Chinese scientists have increased the storage time of light to 1 hour, what does it mean to retain l

The lost love can't be kept, time can't be kept, youth can't be kept, and light is something that can't be touched or kept. And how did a Chinese scientist manage to keep light for an hour? The team of academician Guo Guangcan of the University of Science and Technology of China used scientific principles to successfully "seal" the light in a special crystal, and the light that was released an hour later was still "alive".

This scientific study has already set a new one-minute record set by the German team in 2013. It is truly incredible to be able to preserve natural light that is out of reach of humans, and the practical value of this technological invention has not yet been revealed.

Technological research is a way for humans to communicate with nature.

Humans are capable of making televisions, computers, and mobile phones; It is possible to make various styles and different seasons of clothing; You can also cook a variety of cuisines. However, in the face of the amazing nature, human beings are still very small, and human beings cannot change nature. Even if human beings extract some material elements and process them to form some other material forms, they have also brought a lot of benefits to human life through scientific research, but human beings are still very powerless in the face of the majesty of nature, and scientific research is just a way for human beings to understand and communicate with nature.

Protecting nature is an unshirkable responsibility of human beings.

Nature is the mother of all human beings, and everyone depends on oxygen, water, and food in nature for survival. Because of the sun, human beings will go from sunrise to sunset and rest in a regular way, so that the body can function healthily and continue to rest and work. Human beings can dabble in some material things from nature to make their lives better.

However, if the damage to nature by humans is severe enough to a certain extent, the balance of nature will be disturbed, which will also lead to its own destruction.

Human beings rely on nature for survival, so maintaining the natural ecological balance and enabling the sustainable development of natural resources is the guarantee for the continuous development of human society.

This means that the light signal is broken down, stored in an object, and after an hour, it is re-exported and found to be in the same state.

Retaining light for 1 hour means using this advanced technology to increase the light storage time to 1 hour, which can be said to be a very great experiment.

It is to store light energy in a special crystal, and after an hour of release, it is still "alive", making a major breakthrough.

This is of great significance, which shows that our country can now store data in light for an hour, and then use light to transmit data, think about it, how far this can be transmitted.

It's a milestone in advancing the speed of storage, making science more popular, and kudos to them.

Discover new carriers, collect a speed of light propagation, conduct ** and observations, study some techniques, provide good results, facilitate a data search later, provide new scientific research results, and so on.

Being able to retain light for a long time is actually a kind of new energy storage and utilization, which can also allow human beings to use the sun's energy more efficiently. The light and heat on the earth are mainly the sun, but the sun is selfless and emits light and heat all the time, so the vast majority of light and heat are wasted in the universe.

In order to make efficient use of the sun's energy, scientists have put forward the hypothesis that by harvesting the sun's excess light and heat in the summer and releasing it in the winter, humans can greatly reduce the use of fossil fuels and keep them warm in the winter.

1. Light is also an energy source, which can be stored and can be used on a large scale

The light in our daily life mainly relies on the sun during the day and electricity at night, but electricity consumes a lot of fossil fuel resources, and nuclear power plants have not been widely used, so light at night is actually a very luxurious energy source.

If humans can store light for a long time, then they can collect a lot of light during the day, and if they can store light for 12 hours, they can basically say goodbye to artificial light at night, and street lamps collect light during the day and release light at night; Every home can capture light during the day and enjoy natural light at night, except for rainy days when artificial light may be needed.

2. The ability to collect light will become the premise of the "Dyson sphere":

According to scientists' speculation on cosmic civilization, if they enter the second-level civilization, advanced life should be able to use the "Dyson sphere" to collect all the energy released by stars.

To put it simply, just like wrapping the sun with solar photovoltaic panels, all the light and heat can be used as human energy, and at this time human beings will enter a period of abundant energy, and even interstellar travel. The premise of this is that human beings need to master the ability to collect and store light, and gradually convert the sun's light and heat into other energy sources.

As the world pays more and more attention to environmental protection, fossil fuels need to be phased out, and it is imperative to find renewable energy, and the closest energy reservoir to the earth is the sun.

If human beings can fully harvest the energy of the sun and convert it into the energy we need, then almost all of the earth's energy problems can be solved, and the earth's environment will become better and better. Solving the energy problem, human science and technology will also progress faster, perhaps in a short period of time to master the ability of interstellar travel, when human beings enter the galaxy, they can find other stars, establish their own "cosmic energy station", and begin to gradually colonize the universe.

Energy is the foundation of the development of advanced life, human beings currently use the resources of the earth's home planet, and in the future, they will go to the universe and use more abundant energy in the universe!

Increasing the retention time can lead to new applications. Apply scientific experiments to real-life situations. This discovery has great implications for scientific research. The effect is very large.

The biggest significance of improving the streamer is actually to make the whole time reach a very good running speed, and it can also make the whole space reach a very good speed, which is very perfect and very good.

It is of great significance for the construction of a global quantum communication network. The state of light can easily disappear, and this research has extended the storage time of light, which can lead to a series of innovative applications. It is a great advance in human science and technology.

Quantum USB flash drive is of great significance for the construction of a global quantum communication network. Li Chuanfeng introduced that in order to achieve quantum U disk, it is not only necessary to "retain light" with high precision, but also to improve the signal-to-noise ratio, which is also the direction of their next efforts.

It is of great significance to improve the light retention time, which is conducive to the development of science and technology to a certain extent, and can also promote the progress of society to a certain extent.

We can reserve some resources for the country, so that people can know some of the significance of light, know the development status of light energy, conduct good research and inventions, learn more about this knowledge, and so on.

The research group of Li Chuanfeng and Zhou Zongquan recently successfully increased the optical storage time to 1 hour, significantly breaking the world record of 1 minute set by the German team eight years ago, and taking an important step towards the realization of quantum USB flash drive.

Light is the basic carrier of modern information transmission, and fiber optic networks have spread all over the world. The storage of light is particularly important in the field of quantum communication, because quantum storage of light can be used to build quantum relays, so as to overcome transmission losses and establish long-range communication networks. Another long-range quantum communication solution is a quantum USB flash drive, which stores photons and transmits quantum information by transporting a USB flash drive.

Considering the speed of transportation vehicles such as airplanes and high-speed trains, the optical storage time of quantum USB flash drives needs to reach the order of hours to have practical value.

Quantum USB flash drive is of great significance for the construction of a global quantum communication network. Li Chuanfeng introduced that in order to achieve quantum U disk, it is not only necessary to "retain light" with high precision, but also to improve the signal-to-noise ratio, which is also the direction of their next efforts.

1. This is to store photons in an ultra-long premiere quantum memory, and then transmit quantum information by transporting a quantum USB flash drive;

2. To put it simply, it is to use an energy crystal to store the light, and then take it out after an hour, and find that the state information of the phase, polarization, etc. of the light is still well preserved, and it is realized by using a quantum U disk.

Our scientists have realized that we can store light for an hour, compared with German scientists who store light for a minute, and our technology has made great progress, and this technology will have a far-reaching impact in the future. Now that even light can be stored, which may be a kind of space technology in the future, and it feels like science is really omnipotent. <>

First, photon storage also plays a key role in information technology. You must know that now in all parts of the world, optical fiber is a very important medium for information transmission, how to store light, how to slow down light, this is a topic that many scientists are studying. Doing nothing about light allows us to make more effective use of light.

Now our scientists have been using quantum USB flash drives to store light for an hour, so that in the future, we can store light for a longer time and let the light stay is what scientists are committed to.

Second, we have already stored the light. In the past, people couldn't believe that we could store light, light for many people is a non-existent and inperceptible thing, just something we can see, then the speed of light is also a speed that human beings can't reach, and now through the invention of the quantum U disk, the future light may really be able to stay, and it will also have a huge impact on our technology. <>

3. Our scientists have set a new world record in the field of photonics. This time, our scientists can store an hour of light, which is also a new world record, I have to sigh, what our scientists are doing now is really powerful, our country's scientific level is slowly catching up with the world's level, in many high-end fields, our scientific strength is not weaker than other countries, and even our country has a lot of scientific water is already the world's first-line level. This is inseparable from the fact that our country has been vigorously developing science and popular science.

This will allow us to develop our future technology more rapidly. <>

4. ConclusionFor the terms quantum photons, there are many people who don't quite understand what they are, but as long as we know that our technology is a world record, the world is not as powerful as ours. Our scientists already have their place in the field of photonics, and we look forward to even more research results in the future.

This is because the level of science and technology in our country is very high, and there has been great progress, and at the same time, we have also made great contributions and research in this area, and we have achieved this point after many experiments.

Optical fiber networks are spread all over the world, and light has become the basic carrier of modern information transmission. The speed of light is as high as 300,000 kilometers per second, and reducing the speed of light or even allowing light to stay is the goal of the international academic community. The storage of light is particularly important in the field of quantum communication, because quantum relays can be built based on optical quantum storage, so as to overcome channel loss and establish large-scale quantum networks.

Another solution for long-range quantum communication is a quantum USB flash drive, which stores photons in ultra-long-lived quantum memory and then transmits quantum information by transporting the quantum USB flash drive directly.

So this is the quantum that plays a major role, and it is the development of science and technology in our country, which is very good.

Chinese scientists have increased the light storage time to 1 hourAn important step towards the realization of a quantum USB flash drive

A few days ago, the research team of Li Chuanfeng and Zhou Zongquan, academician Guo Guangcan of the University of Science and Technology of China, recently increased the optical storage time to 1 hour, greatly refreshing the world record of 1 minute of optical storage set by the German team in 2013.

Quantum USB flash drive is widely used in the fields of global satellite quantum communication and very long baseline interferometric astronomy measurement system. This achievement advances the optical storage time from the order of minutes to the order of hours, and meets the basic requirements of the optical storage life index of the U disk.

Next, they are expected to realize a quantum USB flash drive by optimizing the storage efficiency and signal-to-noise ratio, so that quantum information can be transmitted based on classical transportation vehicles and establish a new quantum channel.

The storage of light is particularly important in the field of quantum communication

Light is the basic carrier of modern information transmission, and fiber optic networks have spread all over the world. The storage of light is particularly important in the field of quantum communication, because Shenqin can build a quantum relay in order to use optical quantum storage, so as to overcome the transmission loss and establish a long-range communication network.

In the experiment, the optical signal was re-read as an optical signal after a series of operations such as optical excitation, spin excitation, and spin protection pulse, and the total storage time reached 1 hour, and the phase storage "fidelity" of the light was as high.

This improvement means that China has a new understanding of the substance of light, and the application method of light has also deepened. This technology of storing light can be applied to the USB flash drive, and the stored information is absolutely safe. This technology can also be used for information transfer.

It can speed up the transfer of information between two places. Improve work-life efficiency.
