Welcome to the web page of the Quantum Coherence Lab

Research focuses on low-temperature quantum transport experiments investigating quantum coherence, electron and holes spins as well as nuclear spins and interactions in semiconductor nanostructures. Ongoing projects include

  • spin qubits (electrons, holes) in semiconductor nanostructures
    for quantum computing
    • Ge/Si nanowires gate defined dots
    • Si finFET transistors
    • Ge/Si planar gate defined dots
    • GaAs quantum dots
  • microkelvin temperatures in nano samples
    for quantum transport experiments
  • nanowires and 1D systems for novel quantum matter
    such as helical states, nuclear spin helices, Majorana fermions, parafermions and other exotic quantum phases
  • tunneling spectroscopy to probe edge states
    such as (fractional) quantum hall states and other edge states in exotic materials such as topological insulators
  • spin-orbit coupling in semiconductor quantum wells and wires
    in various materials and nanostructures, to study strong spin-orbit coupling and spin helix physics in quantum transport

Experiments investigate quantum transport in semiconductor nanostructures which are fabricated in-house or in collaborations. Experiments are typically performed at kelvin or millikelvin temperatures in magnetic fields. Measurements are done using electronic low-noise techniques and may involve nanosecond-pulsing and microsecond readout schemes. An ERC Starting Grant from the first ERC call was awarded to our group and boosted our research from 2008-2013 (press release)
