Device-Independent Quantum Cryptography

Caption

The key to proving the security of device-independent quantum cryptography in a regime that is attainable with state-of-the-art quantum technology is the realization that any attack strategy, no matter how complex (symbolized in the lower row), can be decomposed into a sequence of simple steps (upper row).
