Physicists model vacuum tunneling in a 2D superfluid

Credit: CC0 Public Domain In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron pairs would be spontaneously created out of nothing, through…

Probability theorem gets quantum makeover after 250 years

What would Thomas Bayes think? In 1763, he proposed a new approach to calculate probabilities. An international team has now updated his ideas to deliver a quantum Bayes’ rule. Credit:…
