Leo P. Kouwenhoven (born December 10, 1963 in Pijnacker ) is a Dutch physicist. He deals with quantum transport in solids.

Live and act

Kouwenhoven received his diploma in applied physics from the TU Delft in 1988 ( Discovery of quantized conductance in quantum point contacts ) and received his doctorate cum laude in 1992 from JE Mooij ( Hans Mooij ) at the TU Delft ( Transport properties of electron-waves and single-charges in semiconductor nanostructures ). From 1992 to 1994 he was a post-doctoral student at the University of California, Berkeley , with Paul McEuen . From 1999 he was Professor of Physics at the TU Delft, since 2008 with the title of University Professor. There he heads the quantum transport research group and is also head of the Solid State Quantum Information Processes research group in the Netherlands , which is funded by the FOM (Dutch state research company) for ten years with EUR 1 million a year. In 2000/2001 he was visiting professor at Harvard University . He is also at the Kavli Institute of Nanoscience in Delft. In addition to the NanoScience Center in Harvard, he also works closely with the University of Tokyo, where he was a visiting scientist in 1991.

He is concerned with quantum transport in the nanometer range in solids, for example quantum dots , semiconductor nanowires and carbon nanotubes. He studied the most diverse quantum phenomena in his laboratory and is looking for applications in quantum optoelectronics and in quantum information theory (whereby the spin of electrons in quantum dots should be used as qubits, suggestion of a quantum computer according to Daniel Loss , David DiVincenzo ). In their experiments, his laboratory also tries to detect Majorana fermions in superconductivity in nanowires . In 1988 he was involved in the discovery of conductance quantization in quantum point contacts (together with Bart van Wees, Carlo Beenakker and others).

In 2007 he received the Spinoza Prize . In 2006 he became a member of the Royal Netherlands Academy for Arts and Sciences (KNAW), of which he was a research fellow from 1993 to 1998, and he has been a member of the Netherlands Academy for Technology and Innovation (ACTI) since 2008. In 2002 he received the Sackler Prize in Physics, and in 2014 he was elected as a foreign member of the National Academy of Sciences .

Ronald Hanson is one of his PhD students .
