Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.
LEARNING OUTCOMES
After completing the course the student
- Is familiar with the structure and postulates of quantum mechanics
- Can differentiate between the terms quantum-mechanical state and wavefunction
- Can solve the eigenstates and eigenvalues of the Schrödinger equation in simple situations and knows how to generalize the computation to situations where analytical solution is challenging.
- Can integrate the quantum evolution and the expectation values of physical quantities for simple systems.
- Can apply creation and annihilation operators to analyze one-dimensional harmonic oscillator.
- Can solve the eigenstates of the one-dimensional harmonic oscillator.
- Can predict measurent probabilities from a given quantum state.
- Can apply perturbation theory to compute eigensolutions in a situation where analytical solutions is challenging.

CONTENT, ASSESSMENT AND WORKLOAD
Content
Valid 01.08.2020-31.07.2022:
Postulates of quantum mechanics. Operators, eigenvalues and eigenfunctions. Expectation values and variance. Schrödinger equation. Properties of Hermitian operators. Qubit (two-level system). The superposition principle. Heisenberg's uncertainty principle. Commutator relations. Conserved quantities. Dirac notation. Hilbert space. Free particle and continuum energy spectrum. Particle in a potential well and discrete energy spectrum. Creation and annihilation operators and their relation to one-dimensional harmonic oscillator. The temporal evolution of quantum states and expectation values. Perturbation theory. Time development of expectation values (Ehrenfest's principle). The density matrix. Rotating frame.
Applies in this implementation:
We use heavily Dirac notation and tend to take a modern path on learning quantum mechanics. Thus we do not start from wavefunctions but show how they appear in certain cases from quantum states in the Hilbert space. We tend to put more emphasis here than in usual first courses in quantum mechanics to qubits which are important for quantum technology.
Assessment Methods and Criteria
Valid 01.08.2020-31.07.2022:
Teaching methods: lectures and exercises
Assessment methods: exercises and exam
Applies in this implementation:
An exam will be organized at the end of the course with maximum of 30 points. Successfully completed exercises will add a maximum of 6 points bonus to the points obtained from the exam.
Workload
Valid 01.08.2020-31.07.2022:
Lectures: 24 h, exercises: 12 h, exam: 3 h + independent work
DETAILS
Study Material
Valid 01.08.2020-31.07.2022:
Several options for recommened reading (R. L. Liboff: Introductory Quantum Mechanics, Ballentine: Quantum Mechanics - A Modern Development, Griffiths: Introduction to Quantum mechanics, Bolton & Lambourne: The Quantum World: wave mechanics)
Applies in this implementation:
Ballentine has a modern approach that is used in this course. It may however be a bit more challenging to read than some of the other books mentioned. Just pay attention to the mathematical notation we use in the lectures and stick to that. The books may have a slightly more sloppy notation (forgetting operator hats etc.) but one can still learn the content from them.
