A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...

Quantum physics fundamentally redefines our understanding of nature by describing the behaviour of matter and energy at the smallest scales. Unlike classical theories, quantum mechanics reveals that ...

Tube trains of the future may soon know exactly where they are underground -- even in places where GPS is blind -- by tapping ...

The year isn't over yet, but we've already seen record-breaking quantum computers, skyrocketing levels of investment, and demonstrations of real-world benefits. In all the hype about AI it can be easy ...

Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical systems on some tasks. Instead of storing information as bits, ...

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...

For years, quantum computing sat at the far edge of most strategic roadmaps—important someday, but not urgent now. In 2025, that excuse is gone. Breakthroughs on four separate fronts—bigger and better ...
