The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

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 ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She calculated that collisions involving three different types of subatomic ...

Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them ...

For bringing quantum effects to a scale once thought impossible, three physicists have won the 2025 Nobel Prize in physics. In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated the ...

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics. John Clarke, ...

In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.
