NIST is developing comprehensive metrology standards for quantum network components and systems to ensure compatibility and interoperability as quantum networks grow more complex. The standards cover key performance metrics for single-photon sources, detectors, and other network components, measured using advanced techniques like photon-number resolving detectors and tomography.
The work is part of a broader effort to establish a globally optimized quantum internet, with NIST collaborating across its operating units to develop the necessary characterization frameworks and reference standards. The ultimate goal is to enable heterogenous multi-mode quantum networks with advanced nonclassical metrology and monitoring capabilities.
Implementation timeframes are not specified, but the work is expected to accelerate the development of compatible quantum network systems and guide future network growth and optimization.
