Current research

• The coherent control and entanglement of electron spins in coupled quantum dots, aimed at the realization of an elementary quantum computer. See the page of the Delft spin qubit project,
• Spin coherence and confinement of electrons in graphene, a single monolayer of graphite, in which electrons exhibit features of relativistic particles (see also our FOM graphene program website).

Past research (PhD work)

• NMR quantum computation experiments, including prime factorization of the number fifteen (15=3x5) using Shor's algorithm, executed on seven nuclear spins in a molecule as quantum bits. (Stanford University and IBM Almaden, 2001)
