Chinese Jin Class Nuclear Missile Submarine
Interesting to note The National Interest has had this article run previously.  Very little has been reported in the media since that time. Makes for an interesting read and makes one wonder how much further this military use of quantum technology will go. Because Quantum is Coming. Qubit

China’s Quantum Radar: How Submarines Become Obsolete?

+  Though still facing by range coherence limitations, quantum sensors and communicators could potentially bypass many of the limitations and vulnerabilities of traditional radio-frequency sensors, remaining effective despite jamming or stealthy-aircraft profiles.  As detailed in this article, China appears to have taken an early lead in ‘quantum radar’, though how soon the technology can be developed into an operationally viable system remains to be seen.

+  But on June 21, 2017, a Chinese periodical announced that Professor XIamong Xie of the Shanghai Institute of Microsystems and Information Technology had developed cryogenic liquid-nitrogen-cooled SQUID which reduced the noise-problem—and in field-tests, had proven capable of detecting ferrous objects deep underground even when mounted on a helicopter.

+  After a South China Morning Post article speculated on whether it amounted “to the world’s most powerful submarine detector?” the original article was taken down.

+  Professor Andre Luiten of the Institute for Photonics and Advanced Sensing is quoted thusly: “These magnetometers can detect very small magnetic fields. The goal of this project is to build sensors that go on the seabed which detect the presence of submarines through their properties. You’d essentially set up a trip wire around assets that are of importance to Australia.”
