Device-Independent Quantum Key Distribution protocols aim at establishing a secret key between two honest parties whose security is independent of the details of the devices used in the protocol. In this work, the authors propose an implementation of this idea using a noiseless photon amplifier. The proposal suggest that positive secret-key rates may be obtained using near-future technology.
