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 ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

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 ...

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 ...

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 ...

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

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.

Fluctuations are temporary random changes in the thermodynamic state of a material that is on the verge of undergoing a phase transition. ... “The direct detection of these moving vortices gives us an ...

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 ...

“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 ...
