Please contact one of the senior members if you are interested in carrying out a Bachelor or a Master degree project  in one of the groups of our research division. Below you find suggestions for Bachelor and Master projects in

  • Trapped Ion Quantum Technologies
  • Quantum Photonics

  • Theory in quantum optics, quantum information and gravity

 

Possible experimental Master projects on Trapped Ion Quantum Technologies:

  1. Ion trap design and setup (for students who like to build the bits and pieces of an experiment). Design and set up of an ion trap for quantum information experiments. Build a vacuum chamber with the ion trap inside, set up the optics for ion trapping, and get everything to run.
  2. Loading, initialization and quantum control of multi-qubit ion strings
    Each ion in a larger ion crystal can serve as a quantum bit of a quantum computer. Before starting a quantum calculation, ions first need to be loaded as a isotope-pure crystal, cooled by laser light close to the motional ground state and initialized in a well-defined electronic state. Quantum calculations then consist of sequences of addressed and coherent laser pulses. The goal of this Master project is the realization of loading, initialization and quantum control of multi-qubit ion strings.
     

Possible experimental Bachelor projects on Trapped Ion Quantum Technologies:

  1. Characterization of UV optical fibres. We are using self-made optical fibres for our UV lasers for Rydberg excitation. The goal of this Bachelor project is to characterize new UV fibres in terms of losses, coupling efficiency and stability.
  2. Laser intensity stabilisation. Trapped ions are manipulated by laser pulses. Intensity fluctuations of these laser lead to imprecise state manipulation of the ions. The objective of this Bachelor project is to set up an intensity stabilisation for our qubit laser to make the qubit manipulation more precise.

Possible experimental Master projects on Quantum Photonics:

  1. Quantum light generation in quantum dot systems (60 credits – mostly experimental).
    Quantum dots are highly efficient sources of quantum light. They are operated in a cryogenic environment and when excited by laser light they emit light with strong quantum properties. The objective of this thesis is the coherent excitation and characterisation of quantum dots in novel devices for quantum communication and information processing.
  2. Propagation of quantum light in real-life networks (60 credits experiment + theory).
    Quantum networks require quantum light for secure communication and cryptography. Propagation losses and noise affect the quantum properties and in return also the security of quantum communication protocols. The objective of this thesis is the theoretical and experimental investigation of quantum properties of light, how these properties are preserved during propagation in real-life networks.
