Or, as the\u00a0Center for a New American Security&#8217;s\u00a0senior fellow and director of the Technology and National Security Program,\u00a0Ben FitzGerald, put it, &#8220;The word &#8216;theoretical&#8217; comes up everywhere with quantum computing.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But while much of the capability is hypothetical, the US cannot afford to ignore the growth of quantum capabilities. According to Dahm, America accounts for about a quarter of the total global-declared R&#038;D in quantum technologies. Coming in second, he noted, is China, which means the US isn&#8217;t just looking for advantages, but defenses against quantum-enabled weaponry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">FitzGerald said quantum technology falls right in &#8220;the sweet spot&#8221; for the Pentagon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;It&#8217;s theoretical, it&#8217;s complex, it potentially solves a number of challenges the DoD already has without requiring any major institutional reform,&#8221; FitzGerald said. &#8220;It helps the department deal with issues around encryption and also to deal with data.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">FitzGerald said quantum is part of the &#8220;next\u00a0generation of next-generation technologies,&#8221; which could have an impact on defense far down the line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Or as Mark Gunzinger, a senior fellow with\u00a0the Center for Strategic and Budgetary Assessments, put\u00a0it:\u00a0&#8220;Quantum computing may be the next step toward maintaining the US military&#8217;s ability to assess and react to tactical situations far more quickly than its enemies.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Findings<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The three areas the SAB found had utility for the Air Force were quantum sensing, quantum communications\u00a0and quantum computing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For sensing, the potential for quantum navigation systems to replace inertial measurement units could deliver very high accuracy while not being jammed, giving pilots precise position information even if GPS is being blocked by an enemy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;These systems are making remarkable progress and could be brought to a level of maturity\u00a0in a relatively close time\u00a0scale,&#8221; Dahm said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Similarly, these sensors could give more accurate timing to weapons or other systems \u2014\u00a0if they can be shrunk down to fit onto a plane or bomb. The study recommends that the Air Force &#8220;take the lead&#8221; and invest in miniaturization of these systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But while some systems may be near-ready, that doesn&#8217;t mean they fit into the Air Force concept of operations. As an example, Dahm said that the oil and gas industry is\u00a0using quantum gravity gradiometers to search for areas with reservoirs of oil. That&#8217;s off-the-shelf technology available now \u2014\u2013 but it requires the plane to fly low to the ground, which is likely at odds with Air Force operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quantum communications are less fruitful, with the SAB concluding that the service should spend its money elsewhere.<\/p>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The high-level takeaway on the communication part is that most of what the studies saw in the quantum area, the Air Force has equally good or better alternatives with other approaches,&#8221; Dahm said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That includes things like quantum key distribution, which could enhance secure communications. But\u00a0&#8220;rather remarkably&#8221; the Air Force has other alternatives that are not as complex but provide roughly the same level of security, Dahm said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;That came as quite a surprise, certainly to me, but that&#8217;s why we do these [studies],&#8221; Dahm said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force, in particular, has struggled with what officials have called a &#8220;tsunami of data&#8221; that comes off various intelligence, surveillance and reconnaissance platforms. FitzGerald said that quantum computers could help in that regard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gunzinger added: &#8220;Quantum computing could revolutionize operations that require crunching large amounts of data very quickly.\u00a0It has obvious implications for validating the massive lines of code now needed to operate advanced weapon systems such as stealth fighters, for creating cyber operations time advantages over enemies\u00a0and conducting other operations which are extremely time sensitive.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seth Lloyd, a professor at the engineering systems division of the Massachusetts Institute of Technology who has studied quantum technologies, said data crunching is a great use of quantum computers. But a more exciting one, he said, is machines learning algorithms \u2014\u00a0which could eventually lead to automated data processing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;With quantum computers,\u00a0you can detect patterns in\u00a0a way you can&#8217;t&#8221; with older systems, Lloyd said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But while the imagination is focused on the hardware side, Dahm said, the trick is designing the algorithms that would allow software to operate on high-end future computers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;It&#8217;s the software side where things are weak, and unless the software matures much further, it is unlikely the Air Force should be expecting great utility from quantum computing,&#8221; Dahm said. Instead, he noted, the &#8220;study recommends a modest, continued effort, with a shift in focus more to the algorithm side than the hardware side.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Given the level of investment in quantum computing from industry \u2014 Canadian firm D-Wave, which claims to have the first fully operational quantum computer, counts both the US government and Lockheed Martin among its customer base \u2014 FitzGerald sees &#8220;some merit to the approach that says we should focus on algorithms rather than computing, from a purely market dynamics perspective.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lloyd also said that companies such as Google, Microsoft and IBM are pumping millions of dollars into quantum technology development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SAB is now turning its gaze to its next project list, which is expected to be announced in the coming weeks. The three completed studies are being briefed at the Pentagon, with final reports due by the end of summer for a January released.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Email: <a
