Winfried K. Hensinger

from Wikipedia, the free encyclopedia

Winfried K. Hensinger is a German physicist who studies quantum computer technology.

Hensinger studied at the Ruprecht-Karls-Universität Heidelberg , where he took his intermediate diploma examination, and at the University of Queensland in Brisbane , where he obtained his master’s degree and did his doctorate with Halina Rubinsztein-Dunlop, Norman Heckenberg and Gerard Milburn . At that time he was concerned with nonlinear quantum dynamics with ultracold atoms and, during a stay at the National Institute of Standards and Technology, demonstrated dynamic quantum tunneling ( i.e. tunneling between two states of motion) in Bose-Einstein condensates with sodium atoms with Nobel Prize winner William Daniel Phillips in Gaithersburg . As a post-doctoral student , he spent three years with Christopher Monroe at the University of Michigan , where a collaboration began to create large numbers of ion traps for single atoms on microchips using chip manufacturing technologies (US patent granted in 2008). He continued this at the University of Sussex , where he moved in 2005 as a lecturer , became a professor and heads the Quantum Technology Group.

In 2015, at the University of Sussex, he succeeded in developing a method of cooling atoms in ion traps with microwaves (instead of the usual laser) to a millionth of a degree above absolute zero.

In 2017 he and his group presented the blueprint for a quantum computer.

He also deals with educational issues (in Brisbane he also received a Graduate Certificate in Education and developed a new beginner course in physics).
