Daniel Loss (born 25 February 1958) is a Swiss theoretical physicist. He is best known for proposing, with David DiVincenzo at IBM Research, the Loss–DiVincenzo quantum computer in 1997,[1] which would use electron spins in quantum dots as qubits.

Life and career

[edit]

Daniel Loss was born on 25 February 1958 in Winterthur, Switzerland.[2] He studied medicine at the University of Zurich for two years before transferring to physics. In 1985, he obtained his PhD in physics from the University of Zurich with a thesis on statistical mechanics under the supervision of Armin Thellung. After postdoctoral stays in Zurich and at the University of Illinois in Urbana, where he worked with Anthony Leggett, he worked as a research scientist at the IBM T. J. Watson Research Center in Yorktown Heights. In 1993 he became professor at the Simon Fraser University in Vancouver, Canada, and since 1996 he is full professor at the University of Basel. He is also a professor of Theoretical Condensed Matter Physics at the King Fahd University of Petroleum and Minerals and Riken.

Loss's research concerns the quantum theory of condensed matter and solid-state physics. In particular, he studies spin and charge effects in semiconducting and magnetic nanostructures. He is one of the leading theorists investigating the realization of quantum information processing protocols in semiconductor structures. His 1998 paper, co-authored with David DiVincenzo, proposing the use of spin qubits in semiconductor quantum dots is the foundation of one of the main approaches towards the realization of a quantum computer and (as of 2025) has been cited more than 9,000 times.[3] Further lines of research include decoherence, nuclear spin physics, magnon physics, topological matter, Majorana fermions and parafermions.
