We demonstrate for the first time a positive secure-key rate at 2.1 µm (0.417 bits/pair, with a quantum bit error rate of 5.43%), using near-maximally entangled photons in a proof-of-principle device-independent quantum-key-distribution scenario.

Abstract
We demonstrate for the first time a positive secure-key rate at 2.1 µm (0.417 bits/pair, with a quantum bit error rate of 5.43%), using near-maximally entangled photons in a proof-of-principle device-independent quantum-key-distribution scenario.
