For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope revealed Jupiter’s moons and shook the geocentric universe. Thomas Young’s ...

The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

Quantum communication and measurement techniques constitute a rapidly evolving field that exploits the principles of quantum mechanics to enhance data transmission, security, and signal detection.

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes ...

A table top experiment typical of the setup. The size is more or less equal to the size of an ordinary dining table. Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a ...
