ETH Zurich researchers built a “perfect die” by entangling two qubits across a 30-meter link and refining the output with a two-source extractor to produce randomness whose unpredictability is certified by quantum physics, with potential applications in cryptography, gaming, and secure computing, showcasing quantum advantage over classical generators.
ETH Zurich researchers used a Bell-test experiment with entangled qubits separated by 30 meters and performed over a billion trials in about nine hours to demonstrate randomness amplification that transforms imperfect randomness into certifiably perfect randomness, a device-independent result that could underpin future cryptography and security systems. The work, published in Nature 2026, shows randomness that remains truly unpredictable under rigorous analysis, surpassing previous RNGs that depended on trusted hardware.
Researchers demonstrate device-independent randomness amplification by performing a loophole-free Bell test on superconducting circuits, achieving high Bell violation and a fast trial rate to convert weak, imperfect randomness into high-quality randomness—an outcome impossible to achieve classically. The work includes publicly available data and code from ETH Zurich and advances quantum randomness generation with implications for cryptography and quantum information processing.
MIT researchers have achieved a breakthrough in quantum technologies by controlling quantum randomness using "vacuum fluctuations." This milestone opens up possibilities for probabilistic computing and ultra-precise field sensing. By injecting a weak laser "bias" into an optical parametric oscillator, the researchers were able to create controllable quantum randomness, allowing for the manipulation of probability distributions. This development has implications for simulating complex dynamics and optimizing systems that involve uncertainty and randomness.
