Content, Learning Outcome and Preconditions

Content

Recent breakthroughs in the control of individual quantum systems have fostered the dream of a ‘second quantum revolution’, in which fundamental quantum properties such as nonlocality or entanglement are used in novel devices in order to provide functionalities inaccessible by any classical device. The envisioned applications include the simulation of chemical reactions and complex solid state properties, measurements with unprecedented precision, provably secure encryption and a fundamental enhancement of computational power.

The exploration of different physical systems that serve as the ‘quantum hardware’ enabling these applications is a fast-growing field of current quantum science. The key challenge is to initialize, control, couple, and readout fragile quantum states in a technologically feasible way. The goal of this seminar is to summarize the variety of techniques and physical systems that give access to such control, ranging from trapped atoms to superconducting circuits, and from optical photons to quantum dots and single defect centers in selected crystals. The seminar will try to work out the similarities and differences of these approaches, and to identify the major open challenges on the way to larger and larger quantum-controlled systems. In addition, dedicated talks will address the following topics:

-          What is a quantum bit? What makes it different from a classical bit?

-          How can a quantum state be measured and characterized?

-          What is entanglement? How can it serve as a resource?

-          What is decoherence, and how can it be reduced?

-          What is a quantum logic gate? How can quantum logic gates be implemented?

The seminar is on Wednesday, 8.00, in PH II 127, Seminarraum E11

Learning Outcome

After successful participation in the module the student can use the basic methods of literature retrieval, condense their knowlegde from scientific papers into a presentation and obtain presentation skills.

They have learned about recent topics in quantum information processing.

Preconditions

Completed B.Sc. studies.

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

The learning outcomes of this module will be developed through the literature search, the study of literature, the preparation of the presentation, the discussion with the teacher, the talk itself, answering questions about it, and intense 30min discussions in small groups about the carry-home messages of each talk.

Module Exam

Description of exams and course work

In the course of the seminar each student individually prepares a talk on a topic of current research. Based on this talk the learning outcome is tested.
