Neutral-atom arrays, a rapidly emerging quantum computing platform, get a boost from researchers‎

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian Will and Nanfang Yu have their sights set much higher.

An innovative new tool draws on emojis to improve consumer sentiment analysis‎

Black Ivory coffee: Elephant gut bacteria may contribute to its smooth, chocolaty flavor‎

Coffee beans that pass through the digestive tracts of animals get their unique flavors from the activity of gut microbes, report researchers from the Institute of Science Tokyo. The guts of Asian elephants that produce Black Ivory coffee (BIC) were rich in pectin-digesting bacteria. Heat-driven degradation of pectin during roasting makes coffee bitter. Bacterial activity that reduces the pectin content of BIC could be the source of its smoother, chocolaty, and less bitter flavor.
