Research by the national institute of information and communications technology in Japan, including senior visiting researcher Tobias a. Eriksson, is expected to address one of the main challenges of the application: how to achieve secure communication using continuously variable quantum key distribution.
This method, usually abbreviated as QKD, is the continuous exchange of encryption keys generated by quantum technology, which is used to encrypt data transmitted between two or more parties.

In a paper to be presented March 3, solstice, 7 at OFC: fiber optic communications conference and exhibition in San Diego, California, riksson and his colleagues say the main obstacle to this application is the noise produced by fiber optic amplifiers.
Generation single mode optical fiber system.
Their research involves exploring the use of multi-core optical fiber technology that is expected to be used in future transmission networks.
As the name suggests, a multicore fiber optic system USES multiple fiber cores in a single strand through which data can be transmitted.
In today’s fiber-optic networks, each line usually has only one core.
“Secure communication is one of the most difficult challenges, and many current encryption methods could one day be easily broken by algorithms designed specifically for quantum computers,” erickson said.
“One reason we haven’t seen a commercial deployment of QKD is that the technology is not compatible with the current network architecture.”

Eriksson says researchers are studying how to use the technology to solve encryption problems as multicore fibers are deployed in the future.
“The question we asked ourselves was whether the spatial dimensions of the multi-core fiber could be used for the co-propagation of classical and quantum signals,” erickson said.
“We found that classical channels can completely ignore quantum signals, because amplifier noise kills quantum channels, so that’s not possible in single-mode fiber.”
Eriksson’s team used a 19-core optical fiber to measure excess noise in crosstalk between classical and quantum channels.
They found that it was possible to support 341 QKD channels with wavelengths of 1,537 nm and 1,563 nm spaced at 5 GHz.

The team’s work is outlined in a paper to be presented at the OFC conference in San Diego.
When quantum channels use dedicated cores of multi-core optical fibers, network operators can avoid core-to-core crosstalk noise between classic channels carrying data by ensuring that the wavelength of quantum signals from QKD is in the protection band, the team reports.
This simple solution solves the multiplexing problem of quantum and classical channels and avoids introducing new components for classical communication channels.

Since the reform and opening up, China’s hardware and electrical industry has developed rapidly.
Although the domestic hardware and electrical industry has achieved certain development results, but if viewed from the global environment, the proportion of China’s hardware and electrical industry in the world, and China as a major hardware and electrical production status is not suitable.

Every economy developed country, its hardware mechanical and electrical industry is developed inevitably.
Throughout the country, all economically developed provinces and cities, its hardware industry is also developed.
Hardware industry is a traditional industry involving People’s Daily life.
At the same time, the hardware and electrical industry is the basic industry of other industries, so it is the pillar industry of the national economy.

China’s gap is not only reflected in the brand, but also in the size of enterprises.
None of the top 10 Chinese companies in this year’s world machinery 500 are included, and only nine Chinese companies are in the top 100.
The threshold for China’s top 500 machinery companies is $0.3 billion, while the threshold for the world’s top 500 machinery companies is $2 billion.
In this year’s world machinery 500, the United States tops the list with 126 households, Japan tops 124, and China tops 77.
This series of data is worth considering deeply.

Our country hardware mechanical and electrical tools industry in the world status of continuous improvement, gradually become the world hardware processing power and export power, hardware industry at present presents a new development trend, mainly reflected in the following aspects.

Technology investment improves the quality, market competition will be based on price to high quality, high technology content of products.
With the deepening of competition, the profit space of each stage of hardware industry chain is being compressed, and the space of price reduction is decreasing day by day.
More and more enterprises realize that price competition alone cannot establish core competitiveness and is not the direction of long-term development, so they try to explore new development paths.
Integration with foreign enterprises will constantly improve the quality of Chinese hardware products and enterprise competitiveness.

The requirements of the international market for China’s hardware products will gradually develop and change, and there will be higher requirements on the quality, packaging and delivery period of Chinese products, and even gradually extend to the production process and product research and development, combining products with environmental protection, energy resources and cultural environment.
Many hardware enterprises increase the technical investment, develop new products with high technology content, take product differentiation as the long-term solution of enterprise development, seek new market demand, establish new economic growth point, in order to achieve sustainable development of enterprises.

Hardware mechanical and electrical tools demand year by year, hardware product quality improvement, capital expansion intensifies, enterprise cooperation in the increase and other trend characteristics for the strength of large hardware enterprises, it is really good, when this kind of large enterprises comply with the development trend, will only gradually become stronger and bigger.
For hardware enterprises, product quality may exist gap, cooperation opportunities are relatively less, let alone capital operation.
Therefore, in the continuous development and progress of the hardware industry, the survival environment of small enterprises will be more difficult.
Matthew effect refers to the phenomenon that the strong get stronger and the weak get weaker.
For the hardware industry, enterprises with strength use hardware trend to better analyze the development of enterprises, and for small and medium-sized enterprises, only stubborn transformation and upgrading, in order to spell out a world in the hardware industry.

Distribution: zhejiang and guangdong are most prominent

China’s hardware tools market is mainly distributed in zhejiang, jiangsu, Shanghai, guangdong and shandong, among which zhejiang and guangdong are the most prominent.
Zhejiang yongkang has always been known as the “hometown of hardware”, and zhejiang people’s market operation consciousness is quite strong, from the original hot pot products, stainless steel thermos cups to last year’s popular scooter, brought them a lot of money.
Guangdong will soon become the world’s mold production center.

At present, there are more than 6000 mould enterprises around shenzhen and the pearl river delta region, employing more than 100,000 people.
The south China international mould exhibition has been held in shenzhen for five consecutive years, which has attracted more than 1000 enterprises from 25 countries and regions to participate in.

status: outward – oriented development

Since the early 1990 s, China’s hardware industry has always maintained a rapid development, has now become important metal products production country in the world, but there is no denying the fact that China’s hardware industry in product research and development, innovation, brand management, marketing management, enterprise scale, financial strength, and many other aspects there exists a large gap between the hardware industry in the world.
Performance in the market share, our country in the international trade total share of the proportion is very low, and hardware production status is not commensurate.
Investigate its reason is our country hardware product still is in the primary state of low class, low price.
This gap on the one hand to the development of the hardware industry to bring heavy resistance, but also let us see a huge market potential, as long as the technical content of their own improvement, China’s hardware products do big and strong road is still wide.

With the acceleration of China’s integration into the global economic environment and the rapid rise of its economic power, China has become the most dynamic economic region in the world.
With relatively complete economic facilities, relatively mature industrial development and low labor costs, China has the comparative advantage of becoming a global hardware manufacturing center. The export-oriented development of hardware manufacturing industry has obvious characteristics.

The strengthening of the central position is firstly reflected in the overall growth of hardware products export in recent years. The export growth rate of major hardware products is higher than the growth rate of production, and higher than the growth rate of domestic market sales.
Main hardware electric equipment product blossoms in the round, not only power tools, hand tools, building hardware products these traditional export category product growth rate is very high, and before the export proportion is not big hutch electric products and sanitary ware products 2004 export growth rate is also very obvious.
The huge market and central gravity will further attract multinational hardware manufacturing centers to China.

Demand: growing market size

In recent years, with the explosion of China’s real estate market, the real estate industry has experienced an unpredicted rapid growth.
Hardware industry is pushed ceaselessly in estate army mature.
Our country hardware industry gross output value is higher than the home appliance industry, and with the annual growth rate of 20% high-speed development.
And with the improvement of people’s living standards, brand hardware entered the home of ordinary people, especially with hardware brand door locks and other products demand is particularly strong.

Thanks to the economic stimulus plan, the domestic economy and international trade as well as the real estate industry, the demand for a large number of hardware parts is booming and the scale is expanding rapidly.
In recent seven years, the sales revenue of China’s metal products industry has been increasing year by year, with the growth rate remaining above 14% and the market scale expanding continuously.
And our country hardware manufacturing industry will reach international advanced level as a whole.
Every year, China exports more than 10 billion us dollars of hardware products. With the improvement of the economic environment and the enhancement of the overall competitiveness of domestic hardware enterprises, this figure is still growing and the development potential of the hardware industry is huge, among which the market capacity of individual categories such as door locks and handle handles is around 100 billion yuan.
And with the government’s plan to stimulate domestic demand, the hardware market growth prospects will be very broad.
