Fast-forwarding quantum calculations skips past the time limits imposed by decoherence, which plagues today’s machines. A new algorithm that fastforwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.

“Quantum computers have a limited time to perform calculations before their useful quantum nature, which we call coherence, breaks down,” said Andrew Sornborger of the Computer, Computational, and Statistical Sciences division at Los Alamos National Laboratory, and senior author on a paper announcing the research...

Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our sun.

A study led by Washington State University scientist Dirk Schulze-Makuch recently published in the journal Astrobiology details characteristics of potential “superhabitable” planets, that include those that are older, a little la...

A strong, black coffee to wake you up after a bad night’s sleep could impair control of blood sugar levels, according to a new study.

Research from the Centre for Nutrition, Exercise & Metabolism at the University of Bath (UK) looked at the effect of broken sleep and morning coffee across a range of different metabolic markers.

Writing in the British Journal of Nutrition the scientists show that whilst one night of poor sleep has limited impact on our metabolism, drinking coffee as a way to perk you up from a slumber can have a negative effect on blood glucose (sugar) control.

Given the importance of keeping our blood sugar levels within a safe ra...
