Trapped Ions Go the Distance
Researchers have achieved long-distance entanglement between two calcium ions, each of which lies in a different building, showing that trapped ions could be used to create quantum networks. Read More »
Optical Fibers Go Topological
A new design for an optical fiber borrows concepts from topology to protect light from imperfections in the fiber’s light-guiding materials or from distortions in its cross section. Read More »
Tracking Isotopes in the Upper Atmosphere
The first measurements of a heavy oxygen isotope in Earth’s upper atmosphere suggest that isotopic concentrations could become powerful probes of atmospheric processes at otherwise hard-to-probe altitudes. Read More »
Cosmological Parameters Improved by Combining Data
Using cross-correlation measurements and an updated cosmic-microwave-background lensing map, researchers determine cosmological parameters with greater precision. Read More »
The Uneven Spread of Citations
Minority physicists are significantly undercited compared to their white, male counterparts, which can have serious career consequences. A new tool is allowing researchers to reduce this imbalance. Read More »
Probing Majorana Neutrinos
Detecting neutrinoless double-beta decay would confirm that the neutrino is its own antiparticle. Data from the KamLAND-Zen experiment contain no strong evidence of such events, constraining neutrino properties. Read More »
Memories Become Chaotic before They Are Forgotten
A model for information storage in the brain reveals how memories decay with age. Read More »
The Unimportance of Accurate Financial Knowledge
Simulations of the behavior of individual financial traders show that imperfect market knowledge increases risk but not overall losses. Read More »
Quantum Circuit Tackles “Diabolical” Photochemical Process
A quantum device shows promise for simulating molecular dynamics in a difficult-to-model photochemical process that is relevant to vision. Read More »
