A newly proposed protocol to boost privacy in quantum sensor networks
Schematic of a quantum sensor network. Unknown parameters are spatially distributed across the network. Metrologically, the objective is to estimate a function of these parameters, such as their average value.…
Quantum-inspired advancement turns crystal gaps into terabyte storage for classical memory
A crystal used in the study charges under UV light. The process created by the University of Chicago Pritzker School of Molecular Engineering Zhong Lab could be used with a…

Study nearly nixes negative gluon spin
Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red) after the addition…
Physicists find deformed nuclei when searching for ‘dark forces’
PTB’s ion traps (top right) and the PENTATRAP Penning trap mass spectrometer at MPIK in Heidelberg (bottom left) were used to obtain a new insight into the differences between isotopes…
Quantum computers successfully model particle scattering
When quantum mechanical particles scatter, it shifts the position of their wave. The new algorithm accurately measures these shifts, opening the way to quantum simulations of scattering processes. Credit: Sofia…
