Naturally Occurring Radiation Limits Superconducting Qubit Coherence Times
Two new experiments have demonstrated the correlation between natural radiation levels and the duration of qubit coherence. If radiation cannot be mitigated, it will limit the coherence time of qubits to a few milliseconds.

Probing the “Equation of State” of Neutron Matter—The Stuff that Neutron Stars Are Made Of
To predict the properties of matter in a neutron star, physicists consider a theoretical model that consists of an infinite system of pure neutrons that interact by the strong nuclear force. This allows them to calculate the neutron matter equation...

A Pioneering Exploration of Exotic Nuclei
The nuclei of some isotopes with a specific number of protons and neutrons are more tightly bound than isotopes with more or fewer protons or neutrons. Scientists have now gained a new understanding of the nucleus of mercury-207, an isotope with...

An Innovation for Fusion Device Walls May Have Unexpected Benefits for the Core
Instabilities in tokamak confinement fields can damage reactor walls by exposing them to plasma. Resonant magnetic perturbation (RMP) suppresses instabilities, but it was thought to impair confinement. New research shows that RMP has no effect on...
