In an experiment described in Science, Chinese researchers used photons (also known as light particles) from the country’s quantum-communications satellite and established an instantaneous connection between two ground stations more than 744 miles apart. By doing so, say the experts, China is now a pioneer in harnessing matter and energy at a subatomic level — and a leader in the field of using quantum technology to build a global communications network that can’t be hacked. Meanwhile, the U.S. Department of Energy is paying for companies to develop new supercomputers in pursuit of at least one “exascale” system.
