Substantial research has shown that while reading, we recognize words by their letters and not by the general shape of the word. However, it was largely unknown how we differentiate one letter from another.

Quantum Cryptography – Latest Technology To Protect Information

Quantum Cryptography - Latest Technology To Protect Information 

Quantum cryptography seems to be the latest technology that might help in protecting people’s information. The technique depends on Heisenberg’s uncertainty principle, which states that it is impossible to measure at the subatomic level without altering it. So, when a QC system sends a message in 0 and 1 format, and if someone tries to eavesdrop, the message structure changes and the recipient can detect the tampering. The message, which is sent in the form of a photon beam, doesn’t encode the message but only contains the key for the actual message, and the recipient later uses the key, which is shared by the sender to encode the message.
