Course specific prerequisites
FUF040 Quantum Physics or equivalent is required. The following courses are recommended: TIF101 Applied Quantum Physics and TIF290 Quantum Mechanics.Aim
The course introduces how one can describe, manipulate, and detect quantum mechanical systems such as single atoms and photons, and how advances in the control and measurement of these systems are driving the so-called second quantum revolution through the four pillars of quantum technologies: quantum computation, quantum simulation, quantum communication, and quantum sensing. This revolution is being pushed forward by large research initiatives worldwide, such as the Wallenberg Centre for Quantum Technology (WACQT) in Sweden, of which Chalmers is the main node, the EU Quantum Flagship in Europe, and many more. The course gives an overview on this very active field of research and connects via lectures, exercise sessions, and a laboratory session in a state-of-the-art facility to ongoing research on quantum mechanical superconducting circuits, microwave photons, and optomechanical systems.Learning outcomes (after completion of the course the student should be able to)

Content
In the first part of the course, we will study the foundations of quantum optics, that is, how matter (atoms) interacts with an electromagnetic field at the quantum level (photons). We will study both the semi-classical and the full quantum light-matter interaction and get to know different quantum states of light and their quantum optical description. In experiments that implement these building blocks of quantum optics, one can use a diverse set of physical systems, for example, atoms, trapped ions or artificial atoms such as superconducting microelectronic circuits that possess quantum mechanical properties like atoms.In the second part, we will apply the formalism of quantum optics to various physical platforms including superconducting circuits, trapped ions, cold atoms, nitrogen-vacancy centers in diamond and mechanical resonators . Here the goal is to understand how quantum effects can be exploited to build novel devices and to use novel measurement techniques, that are key for all four pillars of quantum technology. Quantum computers allow to perform certain computations or simulations by using quantum algorithms that are faster than the corresponding classical algorithms. The development of quantum simulators can be traced back to R. Feynmans intuition that carefully engineered quantum systems could be used to efficiently simulate materials and molecules, potentially leading to breakthroughs in material science and chemistry. Quantum communication systems allow performing quantum key distribution over absolute safe channels and can connect quantum computers over large distances. Finally, quantum sensors take advantage of quantum phenomena such as state superposition and squeezing to build sensors, imaging systems, and metrological standards with unprecedented accuracy.

Examination including compulsory elements
The course examination will consist of: 4 obligatory hand-ins, lab report and exam. To pass the course, you need to obtain at least 40% of the points on the exam and participate in the lab and submit a written lab report. The grade will then be based on: exam (50%), hand-ins (35%) and lab report (15%).The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
