Quantum harmonic oscillator state synthesis by reservoir engineering

Abstract

Engineering a shelter for quantum protection In isolation, quantum states of matter can be stable entities. These states are often seen as useful when they can be made to interact in a controlled way. However, those interactions and the unavoidable interactions with their environment often correlate with decoherence and eventual loss of the quantum state. Kienzler et al. show that they can engineer the interactions between a quantum system (a trapped ion) and the environment to prepare stable quantum states. The generality of the technique implies applications for other interacting quantum systems. Science , this issue p. 53
