Galaxy formation simulated without dark matter

For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified ...

First-ever calculation performed on optical quantum computer chip

(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed ...

Quantum chemistry on quantum computers

Quantum computing and quantum information processing technology have attracted attention in recently emerging fields. Among many important and fundamental issues in science, solving the Schroedinger equation (SE) of atoms ...

Densest dice packing and computing with molecules

Physicists have made two new breakthroughs -- discovering a shape that packs more efficiently than any other known, and completing a high speed quantum calculation thousands of times faster than possible with conventional ...

A zero sum game

(PhysOrg.com) -- New light has been shed on the 150-year-old math puzzle known as the Riemann hypothesis, say mathematical physicists at the University of Sydney.
