The Space-Based Quantum Cryptography Race | MIT Technology Review.
Europe and China are gaining the upper hand in the race to bounce perfectly secure messages off satellites in low Earth orbit.
One of the great benefits of quantum communication is the ability to send messages from one point in space to another with perfect security. Not so great is the fact that so-called quantum cryptography is limited to distances of around 100 kilometers.
Last year, the Chinese announced plans to launch a spacecraft in 2016, called the Chinese Quantum Science Satellite. specifically designed to test these concepts. And European scientists have proposed a quantum communications experiment that could be sent to the international space station.
U.S. plans are much less clear. That may be because the work is being done behind closed doors. On the other hand, the U.S. may be dragging its feet.
Here is an oldie-but-goodie as we approach our nation’s 238th birthday anniversary. The first step in problem solving is to recognize that there is a problem. America is not the greatest country in the world anymore. The Declaration of Independence and the Constitution—written over 230 years ago— are two of the greatest contributions to the modern world, but the opportunity and freedom that fueled generations of Americans is sharply declining by most measures. The United Kingdom, Australia, Canada, Japan, and even Estonia (go ahead and find that on the map…I will wait) have more freedom and opportunity than America. Although we are 3rd in median household income, 4th in exports, and 7th in literacy, we are only 27th in math, 22nd in science, and 49th in life expectancy.
