What if we are merely part of an experiment by an advanced civilization? To the Editor: Re “Are We Living in a Computer Simulation?,” by Preston Greene (Sunday Review, Aug. 11): Let me get this ...

The hope for quantum computers is that the devices will be able to solve complex tasks such as predicting how chemicals react or cracking encrypted text. One of the main reasons that the machines are ...

FORT BENNING, Ga. – It was another hot day about a year ago here when an Army team that runs battlefield experiments using computer simulation took seats at a long brown conference table and got ...

Physicists have spent decades arguing over whether our universe is a fundamental reality or a kind of cosmic software, and the debate has just taken a sharp turn. A group of researchers now say they ...

Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow ...

Team from U.S. Department of Energy-funded Quantum Science Center demonstrates quantum computers can perform material simulation that many previously believed to be beyond current quantum capabilities ...
