The near-field tip-antenna enhanced signal transduction with femtosecond laser pulses allows for spatio-spectral and spatio-temporal imaging and quantum coherent control with the perspective to reach the single electronic or vibrational quantum level.
Quantum teleportation  is a cornerstone of quantum information science due to its essential role in several important tasks such as the long-distance transmission of quantum information using quantum repeaters [2–4]. In this context, a challenge of paramount importance is the distribution of entanglement between remote nodes, and to use this entanglement as a resource for long-distance light-to-matter...
Terahertz radiation permits resonant and sensitive probing of electron transport, spin precession and ion vibration in solids. Recently developed sources of strong-field terahertz pulses even allow one to gain control over these fundamental modes.
Challenges for building a quantum repeater system using a nitrogen vacancy center in diamond are overviewed and the futures are discussed. Our approach for further development of quantum repeater network is also presented with experimental demonstrations of quantum entanglement detection between a photon and an electron spin in an NV center for quantum entanglement swapping.

Lasers are an indispensable tool for current XUV and X-ray free electron light sources and are key to future laser driven accelerator technology. We discuss the role of fiber-laser technology in this emerging field.
Entanglement plays a central role in fundamental tests of quantum mechanics as well as in the burgeoning field of quantum information processing. Particularly in the context of quantum networks and communication, an outstanding challenge is the efficient generation of entanglement between stationary (spin) and flying (photon) qubits.
