Quantum technologies

This course is specific to the NanoQuant program and offers a high-level fundamental training in the field of Quantum Technologies, i.e. current and future realizations of new technologies based on concepts such as quantum coherence and entanglement that allow to reach functionalities and sensitivities that exceed their classical analogues.

In the continuity of the M1 courses in quantum physics(Atoms, Molecules and Radiation in semester 1, and Advanced Quantum Mechanics in semester 2), the students will follow in the second year a specific teaching entitled Quantum Technologies, dealing with the modern stakes and problems linked to the "second" quantum revolution and its developments in communication, sensors and quantum computation: theory of open quantum systems, density matrix, elements of quantum optics, quantum entanglement and quantum coherence. This teaching will include a series of practical works specific to Quantum Technologies and will be completed by seminars.

• Atoms, Molecules and Radiation
• Analytical mechanics
• Advanced quantum mechanics
• Elements of physics of light-matter interaction

Recommended Prerequisites:
