A Blurry Magnetic Map Hid 2,178 Tiny Spins—Physics Helped Find Them
An AI-and-physics team reconstructed 2,178 hidden nanomagnet spins from blurry sensor maps by combining machine learning with physical constraints.

Could a tiny vapor cell make dark matter flicker in laser light?
A proposed chip-scale atomic sensor could turn a hidden-photon dark-matter signal into a faint, readable flicker of laser light.
The Quantum Searchlight That Finds a Signal Without Scanning
A superconducting cavity uses Grover’s search to identify an unknown signal frequency, but scaling the quantum sensor remains difficult.
