Quantum teleportation with nonlinear sum frequency generation (SFG). The nonlinear nanophotonic platform greatly mitigates multiphoton noise and leads to high teleportation fidelity. Researchers have ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

A standard digital camera used in a car for stuff like emergency braking has a perceptual latency of a hair above 20 milliseconds. That’s just the time needed for a camera to transform the photons ...

Author Dr. R. Russell Rhinehart discusses his new book, Nonlinear Model-Based Control: Using First-Principles Models in Process Control, and explains why nonlinear first-principles models should be ...
