DESCRIPTION:Speaker: Sungkun Hong\nhosted by Johannes Fink\nAbstract: Inter
 facing a single photon with various quantum degrees of freedom is an outst
 anding problem in quantum information science. It allows for long-distance
  quantum communication and entanglement distribution between distant quant
 um systems such as spin states of atoms\, atomic ensembles or solid-state 
 qubits. Recently\, micro-fabricated optomechanical devices have been consi
 dered as a new type of optical quantum interfaces for quantum networks. Th
 ey utilize versatility of mechanical degrees of freedom which can coherent
 ly couple to a variety of physical systems. This then allows for transduci
 ng quantum information between optical photons and other stationary quantu
 m systems by means of mechanical motions.\nIn this talk\, I will present o
 ur experimental works on realizing on-chip optical quantum interfaces base
 d on optomechanical devices. We utilize nanofabricated silicon photonic an
 d phononic crystals as our on-chip optomechanical devices. With these stru
 ctures\, we demonstrated the generation of quantum correlated pairs of sin
 gle (optical) photons and single (mechanical) phonons\, which is the first
  step towards photon-phonon quantum interface. Based on this work\, I will
  discuss the implementation of a protocol for generating entanglement betw
 een two remote optomechanical devices.
