Quantum key distribution without detector vulnerabilities using optically seeded lasers
Open accessAbstract
Quantum cryptography immune from detector attacks is realized by the development of a source of indistinguishable laser pulses based on optically seeded gain-switched lasers. Key rates exceeding 1 Mb s−1 are demonstrated in the finite-size regime. Security in quantum cryptography1,2 is continuously challenged by inventive attacks3,4,5,6,7 targeting the real components of a cryptographic set-up, and duly restored by new countermeasures8,9,10 to foil them. Owing to their high sensitivity and complex design, detectors are the most frequently attacked components. It was recently shown that two-photon interference11 from independent light sources can be used to remove any vulnerability from detectors12,13. This new form of detection-safe quantum key distribution (QKD), termed measurement-device-independent13 (MDI), has been experimentally demonstrated13,14,15,16,17,18,19 but with modest key rates. Here, we introduce a new pulsed laser seeding technique to obtain high-visibility interference from gain-switched lasers and thereby perform MDI-QKD with unprecedented key rates in excess of 1 megabit per second in the finite-size regime. This represents a two to six orders of magnitude improvement over existing implementations and supports the new scheme as a practical resource for secure quantum communications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
