Research group Trapped Ion Quantum Technologies

Due to a significant technical progress and precise engineering, we are nowadays able to manipulate individual quantum systems, like single atoms, with a precision that has been unthinkable a few decades ago.

Due to a significant technical progress and precise engineering, we are nowadays able to manipulate individual quantum systems, like single atoms, with a precision that has been unthinkable a few decades ago. Quantum technologies open many possibilities for applications, as for instance quantum computers that can solve problems intractable by classical computers, quantum-enhanced sensing and metrology, and quantum simulators that can improve our understanding of complex quantum phenomena. These applications are based on the special properties of quantum mechanics, like the exponential scaling of the Hilbert space, or the collective effects in entangled states.

Single-Shot Measurements of Phonon Number States Using the Autler-Townes Effect

Efficient and reliable detection of motional states is an essential component of many ion-trap experiments. In this recent work a new technique for measuring both Fock and thermal states, based on the Autler-Townes splitting, is demonstrated. The experimental work has been carried out in the group of Markus Hennrich at Fysikum, and was performed in collaboration with the groups of Celso Villas-Boas and Romain Bachelard in São Carlos, Brazil.

The Future is Quantum: 20 - 22 February 2023

An emerging field of physics and engineering is quantum technology, encompassing technologies that rely on the properties of quantum mechanics. Quantum computing being one example of these technologies, representing a paradigm shift for computing technology, since it can outperform much more than existing computers. On February 21 at 13:00, in the: Svedberg salen (FD5), AlbaNova, Professor Akira Furusawa from University of Tokyo, RIKEN Center for Quantum Computing will have a presentation with the title THE FUTURE IS QUANTUM - The development of Quantum Computing.
