Daniel Loss (born February 25, 1958 in Winterthur ) is a Swiss physicist and professor of theoretical solid-state physics at the University of Basel .

Life

Loss studied medicine at the University of Zurich from 1977 to 1979 before moving to physics at the same university in 1979, where he graduated in theoretical physics in 1983 with Norbert Straumann in relativity theory and in 1985 with Armin Thellung in statistical physics. He was then a research assistant to Nobel Prize winner Sir Anthony James Leggett and conducted research at the University of Illinois in Urbana (Illinois) . This was followed by work at the IBM Thomas J. Watson Research Center , before Loss moved to Simon Fraser University in Vancouver as Assistant Professor in 1993 and Associate Professor from 1995 . Since 1996 he has been a full professor for theoretical physics at the University of Basel. From 1998/99 and from 2008 to 2010 he headed the physics faculty.

Loss works on theoretical solid state physics, semiconductor nanostructures and spintronics and is considered one of the pioneers in the field of quantum computers . In addition, he dealt with magnetic molecules and nanomagnetism, among other things. For example, generation and characterization of quantum entanglement with quantum dots, Luttinger fluids or Coulomb scattering in two-dimensional electron gases, spintronics in two-dimensional electron gases, spin-Hall effect in disordered systems, spin currents in magnetic insulators and semiconductors, spin-orbit effects in Transport and noise, spin coherence and tunneling in nanomagnetism, transfer of quantum entanglement from electron spins to photons and the Majorana fermion in solid state physics.

In 1997, together with David DiVincenzo from the Thomas J. Watson Research Center at IBM , he proposed the Loss DiVincenzo quantum computer , which uses electron spins in quantum dots as qubits . Leo Kouwenhoven and many other experimental groups around the world worked on realizations of this type and spin qubits . Loss is further investigating various related phenomena such as spin relaxation and decoherence in quantum dots due to spin-orbit and hyperfine interactions. He also studies quantum informatics with molecular magnets.

Loss has published more than 260 specialist publications and is one of the most cited physicists worldwide. Loss is director of the Center for Quantum Computing and Quantum Coherence (QC2) in Basel, founded in 2005, and has also been co-director of the Swiss National Center of Competence and Research (NCCR) in Nanoscale Science at the University of Basel since 2006 .
