Our group studies quantum mechanical phenomena in nanoscale devices with a long-term view in quantum computing and simulation. Realizing a large-scale quantum computer is one of the grand scientific and technological challenges today, with broad possible applications in materials, health and energy. In our experimental set-ups, we confine individual electrons in semiconductors and control their internal magnetic moments, or spin. Their long coherence times and a compatibility with the fabrication methods used for normal computer chips mean these quantum dots make up a promising qubit platform for quantum technologies.
We fabricate quantum dot arrays using state-of-the-art nanofabrication technology provided by the Van Leeuwenhoek and Else Kooi laboratories, and manipulate and read out the electron spin qubits at millikelvin temperatures using dilution refrigerators, low-noise electronics, microwave techniques and nanosecond pulses.
Furthermore, we collaborate closely with a large web of experts, including our experimental and theoretical scientific colleagues in physics and electrical engineering at QuTech and abroad, the Netherlands Organisation for applied scientific research TNO as well as with Intel Corporation.
