Driven-dissipative quantum state preparation (P2)

The theoretical project in the group of A. Eckardt at TU Berlin concerns protocols for the controlled preparation of correlated target states (like topological states, relevant for quantum simulation and error correction) by combining periodic driving and reservoir engineering in artificial quantum systems, like superconducting circuits [project description P2]. For further information please contact Andre Eckardt (TU Berlin, ITP) (email: eckardt@tu-berlin.de, phone:+49 30 314 23034).

Photonic quantum computing (P3)

The research group on quantum information and many-body theory (Jens Eisert) deals with notions of quantum computing and communication and the study of complex quantum systems. The project is concerned with identifying ways of dealing with new kinds of noise robust ways of quantum computing and simulation with integrated optical architectures [project description P3].

Quantum Communication at Telecom Wavelengths (P5)

Embedded within the Quantum Communication Systems group led by Dr. Tobias Heindel, this project aims at implementations of quantum cryptography at telecom wavelengths. Comparative studies of different types of protocols and quantum light sources (based on quantum dots and non-linear crystals) are envisioned in a quantum network testbed in Berlin city [project description P5].

For further information please contact Tobias Heindel (TU Berlin, IFKP) (email: tobias.heindel@tu-berlin.de).

Development of a quantum-limited heterodyne spectrometer on a stratospheric balloon (P6)

The research group Optical Systems led by Prof. Dr. Dr. h.c. H.-W. Huebers deals with air- and spaceborne optical systems for atmospheric sensing. The goal is to develop a terahertz heterodyne spectrometer with quantum-limited sensitivity for the detection of atomic oxygen in the mesosphere and lower thermosphere of the Earth, relevant for a future satellite mission [project description P6].

For further information please contact Heinz-Wilhelm Huebers (DLR, HU Berlin) (email: heinz-wilhelm.huebers@dlr.de, phone: +49-(0)30-67055596).

Nonequilibrium atom-surface interactions with unconventional materials (P7)

The Theoretical Optics & Photonics group (F. Intravaia and K. Busch) at the Humboldt University of Berlin is seeking a highly motivated scientist for theoretically investigating nonequilibrium atom-surface interactions in systems involving unconventional materials (e.g., non-reciprocal materials, topological insulators) [project description P7].

For further information please contact Francesco Intravaia (email: francesco.intravaia@physik.hu-berlin.de, phone: +49 (0)30 2093 82457).

Terahertz spin dynamics in novel quantum materials (P8)

In novel antiferromagnets, one can rotate electron spins altogether by simply applying electric rather than magnetic fields. In this PhD project, you will use terahertz electromagnetic pulses to control and understand antiferromagnetic spin dynamics and explore interesting applications such as terahertz field sampling [project description P8].

Testing Fundamental Quantum Mechanics using Atom Interferometry (P9)

This project is a joint endeavor of the Optical Metrology and Integrated Quantum Sensor groups at HU-Berlin to use the state-of-the-art cold atomic fountain interferometer GAIN for high-precision tests of quantum mechanics, specifically the linearity of the Schroedinger equation and wavefunction collapse theories. [project description P9].
