Intel Corp. /zigman2/quotes/203649727/composite INTC -1.08% unveiled a chip Monday meant to speed the development of commercially viable quantum computers. Code named "Horse Ridge," the cryogenic control chip is meant to control multiple quantum bits, or qubits, which must be maintained at a few degrees above absolute zero. Unlike traditional bits, which take on a value of either "0" or "1," qubits are considered to be able to exist in multiple states simultaneously in a superimposed quantum state, allowing for more complex calculations. So far, quantum computing has been demonstrated in experimental conditions. "While there has been a lot of emphasis on the qubits themselves, the ability to control many qubits at the same time had been a challenge for the industry," said Jim Clarke, director of quantum hardware at Intel. "Intel recognized that quantum controls were an essential piece of the puzzle we needed to solve in order to develop a large-scale commercial quantum system. That's why we are investing in quantum error correction and controls. With Horse Ridge, Intel has developed a scalable control system that will allow us to significantly speed up testing and realize the potential of quantum computing."
