Quantum Optics 2: Advanced Concepts and Technologies

This module introduces the formalism of quasi-classical states of radiation, explaining the connection between photons and classical light. It covers topics such as coherence, shot noise, and the Standard Quantum Limit (SQL).

This module focuses on multimode quasi-classical states of light, covering topics such as wave packets on beam-splitters, beatnotes between lasers, heterodyne detection, and the differences between coherent and incoherent multimode radiation.

This module introduces non-classical states of light, specifically squeezed states, which allow measurements below the Standard Quantum Limit. It covers applications in gravitational wave detection and other quantum technologies.

This module explores the concept of entanglement, Bell's inequalities, and experiments that have demonstrated the non-local nature of quantum mechanics. It focuses on pairs of photons entangled in polarization.

This module covers practical applications of entanglement in quantum technologies, including quantum cryptography, quantum teleportation, quantum networks, quantum simulation, and programmable quantum computing.
