**Quantum Key Distribution (QKD) System at 1310 nm**
The National Institute of Standards and Technology (NIST) has developed a QKD system that combines high speed and long distance capabilities. This system uses photons in the 1310-nm band to encode quantum keys, which are then used for secure communication.
**Key Features:**
– **Speed:** The system achieves approximately 500 Kbit/s of secure-key rates over 10 km and up to 200 Kbit/s for continuous encryption.
– **Distance:** Secure keys can be generated over long distances, with performance metrics showing successful key generation at both short (10 km) and medium-range (50 km).
– **Chromatic Dispersion:** The use of the 1310-nm wavelength minimizes chromatic dispersion in standard single-mode fibers, reducing noise during transmission.
**Impact on Quantum Technologies:**
This NIST QKD system demonstrates significant advancements in high-performance quantum key distribution systems. Its ability to achieve fast secure-key rates over extended distances makes it an attractive solution for various secure communication applications.
**Implementation Timeframe:**
While specific implementation timelines are not provided in this article, research into practical applications of this technology continues.
