Physicists have now managed to track the passage of time inside a quantum event without using anything that looks like a traditional clock. Instead of ticking gears or oscillating crystals, they read ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Tue, December 23, 2025 at 1:00 PM UTC Because the goal is so lofty, tracking its progress has also been difficult. To help chart a course toward truly transformative quantum technology and mark ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...
