Research focuses on nanoscale / mesoscopic physics investigating quantum coherence, electron and nuclear spins and interactions in semiconductor nanostructures. Ongoing projects include

• spin qubits in coupled, laterally gated GaAs quantum dots
•  microkelvin temperatures in nanoscale sample
• topological quantum phases in the fractional quantum Hall effect
•  experiments investigating mesoscopic electron transport, including graphene research

We are interested in coherent manipulation of individual quantum systems in solid state nanostructures, with the goal of implementing quantum computation schemes.

Experiments investigate quantum transport through semiconductor nanostructures which are fabricated in house using high mobility 2D electron gas materials obtained from collaborating molecular beam epitaxy labs. Experiments are typically performed in dilution refrigerators at millikelvin temperatures in magnetic fields. Measurements are done using electronic low-noise techniques and may involve nanosecond-pulsing and microsecond readout schemes.
