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.

The Federal Communications Commission will now allow new 4G LTE wireless devices (known as LTE-U, for unlicensed) to use a portion of unlicensed 5Ghz airwaves currently used for Wi-Fi. With this decision, wireless providers can now deliver mobile broadband service, sharing the airwaves with Wi-Fi, says new FCC chair Ajit Pai, who made the ruling as a way of ending the dispute between the two industries. In the wake of this decision, Verizon Communications and T-Mobile US announced they will launch LTE-U networks and devices in the spring.
