What to know about Quantum Physics

Researchers at ETH Zurich have developed a method called 'randomness amplification' using quantum physics to create perfectly random numbers. The technique utilizes superconducting chips and quantum entanglement to eliminate systematic errors found in traditional random number generators, with potential applications in cryptography and digital security.

What happened

Perfect randomness realized for the first time Gaby Clark Scientific Editor Robert Egan Associate Editor Creating perfect randomness is surprisingly difficult.

Why it matters

Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently than others.

Common ground

In cryptography, however, even the tiniest deviations can be problematic.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.

Loaded Language 60% confidence

Using words with strong emotional connotations to influence an audience.

Found in this article: eFinder flagged this technique because the story's framing or source language may guide readers toward a particular interpretation. Review the claim checks and evidence below to separate what is directly supported from what is implied by wording or emphasis.

Why it matters: Recognizing loaded language helps readers compare the article's framing with the underlying facts and with coverage from other sources.

Claim 1: “Anatoly Kulikov, Experimental randomness amplification, Nature (2026). DOI: 10.1038/s41586-026-10521-8.”

DISPUTED

The evidence provided for 'Anatoly Kulikov' refers to a Ukrainian powerlifter/YouTuber and unrelated Wikipedia pages. There is no evidence of a scientist named Anatoly Kulikov publishing this specific paper in Nature; the previous claims attribute the research to Renner and Wallraff.
