U.S. Army Seeking Quantum-assured Position, Navigation, Timing… But… 
A recent report on U.S. Army modernization has been released by the U.S. Government Accountability Office.  The preponderance of technologies listed are near-term; now through 2026.  However, quantum-assured PNT is not in the near-term.  It rears its head circa 2050.  Yep.  2050.  This is suggestive of the current status of quantum at DARPA.  The quantum technology for quantum-assured PNT  is “not quite within reach, but…it will be available within a little more than 30 years…”
