Quantum control: the experimental setup used to generate tunable random numbers from vacuum fluctuations. (Courtesy: Charles Roques-Carmes, Yannick Salamin) A new technique for exploiting the random ...

Recent work has focused on quantum-mechanical random-number generators that generate bits based on whether or not a photon is detected 7,8,9.Such systems are appealing both because the randomness ...

Physics Ultra-fast random number generator uses quantum fluctuations. Variations driven by pairs of particles and antiparticles that form and then annihilate can be used to generate random numbers ...

However, in the quantum world, even this "empty" space experiences fluctuations or changes. Imagine a calm sea that suddenly gets waves - that's similar to what happens in a vacuum at the quantum ...

In a supercooled lab setting, a tiny crystal has quietly flipped a half-century-old assumption on its head. Scientists at ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, ...

Very little in this life is truly random. A coin flip is influenced by the flipper’s force, its surrounding airflow, and gravity. Similar variables dictate rolling a pair of dice or shuffling a deck ...

Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations—virtual photons popping in and out of existence that can interact with matter, giving rise to new, ...

This results in random and violent fluctuations in spacetime that are larger than envisaged under quantum theory, rendering the apparent weight of objects unpredictable if measured precisely enough.

“In both quantum gravity and classical gravity, spacetime must be undergoing violent and random fluctuations all around us, but on a scale which we haven’t yet been able to detect,” said ...

They were looking to see whether these ultra-high-energy particles were bothered by random quantum fluctuations in spacetime that would be expected if gravity were quantum mechanical, ...

So, while measurements of the quantum vacuum at any one point yield random energies that average to zero, those same quantum fluctuations are correlated with the fluctuations measured at any other ...
