Researchers at Columbia have created a chip that turns a single laser into a “frequency comb,” producing dozens of powerful light channels at once. Using a special locking mechanism to clean messy ...

Penn engineers have taken quantum networking from the lab to Verizon’s live fiber network, using a silicon “Q-chip” that speaks the same Internet Protocol as the modern web. The system pairs classical ...

A team of engineers has made major strides in generating the tiniest earthquakes imaginable. The team’s device, known as a surface acoustic wave phonon laser, could one day help scientists make more ...
