Physicists just built a quantum lie detector. It works

An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum correlations that can’t be explained classically. Their results show quantum computers are not just bigger, but more authentically quantum. This opens the door to more secure communication and stronger quantum algorithms.

Scientists accidentally create a tiny “rainbow chip” that could supercharge the internet

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 laser light, the team achieved lab-grade precision on a small silicon device. This could drastically improve data center efficiency and fuel innovations in sensing, quantum tech, and LiDAR.
