The document summarizes the 2020 White House strategic vision for developing quantum networks in the United States. It outlines two goals: (1) over the next five years, demonstrate the foundational science and technologies to enable quantum networks; and (2) over the next twenty years, quantum internet links will leverage networked quantum devices to enable new capabilities. It recommends pursuing research in six specific technical areas to advance quantum networking, including quantum interconnects, quantum repeaters, and entanglement distribution. The National Quantum Coordination Office was established to coordinate quantum information science research across the US government to ensure American leadership in this area.
