Quantum communication and information processing (QIPC) is a rapidly growing field that takes advantage of the most counter-intuitive
aspects of quantum mechanics to develop new technologies. In this framework, no-cloning theorem is exploited to communicate more
securely, while coherence and entanglement become resources to compute in a more efficient way than in the classical world. Moreover,
approaching the quantum limits paves the road to ultra-sensitive measurements in various fields of physics such as photonics, mechanics or
electrical engineering. In these various fields, the ability to beat decoherence, namely, to isolate and control quantum systems, was crucial.
Technological progresses have allowed fulfilling these challenging objectives, such that quantum protocols are now investigated in various
experimental setups.

This course will present an introduction to quantum information and more generally to quantum engineering, with examples taken from
photonics and superconducting circuits. It will expose the mains tools and concepts of quantum technologies, for students curious about this
intriguing topics, whether they envisage to embark in a PhD, or they just want to acquire a scientific background in this domain.
Basics of quantum optics and light-matter interaction will be presented. General concepts relevant for quantum information, e.g. quantum bits,
Bloch sphere or decoherence, will be introduced and illustrated using superconducting circuits and photonics based physical systems :

  • Theory : Quantum measurement theory, entanglement, decoherence, exemples of elementary quantum information protocols and quantum
  • Experimental aspects illustrated with superconducting qubits : Two-level systems, Bloch sphere, Rabi oscillations, Ramsey fringes,
    quantum limits of amplification
  • Experimental aspects illustrated with photonics : Coherent states, single photons, quantum cryptography, quantum teleportation
