The global race to develop quantum technology is getting crowded. The study of quantum mechanics looks at how particles smaller than atoms interact with each other. And at this minuscule scale, entirely different laws of physics apply. Understanding and harnessing how these subatomic particles interact could lead to technological advancements as consequential as the transistor in fields like super-computing, encryption and even medical treatment. But in the global race to develop quantum technology, the United States is competing in an increasingly crowded field. NewsHour Weekend's Christopher Booker reports.
