The three elements of quantum fluctuations, nonlinearity and time-delayed feedback work together in this experiment to produce a virtually inexhaustible store of random numbers at the highest ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...

Gravity can exist without mass.” It’s a statement that upends a century of astrophysical dogma and, for some, sounds as ...

We propose and demonstrate a scheme to realize a high-efficiency truly quantum random number generator (RNG) at room temperature. Using an effective extractor with simple time bin encoding method, the ...

Quantum clocks break energy limits, unlocking ultra-precise timekeeping with far-reaching tech, AI, and navigation impacts.

While randomising a deck of cards gets more difficult as you add more cards, it turns out that the same isn't true for the ...

Understanding randomness is crucial in many fields. From computer science and engineering to cryptography and weather ...

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

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

While randomising a deck of cards gets more difficult as you add more cards, it turns out that the same isn't true for the qubits of quantum computers, which may prove surprisingly useful ...
