Seminar MSc 1/2 - Quantum technologies
The first Quantum Revolution gave us new rules that govern physical reality. These were exploited to understand many questions in solid state physics, high energy physics and optics. It caused a transformational change to science, technology and society by providing us with things like transistors, computers, iPads, the laser and so on. The next Quantum Revolution is now on its way. The European Union and many national activates are spending significantly more than one billion Euros within the next ten years to develop tools and devices that “really” exploit the quantum character of our world. The goal is to produce quantum computers and quantum simulators, quantum sensors and quantum communication devices that might in the future impact large areas of daily life. This seminar intends to give an overview over this topic. We will explore individual examples where quantum technologies are already used today and hope to give you an overview of what to expect from quantum technologies in the coming years.
The seminar is a joint initiative of all QUANTUM groups and will be organized by Patrick Windpassinger (windpass@uni-mainz.de). The approx. 30 minutes talks should be given in English.

Topic: Long-lifed coherent states for nuclear- and particle physics, cosmology and quantum information science
Quantum technolgies nowadays span the full range of fundamental research to applied physics and metrology.
In areas of fields of physics traditionally regarded as independent, unique opportunities often arise to experimentally study fundamental questions (e.g. why is there any matter at all?). Long-lifed coherent states play a crucial role in this endeavour
This seminar aims to present the full range of concepts and the application of quantum methods. The topics are therefore broadly chosen to highlight the existing connections. The individual topics are supervised by individual members of the QUANTUM working group.
A list of possible seminar topics (but not limited to these):
- Quantized states of neutrons bound in the earth's gravitational field: search for exotic interactions (Fertl)
- Measurement of gravitational waves with light interferometers (Walz)
- Mass spectroscopy on rare elements (Wendt)
- Determination of the magnetic flux quantum with superconducting interferometers (Bluemler)
- Quantum logic clocks - the most accurate ion clocks in the world (Poschinger)
- Optical lattice clocks (Windpassinger)
- Measurement of the magnetic moment of the (anti-)proton (Walz, Smorra)
- Determination of the Rydberg constant (Pohl)
- Measurement of nuclear charge radii with muonic atoms (Pohl)
- Measurement of the anomalous magnetic moment of muons and electrons (Fertl)
- Are natural constants really constant? Variation of the fine structure constant (Budker)
- Measurement of neutron life time (Fertl)
- Neutron interferometry (Fertl)
- Quantum-non-demolition mesurements, quantum noise squeezing and entangles states for improved measurement senistivity (van Loock)
- Optical magnetometer arrays to search for domain walls, axions, ... (Budker)
- Magnetic microcalorimeters for high-precision spectroscopy of X-rays and decay electrons (Fertl)
- ADMX - Josephson junctions and quantum limited amplifiers for a axion search (Fertl)
- Muonic X-rays to study the weak interaction (Pohl)
- Precision gravimetry for fundamental physics (Budker)
- Measurement of the permanent electric dipole moment of the electron using ultracold molecular beams (Fertl)
