Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Lattice gauge theory provides a powerful framework for discretising gauge theories to explore the fundamental interactions that underlie particle physics and complex condensed matter phenomena. By ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

Ultracold atoms sit at the heart of the quantum-technology revolution. India has built a strong and steadily growing presence ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

(via Sabine Hossenfelder) Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most ...
