Twin of NASA's Perseverance Mars rover begins terrain tests

On a recent day in November, the car-size rover rolled slowly forward, then stopped, perched on the threshold of a Martian landscape. But this rover, named OPTIMISM, wasn't on the Red Planet. And the landscape was a boulder-strewn ...

Machine learning contributes to better quantum error correction

Researchers from the RIKEN Center for Quantum Computing have used machine learning to perform error correction for quantum computers—a crucial step for making these devices practical—using an autonomous correction system ...

Simulations of polymers? A quantum puzzle

Using computers to study polymers has always been a major challenge for scientific computation, especially for long and densely packed biomolecules, like DNA. New perspectives are now opening up through quantum computing. ...

New study changes view on flying insects

For the first time, researchers are able to prove that there is an optimal speed for certain insects when they fly. At this speed, they are the most efficient and consume the least amount of energy. Corresponding phenomena ...

Google Chrome extensions to be officially released

(PhysOrg.com) -- Google is expected to release its Extensions Gallery for general users of the new Chrome browser this week, possibly at the Add-On Conference on browser extensions to be held on December 11, 2009. Google ...

D-Wave and predecessors: From simulated to quantum annealing

The D-Wave computer is currently the latest link of a long chain of computers designed for the solution of optimization problems. In what sense does it realize quantum computation? We describe the evolution of such computers ...
