China’s drive to dominate a field with big economic and military applications outpaces some U.S. strides
HANGHAI — More than a decade ago, Chinese physicist Pan Jian-Wei returned home from Europe to help oversee research into some of the most important technology of the 21st century.
At a conference in Shanghai this summer, Pan and his team offered a rare peek at the work he described as a “revolution.”
They spoke of the hacking-resistant communications networks they are building across China, the sensors they are designing to see through smog and around corners, and the prototype computers that may someday smash the computational power of any existing machine.
All the gear is based on quantum technology — an emerging field that could transform information processing and confer big economic and national-security advantages to countries that dominate it. To the dismay of some scientists and officials in the United States, China’s formidable investment is helping it catch up with Western research in the field and, in a few areas, pull ahead.
