Quantum Cryptography Passes Another Critical Test
On a clear night last September, at a little Ontario airport, two pilots, two scientists, and an engineer took off in a small plane. “One to a hundred of them.” The point of this high-altitude game was to test a technology known as quantum cryptography. But it's hard to pull off; quantum cryptography requires precise control of individual photons over a long distance. It works Quantum cryptography is so powerful because it's physically impossible for a hacker to steal a key encoded using quantum particles. "You can guarantee security between the White House and the Pentagon, or from the corner of one military base to another," says Caleb Christensen, the chief scientist at MagiQ Technologies, a Boston-area company that makes commercial quantum cryptography systems.
