In quantum computing, it's not just the computers themselves that are hard to build. They also need sophisticated quantum algorithms--specialized software that's tailored to get the best out of the machines. Alán Aspuru-Guzik has gained an impressive reputation in academic circles by developing these kinds of algorithms, and now he's taking them to a wider market. A Harvard University professor (who's moving to the University of Toronto) and a 2010 member of MIT Technology Review's Innovators under 35 list, he is the cofounder of a company called Zapata Computing, which launched today with $5.4 million in announced funding. Zapata's ultimate goal is to be a kind of quantum-algorithm superstore, offering a broad range of ready-made software that companies can use to tap the immense processing power quantum computers promise to deliver.
