additional remarks Semiconductor based quantum photonic devices and circuits are highly promising for controlling light-matter interactions at the limit of single photons and individual electrons. Such systems provide wide scope for implementing various quantum (Q) information technologies, including Q-communication, Q-computation and exploring the fundamental properties of Q-matter. For example, they can be used for (i) the deterministic generation of quantum states of light and the efficient storage & retrieval of quantum information in memories built from trapped electron and nuclear spins, (ii) the construction of stable quantum photonic circuits for quantum information processing and simulation and (iii) engineering of the 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 introducing key aspects of quantum mechanics including the general formulation of describing quantum states (stationary and time-dependent), the quantum mechanics of discrete quantum systems (qubits), a crash course in Dirac notation and quantisation of the electromagnetic field. We will then continue to discuss optical control methods available from the "quantum optical toolbox" key theoretical aspects pertaining to light-matter couplings at the quantum limit. After this, we move on to 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 QED Technological 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 Technologies Quantum 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)conductors Quantum 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
