"Light lasers and single photons are part of the field photonics, but soundwaves fall under the umbrella of phononics, or the study of phonons," Deymier said.  Now, researchers at Stevens Institute of Technology have coaxed photons into interacting with one another with unprecedented efficiency-a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing.  An international team of researchers, affiliated with UNIST has presented a core technology for quantum photonic devices used in quantum information processing. They have proposed combining of quantum dots for generating light and silicon photonic technologies for manipulating light on a single device.  Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator.  Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control.  Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers.  Considerable interest in new single-photon detector technologies has been scaling in this past decade.  Engineers develop key mathematical formula for driving quantum experiments.  Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers.
