When there is a small change in the shape and composition of two quantum systems that were intended to be exactly the same, a smaller but still critical frequency mismatch appears. These laser pointer changes cause the photons produced by the system to be slightly different in frequency rather than the exact copy that a quantum communication…

A more advanced and accurate method for measuring alcohol with a laser pointer
Germany has developed the latest laser alcohol measurement method. Spectral detection cures drunk driving. There is laser pointer often a big hidden danger in current driving safety, which is the problem of drinking and driving. Because generally speaking, people who drink alcohol tend to think that they are good. But the facts just proved that most people…
Laser pointer technology in textile processing
Laser technology is currently used in various fields, especially in aerospace, machinery manufacturing, sheet metal processing and other industries. laser pointer technology shows its advantages. As people’s demand for textiles grows, laser technology is expected to open up a new world in the field of textile processing. In traditional industry processing, laser technology has the advantages of…
How difficult is it to build a laser pointer spacecraft by Hawking?
The famous British physicist Stephen Hawking has a large number of fans in China. On April 12, as soon as Mr. Hawking’s official Weibo was launched, Chinese netizens went crazy laser pointer, and their fans quickly reached more than 2 million. May I ask who has such an aura? Not only that, Elder Hawking also made…
The laser pointer flight plan is feasible
This plan is totally unreliable in science? After seeing Hawking’s laser pointer plan, some people said that this time Hawking was talking crazy again. In fact, what Hawking said was not crazy. At least in theory, this plan is feasible. First of all, the “nano aircraft” is getting closer and closer to us. In recent years, nanotechnology…
Facing a very big laser pointer technical problem
Because the light from the sun provides endless energy, a spacecraft with a large solar sail can eventually laser pointer travel at a speed of 240,000 kilometers per hour. This speed is 4-6 times faster than the fastest spacecraft propelled by rockets today. That is, it is 6 times faster than the second universe and 4 times…
The way the laser pointer supplies energy is more complicated than nuclear energy
Hawking showed a screenshot of the video at the press conference. This nano-aircraft can be propelled by reflected light and accelerate to one-fifth the speed of light, which is much higher than the current spacecraft. Pang Zhihao believes that it is not difficult to propose the idea of a laser pointer “spacecraft” during the development of the…
Laser pointer technology that will fundamentally change future space communications
The communication problem is not without solutions. Scientists are already conducting experiments on laser pointer communication. Laser communication is 6 times faster than electromagnetic waves. On June 6, 2014, NASA announced that the agency used a laser beam to transmit a high-definition video from the International Space Station back to the ground, successfully completing a technology demonstration…
It can be realized in laser pointer technology first
The project will be led by the former director of NASA Ames Research Center Pete? Warden leads a committee of world-class scientists and engineers to provide advice, and its development may take several years. Although Milner invested 100 million US dollars in advance, the entire laser pointer project research and development may cost 5 to 10 billion…
Practical laser weapons development plan can be realized
Even in the future plan can be implemented. Since the development of space laser pointer technology is constantly progressing and breakthrough, in the near future, Hawkin’s idea will dream into reality. But Wang Si’s tide believes that the detector flying to the head of the horses and hiped. For more than 40 years, UFO and an extra-skilled…
