Proposal for Implementing Device-Independent Quantum Key Distribution Based on a Heralded Qubit Amplifier
Proposal for Implementing Device-Independent Quantum Key Distribution Based on a Heralded Qubit Amplifier
In device-independent quantum key distribution (DIQKD), the violation of a Bell inequality is exploited to establish a shared key that is secure independently of the internal workings of the QKD devices. An experimental implementation of DIQKD, however, is still awaited, since hitherto all optical Bell tests are subject to the …
