Birth Place:Pijnacker

Alma Mater:TU Delft
Awards:Spinoza Prize

Leo Kouwenhoven (born 10 December 1963) is a Dutch physicist known for his research on quantum computing.

Kouwenhoven grew up in Pijnacker, a village near Delft, where his parents ran a farm. After losing the admission lottery for veterinary medicine he decided to study physics at Delft University of Technology (TU Delft).[1]

In 1992 he received his PhD cum laude at TU Delft; his promoter was . In 1999 he became a professor at TU Delft. In 2007 he received the Spinoza Prize, the highest Dutch academic award. In April 2012 his TU Delft research group presented experimental results that provided potential "signatures" of Majorana fermion quasiparticles.[2] [3] [4] These Majorana quasiparticles would be very stable, and therefore suitable for building a quantum computer.[5]

In 2018 his research group claimed to have proved the definitive existence of Majorana particles in a Nature publication.[6] However, the results could not be reproduced by other scientists, and the article had to be retracted in 2021 due to "insufficient scientific rigour".[7] [8] [9] [10] The researchers had excluded data points that contradicted their claims, with the complete data not supporting their conclusions.[11]

Personal life

Kouwenhoven has six sisters and is married to Vrije Universiteit Amsterdam professor Marleen Huysman.
