Quantum interfaces capable of transferring quantum states and generating entanglement between fields and matter are set to play a growing role in the development of science and technology. Development of such interfaces has been a crucial component in quantum information processing and communication. In the past decade quantum interfaces between atoms and optical photons have been extensively explored by a number of leading groups. Quantum state transfer between light and atoms, such as quantum memory and quantum teleportation, entanglement of massive objects, as well as measurements and sensing beyond standard quantum limits have been demonstrated by the group of the PI.We propose to develop a robust, integrated and scalable atom-light interface and to incorporate it into a hybrid multi-facet quantum network with other relevant quantum systems, such as nano-mechanical oscillators and electronic circuits.Towards this ambitious goal we will develop room temperature atomic quantum memories in spin protecting micro-cells (mu-cells) and opto-mechanical and electromechanical strongly coupled systems. Interfacing atoms, electronic circuits and nano-mechanical oscillators we will perform ultrasensitive quantum limited field and force measurements and quantum teleportation of states across the range of these systems.In the fundamental sense, this research program will further broaden the horizons of quantum physics and quantum information processing by expanding it into new and unexplored macroscopic domains.
