The realization of a highly connected network of qubit registers is a central challenge for quantum information processing and long-distance quantum communication. Diamond spins associated with NV centers are promising…
Quantum information processing promises to speed up certain computational tasks. The expectations are high, but many technological hurdles have to be overcome before we can build a quantum computer. Nevertheless,…
…interacting systems is also at the frontier of current research. Important open problems include kinetic theory of quark-gluon plasma, charge and energy transport in biological macromolecules. Ultracold Bose and Fermi…
The dark matter puzzle is one of the most important open problems in modern physics. I will describe some of the approaches that are used to search for non-gravitational interactions…
…a physical system that unambiguously displays supersolidity has not been found thus far, and the mere existence of free-space supersolidity in any type of quantum solid remains an open question….
