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

Researchers have confirmed the existence of a "nuclear-spin dark state," which could lead to more stable and powerful quantum ...

Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

the quantum-mechanical hydrogen atom is stable. If the hydrogen atom obeyed the laws of classical mechanics, by contrast, the electron would spiral into the proton in a tiny fraction of a second ...

If you are investigating quantum systems that consist of very few particles (for example, a hydrogen atom with only a few electrons), then such considerations are irrelevant. But today, especially ...

We've mentioned fuel cell manufacturer Quantum a few times recently in conjunction with their hydrogen storage systems being selected by General Motors for the fleet of fuel cell powered Equinoxes ...

Quantum researchers have long believed that strong spin interactions in qubits required covalent bonds, making large-scale ...

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 ...

Quantum Fuel Systems Technologies Worldwide, Inc. are providing the hydrogen fuel injectors used in the HICE E450s which will be included in the Senate shuttle bus fleet for evaluation.
