Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

Quantum theory then tells us the probabilities to obtain different ... If you are investigating quantum systems that consist of very few particles (for example, a hydrogen atom with only a few ...

In simpler terms, the second law of thermodynamics means that things naturally tend to become more disordered over time.

New research shows that the second law of thermodynamics, which states entropy increases over time, also applies to closed ...

QuEra Computing said on Tuesday the neutral-atom quantum firm has completed a funding round in excess of $230 million, with ...

Entropy always increases, but in quantum systems, traditional entropy measures seem constant. TU Wien researchers resolved this paradox by considering Shannon entropy, which accounts for the ...

But according to quantum theory, entropy should actually stay the ... control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the ...

"Antimony is a heavy atom, which possesses a large nuclear ... fabricated and operated the quantum devices. Theory collaborators in the U.S., at Sandia National Laboratories and NASA Ames, and ...

The team from Australia has demonstrated that an atom of antimony can ... concerns with one interpretation of quantum mechanics—the then relatively new theory that explains how matter behaves ...

While the prevailing consensus has been that Einstein's theory of gravity must be modified to fit within the framework of quantum theory, a new theory, coined as a "postquantum theory of classical ...
