Palo Alto, Calif.-headquartered D-Wave will pay US$300 million worth of its own shares and US$250 million in cash for New Haven, Conn.-based Quantum Circuits. (The Logic)

Talking point: Founded in Burnaby, B.C., in 1999, D-Wave is one of several firms trying to develop useful quantum computers. The company has historically used an approach called quantum annealing, which it claims is closer to solving real-world problems than other methods, but which may have limited application. In recent years, it expanded into more popular gate-based systems, which are the focus of Quantum Circuits, spun out of Yale University in 2015. D-Wave claims the deal gives it significant strength in both techniques for building quantum computers, and captures more of the market for the machines’ problem-solving capabilities. It also expands the firm’s U.S. footprint—it is folding the Quantum Circuits team into a new R&D centre in New Haven. D-Wave’s stock traded flat on the Nasdaq Wednesday.
