A research team at Tohoku University’s Advanced Institute for Materials Research (WPI-AIMR) has developed a new technique to rapidly and accurately determine the charge state of electrons confined in semiconductor quantum dots—fundamental components of quantum computing systems. The method is based on Bayesian inference, a statistical framework that estimates the most likely state of a system using observed data. 

A mathematician has built an algebraic solution to an equation that was once believed impossible to solve. 

Human populations need at least 2.7 children per woman – a much higher fertility rate than previously believed – to reliably avoid long-term extinction, according to a new study published April 30, 2025 in the open-access journal PLOS One by Takuya Okabe of Shizuoka University, Japan, and colleagues.

Researchers at QuTech in Delft have combined superconductors and quantum dots to observe and manipulate so-called Majorana bound states, which have properties that could enable stable quantum computation. By building a chain of three coupled quantum dots in a two-dimensional electron gas, they were able to demonstrate properties of Majoranas that are essential for the study of Majorana-based quantum bits. The results were published in Nature this week.
