Quantum cryptography is absolutely unbreakable, as it relies on the laws of physics to rat out eavesdroppers. But like other encryption methods, it is sometimes only as good as the users and their hardware.
A group at the Norwegian University of Science and Technology and Germany's University of Erlangen-Nürnberg, together with the Max Planck Institute for the Science of Light, found a vulnerable point in quantum cryptography systems.
Gregoire Ribordy, CEO of ID Quantique, a Swiss company that builds equipment used in quantum encryption systems, says the trick is avoiding the laws of quantum mechanics. "Quantum encryption's only assumption is that the laws of quantum physics apply," he said. In situations where the laws don't apply, the code can be broken.
Quantum cryptography doesn't actually encrypt a signal by itself - but it is a way to send decryption keys in a secure way. In its simplest form, it is just sending single photons down a fiber optic cable to a detector, at very low power.
