1 Apr 2015 | | Abstract: | An extensively pursued current direction of research in physics aims at the
development of practical technologies that exploit the effects of quantum
mechanics. As part of this ongoing effort, devices for information processing,
secure communication and high-precision sensing are being implemented with
diverse systems, ranging from photons, atoms and spins to mesoscopic
superconducting and nanomechanical structures. Their physical properties make
some of these systems better suited than others for specific tasks; thus,
photons are well suited for transmitting quantum information, weakly
interacting spins can serve as long-lived quantum memories, and superconducting
elements can rapidly process information encoded in their quantum states. A
central goal of the envisaged quantum technologies is to develop devices that
can simultaneously perform several of these tasks, namely, reliably store,
process, and transmit quantum information. Hybrid quantum systems composed of
different physical components with complementary functionalities may provide
precisely such multi-tasking capabilities. This article reviews some of the
driving theoretical ideas and first experimental realizations of hybrid quantum
systems and the opportunities and the challenges they present and offers a
glance at the near- and long-term perspectives of this fascinating and rapidly
expanding field. | | Source: | arXiv, 1504.0158 | | Services: | Forum | Review | PDF | Favorites | |
