It is understood that the Max Planck Institute for Quantum Optics (MPL) team of experts at the recent success of the first single crystal rare earth ions precise positioning and accurate measurement of the energy state of its quantum mechanics. This study makes quantum information stored in the ion possible future development of quantum computers will have a significant contribution.

Worldwide, many scholars are studying the future to build a quantum computer module. Among them, the quantum system is a key element , quantum dots or light absorption defect ( color center ) is currently the focus of attention of many researchers . However, the light emitted by the rare earth ions are very small and difficult to detect . With precision laser and microscope technology experts after more than six years of in-depth study , yttrium silicate crystals in the trivalent praseodymium ions (Pr3 +) to pinpoint a few nanometers , and with unprecedented precision measuring its optical properties.

Scientists use a laser to excite ions in the single crystal , and observe how they after some time emit energy in the form of light again . Due to the rare earth ions by thermal and acoustic vibration crystals is not strong , some of its unusually stable energy state , you need more than a minute before returning to the ground state , which is more than most of today's studies of quantum systems millions of times a long time . Different information is stored in the quantum energy states of an atom or ion , praseodymium ion as a quantum computer memory .

Researchers future nano- micro resonator antenna and strengthening the Pr signal hundreds or thousands of times smaller than the single ion response 100 photons per second , then the ion signal can be seen more easily .

U.S. Department of Energy 's Ames Laboratory researchers found that in certain special circumstances like the rare earth magnetic iron can produce , but also provide raw materials for a new license and easier to obtain for generators and motors . The researchers said the discovery of high-strength permanent magnets used in hybrid car motors currently offers the possibility to produce magnetic iron and permanent. Hybrid car motors and permanent magnet electromagnet transformed into mechanical motion into electricity . Although iron can produce magnetic , but still want to REE into an industrial magnet , but the biggest challenge is the high price of rare earth ore and limited quantity , it is difficult to meet the demand . However , the lab's researchers said ferromagnetic of nitrogen can . But because the magnetic appears only at low temperatures , and therefore did not achieve a breakthrough in industrial production . This is just a basic scientific advances , technological breakthroughs for the future indicate a path . I hope this discovery will help in the automotive and high-tech alternative to the rare element used in industry . Source: China metal mesh

Today, the rare earth market prices of some products continue to shock down , continued sluggish demand , turnover deserted. Downstream products are praseodymium , neodymium , dysprosium, gadolinium , europium, terbium and so on. Which praseodymium neodymium downward slightly, but some businesses offer slightly down to mainstream price points .

Dysprosium products, businesses today continue to have lowered the dysprosium oxide and dysprosium iron prices , relative to the current market price of dysprosium oxide , there has been a significant decline last week , comprehensive business feedback dysprosium oxide prices now more concentrated in 1.6 million yuan / ton in the vicinity , there are some 158 million low- emergence of dysprosium iron prices dropped to around 1.65 million yuan / ton. Along with dysprosium , europium, gadolinium , terbium oxide as well as the decline of the offer, and now according to some traders said gadolinium oxide is now shipping prices around 14.5-15 yuan / ton, in order to obtain a small profit , only to find more low-cost sources. Held in the current weak demand , competitors and more rare earth industry , but also to prevent the risk of decline in prices, many traders had to look for ultra low supply everywhere , all aspects of the business profits are on the decline .

Europium, terbium oxide , increasing price trend down , the lowest volume small . Currently part of the business by now I know that europium , terbium oxide shipments difficult , and occasionally received purchase inquiries, lower prices more serious. Europium, terbium oxide poor demand , vendors think the price outlook or further downstream. Currently comprehensive market feedback, europium oxide prices to 3700-3800 yuan / kg , terbium oxide with votes at around 3000-3050 yuan / kg , so the price is slightly lower than last week 50-100 yuan / kg.

Mexico will begin to explore the projects funded positioned on the rare earth metals, rare earth metals have applications in a wide variety , such as green technology , defense systems, consumer electronics and high-tech industries such as increasingly important .

According to the National Geological Survey (SGM) , the global demand for rare earths in 2016 will reach 160,000 tons , of which China is expected to produce 80 %, which leaves room for other suppliers ,

Meanwhile , the latest release by the National Academy of Sciences and the European Union 's research has issued a warning to the world , saying that some of the key elements in the future may soon face a serious shortage . Currently about 95 % of the world's most advanced rare earth from Asia, China , and the country needs to export quotas . Currently , except China , only two rare earth mine in production . One of them is the Australian company to the NC , Lynas CorpM, another American molybdenum company (Molycorp).

Mexico is one of the world's most advanced 10 largest crude oil producer , ambitious government last year proposed a reform plan. This is designed to open the country's energy sector program for more than seven decades . They also seek to use cheap energy to promote local industry

State mining company directly employs approximately 334,000 employees , 200 million are indirectly employed , is in addition to the oil , automotive and electronics fourth largest foreign exchange earner .

Although the number of rare earth deposits in Mexico is not yet clear, but the country 's deep in the West Bank , there are such elements. Deep-sea mining, although unlikely to replace mined land , but still can ease fears of a shortage of rare earth and to challenge China 's rare earth monopoly.
