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

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

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

Amid some scepticism, many say the machines can now achieve results beyond the capability of traditional computers ...

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states exist in ...

When it comes to understanding the universe, what we know is only a sliver of the whole picture.

You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

Scientists have used high-performance computing at large scales to analyze a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a ...

A quantum internet would essentially be unhackable. In the future, sensitive information—financial or national security data, for instance, as opposed to memes and cat pictures—would travel through ...

Scientists at Paderborn University have for the first time used high-performance computing (on the right in the picture the Paderborn supercomputer Noctua) to analyse a quantum photonics experiment on ...
