms leading to the loss of information encoded in these quantum bits. These mechanisms are associated to hyperfine, spin-orbit and electron-phonon interactions; the lectures will provide an introduction to these. If time permits, the basics of quantum bits based on superconducting circuit elements will also be covered. A goal of the lecture series is to provide an introduction to the physics of solid-state quantum bits, helping students to start a research activity in this field.


The course material relies on basic concepts of quantum mechanics and solid-state physics.
