Automation of Nuclear Chemistry Processes Leads to
The Science Astatine-211 (At-211) is one of a handful of promising alpha emitting radioisotopes for cancer therapy. Its short 7.2-hour half-life means that it must be handled quickly to minimize losses due…
Quantum walk computing unlocks new potential in quantum science and technology
Quantum walk applications are divided into 4 main categories: quantum computing, quantum simulation, quantum information processing, and graph-theoretic applications. Credit: Xiaogang Qiang, Shixin Ma and Haijing Song Quantum walks are…
Most precise measurement of electrically neutral beauty meson lifetime achieved
A comparison of the new ATLAS result for the B0 lifetime with the previous ATLAS result, as well as results from the LHCb, CMS, D0, CDF, Belle II, BaBar and…
Where’s my qubit? Scientists develop technique to detect atom loss
