Quantum cryptography, the most secure method of transmitting data, has taken a step closer to mainstream viability with a technique that simplifies the distribution of keys.

Researchers at the National Institute of Standards and Technology claim that the new "quantum key distribution" method minimises the required number of detectors, the most costly components in quantum cryptography. What is your opinion on the state of computer cryptography. I am glad to see researching working on improving the security of cryptography.
