Probability theorem gets quantum makeover after 250 years

An international team of researchers has derived a quantum Bayes' rule from a fundamental principle, providing a breakthrough in mathematical physics. The discovery has potential applications in quantum computing for tasks such as error correction and machine learning.

How experience may lead to misperception

A new study by neuroscientists at the Bernstein Center Munich found that previous experience plays a significant role in shaping our perceptions of physical quantities. The researchers developed a Bayesian model that integrates two classic theories and explains how prior knowledge affects judgment, leading to systematic estimation biases.
