Simple Quantum Schemes Help Reduce Communication Flaws

Among the most active fields of research in modern physics, both at an academic level and beyond, are quantum computation and communication, which apply quantum phenomena such as superposition and entanglement to perform calculations, or to exchange information.

Cyclicity of Quantum Causal Models

Causal reasoning is ubiquitous - from physics to medicine, economics and social sciences, as well as in everyday life. Whenever we press the button, the bell rings, and we think that the pressing of the button causes the bell to ring. Normally, causal influence is assumed to only go one way - from cause to effect - and never back from the effect to the cause: the ringing of the bell does not cause the pressing of the button that triggered it.

New Study Detects Extreme Tidal Mass Loss in Dwarf Galaxies

A research team headed by astronomers from the University of California, Riverside, has discovered that certain dwarf galaxies might now appear dark-matter free although they formed as galaxies dominated by dark matter previously.

Research Findings Urge to Improve Present Nuclear Structure Models

In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in both experimental and theoretical nuclear physics from University of Jyväskylä, Finland, took part of international research team, which studied the nuclear charge radii of potassium isotopes. Isotopes were studied by using the collinear resonance ionization spectroscopy technique.

Researchers Discover a New Avenue to Search for Axions

Researchers from the international BASE collaboration at CERN, Switzerland, which is led by the RIKEN Fundamental Symmetries Laboratory, have discovered a new avenue to search for axions--a hypothetical particle that is one of the candidates of dark matter particles.

Machine Learning Model Provides Complete Quantum Description of the Solvated Electron

The behavior of the solvated electron e-aq has fundamental implications for electrochemistry, photochemistry, high-energy chemistry, as well as for biology--its nonequilibrium precursor is responsible for radiation damage to DNA--and it has understandably been the topic of experimental and theoretical investigation for more than 50 years.
