A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of ...

Researchers are exploring multi-level atomic interactions to enhance quantum entanglement. Using metastable states in strontium, they demonstrate how photon exchange can sustain correlations, offering ...

Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum ...

Interactions between atoms and light rule the behavior of our physical world, but at the same time, can be extremely complex.

The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, ...

Scientists introduced atomic defects in spinel using cerium, and voilà! The gemstone became a solid qubit system.

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 mechanics 100 years on ... Rather than constructing an atomic model based on the idea that electrons move along well-defined orbits in a roughly classical fashion, Heisenberg decided ...

New Quantum Sensing Technology Reveals Sub-Atomic Signals Jan. 6 ... Dec. 17, 2024 — String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a ...
