Lecture no. 20 from the course: Quantum Mechanics

Quantum Cryptography

Taught by Professor Benjamin Schumacher | 31 min | Categories: The Great Courses Plus Online Science Course

The uncopyability of quantum information raises the possibility of quantum cryptography—an absolutely secure method for transmitting a coded message. This lecture tells how to do it, noting that a handful of banks and government agencies already use quantum cryptography to ensure the security of their most secret data.
