美国防部网站3月9日讯

在美国国防工业协会8日举行的太平洋作战科技研讨视频会议上，围绕量子科学、5G和定向能专题，国防部隶属研究与工程副部长办公室的一些技术官员发表了看法。在量子科学方面，首席主任保罗·洛帕塔称，国防部开展量子科学研究已经历了二三十年，尽管距离形成实际应用能力还十分遥远，但在四个领域产生了重要影响。第一，也是最重要的影响，是原子钟，主要应用于GPS。第二，各种类型的量子传感器，主要应用于陀螺仪、加速度计、磁力计和重力传感器等。第三是量子计算，第四是量子通信与网络。后两种目前还处于基础研究阶段，未来将最终形成能力并实现应用。

DOD Officials Discuss Quantum Science, 5G and Directed Energy

MARCH 9, 2021 | BY DAVID VERGUN, DOD NEWS

Three of the Defense Department’s 11 principal directors of modernization within the Office of Defense Research and Engineering, discussed quantum science, 5G and directed energy.

The three are responsible for informing senior DOD leaders about science and technology investments that will provide warfighters the greatest return on investment.

They spoke yesterday at the National Defense Industrial Association’s virtual Pacific Operational Science and Technology Conference.

Paul Lopata, principal director for quantum science, said the DOD has been doing quantum science research for the last 20 or 30 years.

Although quantum science is often thought of as a distant future capability, it is actually having an impact on DOD operations today in four areas, he said.

The first and probably most important, he said, are atomic clocks. The department has historically used high-performance timekeeping for such things as position, navigation and timing, and GPS.

The enemy is aware of the advantage GPS gives to the department so they have developed techniques like spoofing and jamming to disrupt the DOD’s time synchronization and the ability to incorporate signals from sensors. Spoofing and jamming also disrupts the department’s ability to encrypt communications, Lopata said.

To respond to that threat, the department is developing higher performance atomic clocks, he said.

The second category, he said, is made up of quantum sensors of different types, used for gyros, accelerometers, magnetometers and gravitational sensors, all of which are used for position, navigation and timing. Research is being done to improve quantum sensors as well.

Quantum computing is the third category, Lopata said. That’s a future development that will enable computers to attain extraordinarily high performance.

The fourth category uses quantum science for communications networks, he said. That capability will also mature further down the road.

Although quantum science for computing and networks is not yet fully developed, a lot of good basic research is being done in those categories to ensure that those capabilities will eventually yield results.
