Animation Study led by a University of Oregon physicist reconfigures a distance-calculation technique built around empirical observations. Using known distances of 50 galaxies from Earth to refine calculations in Hubble’s constant, a research team led by a University of Oregon astronomer estimates the age of the universe at 12.6 billion […]

PNNL quantum algorithm theorist and developer Nathan Wiebe is applying ideas from data science and gaming hacks to quantum computing. Everyone working on quantum computers knows the devices are error prone. The basic unit of quantum programming – the quantum gate – fails about once every hundred operations. And that error […]

Algorithm Quickly Simulates a Roll of Loaded Dice The fast and efficient generation of random numbers has long been an important challenge. For centuries, games of chance have relied on the roll of a die, the flip of a coin, or the shuffling of cards to bring some randomness into […]

A new MIT-developed search-and-rescue algorithm identifies hidden “traps” in ocean waters. The method may help quickly identify regions where objects — and missing people — may have converged.
