The end of stealth? New Chinese radar capable of detecting ‘invisible’ targets 100km away
A top Chinese military technology company shocked physicists around the world this week when it announced it had developed a new form of radar able to detect stealth planes 100km away.

The breakthrough relies on a ghostly phenomenon known as quantum entanglement, which Albert Einstein dubbed "spooky action at a distance".

China Electronics Technology Group Corporation (CETC), one of the "Top 10" military industry groups controlled directly by the central government, said on Sunday that the new radar system's entangled photons had detected targets 100km away in a recent field test.

That's five times the "potential range" of a laboratory prototype jointly developed by researchers from

last year.

America's Defence Advanced Research Projects Agency has reportedly funded similar research and military suppliers such as

are also developing quantum radar systems for combat purposes, according to media reports, but the progress of those military projects remains unknown.

In a statement posted on its website on Sunday, CETC said

's first "single-photon quantum radar system" had "important military application values" because it used entangled photons to identify objects "invisible" to conventional radar systems.

Nanjing University physicist Professor Ma Xiaosong, who has studied quantum radar, said he had "not seen anything like this in an open report".

"The effective range reported by the international research community falls far below 100km," he said.

A military radar researcher at a university in northwestern China said the actual range of the new radar could be even greater than that announced by CETC.

"The figure in declassified documents is usually a tuned-down version of the real [performance]," he said. "The announcement has gone viral [in the radar research community]."

The scientists said they were shocked because, until recently, the idea of quantum radar had remained largely confined to science fiction.

Quantum physics says that if you create a pair of entangled photons by splitting the original photon with a crystal, a change to one entangled photon will immediately affect its twin, regardless of the distance between them.

A quantum radar, generating a large number of entangled photon pairs and shooting one twin into the air, would be capable of receiving critical information about a target, including its shape, location, speed, temperature and even the chemical composition of its paint, from returning photons.

That sounds similar to a normal radar, which uses radio waves, but quantum radar would be much better at detecting stealth planes, which use special coating materials and body designs to reduce the radio waves they deflect, making them indistinguishable from the background environment.

In theory, a quantum radar could detect a target's composition, heading and speed even if managed to retrieve just one returning photon. It would be able to fish out the returning photon from the background noise because the link the photon shared with its twin would facilitate identification.

However, Ma, who was not involved with the CETC project, said serious technical challenges had long confined quantum radar technology to the laboratory.

The photons had to maintain certain conditions – known as quantum states – such as upward or downward spin to remain entangled. But Ma said the quantum states could be lost due to disturbances in the environment, a phenomenon known as "decoherence", which increased the risk of entanglement loss as the photons travelled through the air, thus limiting the effective range of quantum radar.

The CETC breakthrough benefited largely from the recent rapid development of single-photon detectors, which allowed researchers to capture returning photons with a high degree of efficiency.

CETC said the quantum radar's advantage was not limited to the detection of stealth planes.

The field test had opened a "completely new area of research", it said, with potential for the development of highly mobile and sensitive radar systems able to survive the most challenging combat engagements.

Quantum radar systems could be small and would be able to evade enemy countermeasures such anti-radar missiles because the ghostly quantum entanglement could not be traced, it said.

The company said it had worked with quantum scientists at the University of Science and Technology of China in Hefei, Anhui province, where many quantum technology breakthroughs have been achieved, including the world's longest quantum key distribution network for secured communication and the development of the world's first quantum satellite.

One detail that I think worth to clarify is "100km". The CETC article says "百公里级探测威力" which is "hundred-kilometer class detection capability". That means anything from 90km to 190km, just like Y-20 being called in China "200-tone class" which is 220 tone max. CETC did not say anything like "100km or around 100km". So stuck "100km" in our mind could lead to a misleading impression that is far below the real range. But I won't brag 199km either.

Yeah but the stealth detection radar program is just getting started and as research and development progresses the range and effective will improve as well. Remember, It's all about the program.;)

A high ranking official of AVIC involving a espionage case. The rumor suggested that the person has been arrested. Someone please translate the following story:

近日,一则极具震撼性的消息,在中航工业的干部职工中悄然流传:中航工业科技委副主任、总装备部先进制造技术专家组组长、原中航工业制造所所长郭恩明突然失联。

据不同渠道消息来源称,郭恩明多日前失联,疑渉间谍案,已被国安部门带走审讯调查。

郭恩明是单独犯案,还是另有同伙,会不会牵出中航工业、总装备部系统的窝案,值得观察。

郭恩明的职务是“中航工业科技委副主任“,同时也是总装备部先进制造技术专家组组长,除了知悉中航工业系统内部大量隐秘资料,也常年接触大量国防武器装备军工机蜜资料,如果传言成真,对于国家的安全和利益,造成难以估量的巨大危害。

郭恩明受聘北京理工大学

老郭突然失联,在中航工业和国防科技工业投下了震撼弹,也给人们留下了难以解开的谜团,以正面形象示人的郭恩明,为什么会涉足谍海,走上不归路,是被人下药被动失足?还是没能逃过漂亮“女间谍“的致命诱惑?还是仇视社会主义,仇视航空工业,自甘堕落与国家与人民为敌?。

航空版《潜伏》正在火热上演,将令认识熟悉他的人们目瞪口呆、瞠目结舌。这是一个活生生的军工版斯诺登,将令全世界哗然!

中航工业多年来的国家秘蜜,将不复存在,敌特敌对势力如获至宝。

为国护盘,保卫五星红旗将成为梦幻泡影,成为又一个大笑话,成为绝妙的讽刺

, who allegedly talked to a lot of in-the-know people and gathered a bunch of news.

1. Su-35s will be arriving in China soon.

2. Russians were uncharacteristically cooperative, opening up the Su-35's FCS port. Presumably this would allow the PLAAF to easily integrate Chinese ordnance with the Su-35.

3. The PLAAF is interested in the Su-34.

4. Russia has developed an Su-34 variant, called Su-34MK, for China. They hope China will sign the contract during the reception ceremony of the first four Su-35s.

5. Russia has proposed multiple configurations of the Su-34MK, some of which include AL-41F or high-thrust variants of the AL-31F. The Su-34MK, if materialised, has double the range of Su-30MKKs and rivals the Badgers in that regard.

6. Russia wishes for China to share composite material technology and China wishes for Russia to share "一体锻造". Could someone, @vincent maybe, translate the last bit? It has multiple interpretations and I'm not sure which one fits this context most appropriately.

7. Russia has recently become much more willing to export advanced hardware, perhaps a desire to offset the impacts of sanctions and rock bottom oil prices. Even sale of Tu-160 is negotiable. However, China is not very interested in solely importing systems, she prefers "technological cooperation" endeavours.

8. Negotiations for the Backfires had indeed occurred. However, due to its technological obsolescence, China called off negotiations.

If these allegations are true, I think we should definitely re-evaluate the recent and near-future Sino-Russo military relationship. Even with sanctions and low oil price, I don't think anyone expects Russia to be so open with military engagement. This increase in openness could explain why China decided to purchase Su-35s all of a sudden, despite not showing interest for close to a decade. Of course, all this is conditional upon the Su-35 purchase and above points' actually being true.
