NIST is developing quantum communication and networking technologies through research on quantum devices and network testbeds. Key areas of focus include:
1. Quantum repeaters and network systems:
– Single photon sources with narrow linewidth and specific wavelengths for efficient interaction with quantum memories
– Quantum memories using Electromagnetically Induced Transparency in Cesium atoms
– Quantum interfaces for wavelength conversion between different photon characteristics
2. Emerging technologies:
– Silicon carbide (SiC) for integrated quantum devices due to its compatibility with CMOS foundry and favorable properties
– Nonlinear optics for quantum network interconnects and frequency conversion
3. Quantum network testbeds:
– NIST Gaithersburg Quantum Network (NG-QNet) with various testbeds for quantum networking layers, control planes, and device/network performance
– DC-QNet consortium of six DC-area federal agencies building a regional quantum network testbed
4. Quantum network metrology:
– Developing metrology tools and methods to characterize quantum network devices and components
– Extending characterization to whole network links and entire networks for optimization and protocol development
5. Related projects:
– Nonlinear optics for quantum information and networking applications
– Research and development on quantum repeaters and supporting measurement technologies
NIST aims to bridge fundamental quantum research with practical information technology applications, promoting US innovation, industrial competitiveness, and national security.
