Arne Laucht is a Scientia Senior Lecturer within the School of Electrical Engineering & Telecommunication and Program Manager in the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T). His main research interests include: quantum physics, spin quantum computing, donor atoms in silicon, SiMOS quantum dots, dressed states, colour centres in silicon carbide and diamond, nanophotonics, and nanoscale device engineering.


Arne completed his PhD with summa cum laude in the group of Prof Jonathan Finley at the Technical University of Munich. His thesis was in the field of semiconductor quantum optics, where he worked on self-assembled InGaAs/GaAs quantum dots in photonic crystal cavities. He investigated non-resonant cavity emission [Kaniber, Phys. Rev. B (2008), Hohenester, Phys. Rev. B (2009), Laucht, Phys. Rev. B (2010)], electrically tunable strong coupling between the exciton and the cavity mode [Laucht, New Journal of Physics (2009), Laucht, Phys. Rev. Lett. (2009), Laucht, Phys. Rev. B (2010)], and single-photon emission from quantum dots in photonic crystal cavities [Kaniber, Phys. Rev. B (2008), Kaniber, New Journal of Physics (2009)] and into waveguide modes [Laucht, Phys. Rev. X (2012)].


At the University of New South Wales Sydney, Arne is working at the forefront of spin-based quantum computing in collaboration with the groups of Prof Andrea Morello and Prof Andrew Dzurak. He has contributed to many ground-breaking investigations and demonstrations in this research field:

Recently, Arne has started working on colour centres in diamond and silicon carbide with Dr Brett Johnson from the University of Melbourne, and Dr Thomas Volz and Dr Lachlan Rogers from Macquarie University. He is also the responsible person for the setup and operation of the Ultra-Low Temperature Optics (ULTO) Laboratory, an open-access facility that gives Australian and international researchers the possibility to conduct optical measurements at T < 100 mK.
