Laser light now extends atomic spin coherence 10x, boosting the performance and stability of next-gen quantum memory and ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing ...

A groundbreaking step in AI hardware efficiency comes from Germany, where scientists have engineered a vast spin waveguide network that processes information with far less energy. These spin waves — ...

If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated ...

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

In this paper, we propose a novel polarization beam splitter (PBS) based on a 3-waveguide directional coupler (DC) with a Si3N4-loaded horizonal slot waveguide as the bridge. The performance of the ...

To achieve intra-chip three-dimensional (3-D) integration of silicon photonic circuits, we design a polarization beam splitter based on complementary metal-oxide-semiconductor (CMOS) platform. With ...
