Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a single photon can carry. This leap could make quantum communication more ...

Quantum dot (QD) lasers enable intrinsically feedback-tolerant, isolator-free silicon photonic integrated circuits (PICs), eliminating the bulky optical isolators traditionally required to suppress ...

Ever since humans began building, they’ve been building up. Throughout the millennia, our constructions have reached higher and higher into the sky, spurred by various motivations: religion, democracy ...
