Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Abstract The phenomenon of Bose-Einstein condensation of dilute gases in traps is
reviewed from a theoretical perspective. Mean-field theory provides a framework to …

Engineered quantum systems enabling novel capabilities for computation and sensing have
blossomed in the last decade. Architectures benefiting from combining complementary …

In the field of quantum simulation, methods and tools are explored for simulating the
dynamics of a quantum system of interest with another system that is easier to control and …

Single trapped ions represent elementary quantum systems that are well isolated from the
environment. They can be brought nearly to rest by laser cooling, and both their internal …

The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

The superposition principle plays the most central role in all considerations of quantum
information, and in most of the" gedanken" experiments and even the paradoxes of quantum …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …
