additional remarks Semiconductor-based quantum devices are highly promising for controlling light-matter interactions at the limit of single photons and individual electron spins. Such systems provide broad scope for implementing various quantum (Q) technologies, including Q-communication, Q-computation and exploring the fundamental properties of quantum many-body systems. For example, they can be used (I) to trap and prepare the quantum state of individual spins that can act as spin-photon interfaces, (ii) for the deterministic generation of quantum states of light including single photons and entangled photon pairs, (iii) for the storage and retrieval of quantum information in static quantum memories built from trapped spins (electrons and holes), sometimes coupled to nuclear spins, (iv) the construction of stable quantum photonic circuits for photon-based quantum information processing and simulation and (iii) mediating effective photon-photon interactions in optical cavities and (iv) their use for preparing and studying quantum many-body physics in strongly interacting quantum fluids of light.Our lectures will begin by motivating our lectures and we will review key concepts of quantum physics as applied to stationary qubits and the electromagnetic field. We will then continue to discuss key properties of optically active semiconductors (III-V, group IV and 2D materials), methods for realizing nanostructures with a discrete electronic orbital spectrum, before moving on to explore key theoretical aspects pertaining to light-matter couplings at the quantum limit. We will explore technological and materials aspects, including the techniques used to produce semiconductor-based quantum light sources and quantum photonic circuits, as well as quantum detectors of light that can be integrated into nanophotonic circuits. In the second half of the module, our attention will shift to the application of these key concepts in the fields of Q-communication, -metrology and -sensing. Finally, our attention will turn to strongly interacting quantum fluids of light in nano-structured semiconductor micro-cavities. Specific topics will include:Fundamentals- Historical motivation, scientific technological context- Introduction to key concepts in quantum mechanics (applied to semiconductors and solids)-The quantum optical toolbox for near isolated quantum systems-Jaynes-Cummings model for cavity-QED-Quantum nonlinearities-Open quantum optical systems - quantum master equations-Strong and weak coupling regimes of cavity QEDTechnological Aspects-Quantum emitters: self-assembled quantum dots + defects in crystalline solids.-Photonic modes in resonators, waveguides and directional couplers.-Material systems for integrated quantum photonics (silicon-based, III-V, diamond, lithium niobate and silicon-carbide)-Quantum Photonic TechnologiesQuantum cryptography using discrete and continuous variables-Photon-based quantum simulation (Boson sampling)-Linear Optics Quantum Computation (LOQC)-Photonic cluster states and measurement-based approaches for QIP-Quantum limited detectors based on semi-(super)conductorsQuantum Fluids of Light-Semiconductor microcavity designs (planar, tunable, plasmonic and hybrid)-Microcavity polaritons-Bose-Einstein condensation of MC-Polaritons (coherent and incoherent pumping)-Superfluid hydrodynamics of the photon fluid-Strongly correlated photons
