Ronald Hanson (* 1976 ) is a Dutch physicist.

Hanson studied applied physics at the University of Groningen with a master's degree in 1999, spent a year in Japan and completed his doctorate in 2005 at the TU Delft under Leo Kouwenhoven . As a post-doctoral student he was with David Awschalom at the University of California, Santa Barbara . He then led his own research group at the TU Delft, where he became Antoni van Leeuwenhoek Professor in 2012 . He is a senior scientist and one of the four founding professors (2013) at QuTech (Quantum computing and quantum internet) at the TU Delft.

He deals with quantum information theory and the quantum internet and technical use of quantum entanglement . In particular, he is researching the fundamentals of a future quantum internet with a pilot project between different cities in the Netherlands.

In 2015 he and his group published a loophole-free test of Bell's inequality . With two different photons each, they entangled two electrons over a distance of 1.3 km. In previous experiments, either photons were entangled (many of which were lost before detection) or ions that were not far enough away.

In 2013/14 he and his group succeeded in quantum teleportation between electrons on different chips.

In 2018 he and his group succeeded in creating quantum entanglement between two chips faster than it was lost. Using methods similar to those in their 2015 experiment, they were able to specifically generate 40 quantum entanglements per second, a thousand times more than previously possible.

For 2019 he received the Spinoza Prize . He also received the John Stewart Bell Prize in 2017 (with Anton Zeilinger and Sae Woo Nam ) for the loophole-free test of the Bell inequality, the Huibregtsen Award in 2016, the KNAW Ammodo Prize in 2015 and the Nicholas Kurti Prize in 2012. In 2018 he became a member of the Koninklijke Hollandsche Maatschappij der Wetenschappen (KHMW) and in 2019 of the Royal Netherlands Academy of Sciences (KNAW).
