A microchip device precisely controls laser light while consuming far less power, making large-scale quantum computers feasible. Produced using standard CMOS fabrication, it enables mass production of photonic devices, allowing thousands of qubits to be controlled efficiently. This innovation paves the way for scalable, integrated quantum computing and advanced photon...

A red giant star orbiting a quiet black hole spins faster than expected, while internal vibrations reveal it is younger than its ancient chemistry suggests. These findings hint at a past stellar merger and challenge existing models of star evolution in low-metal environments. Future observations aim to confirm its complex cosmic history.
