Immunizing quantum computers against errors

Building a quantum computer requires reckoning with errors—in more than one sense. Quantum bits, or "qubits," which can take on the logical values zero and one simultaneously, and thus carry out calculations faster, are ...

Yeast produce low-cost, high-quality cannabinoids

University of California, Berkeley, synthetic biologists have engineered brewer's yeast to produce marijuana's main ingredients—mind-altering THC and non-psychoactive CBD—as well as novel cannabinoids not found in the ...

Engineers make clear droplets produce iridescent colors

Engineers at MIT and Penn State University have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes.

Researchers create a 'universal entangler' for new quantum tech

One of the key concepts in quantum physics is entanglement, in which two or more quantum systems become so inextricably linked that their collective state can't be determined by observing each element individually. Now Yale ...

New material holds promise for more secure computing

As computers advance, encryption methods currently used to keep everything from financial transactions to military secrets secure might soon be useless, technology experts warn. Reporting today in the journal Nature, a team ...
