Chapter 69

The concept of quantum navigation system was proposed by three experts from the Massachusetts Institute of Technology in [-], and it immediately attracted the attention of the world.

Compared with existing satellite navigation systems, quantum navigation systems have many advantages.The most important two are that one is more accurate and the other is a higher safety factor.

The satellite navigation system adopts the principle of three-ball positioning, which has inherent disadvantages in positioning accuracy. At present, the equivalent error of the satellite orbit error is between 40 and [-] meters

In contrast, the quantum navigation system is an autonomous dead reckoning navigation system that uses inertial sensors, reference directions and initial position information to determine the orientation, position and speed of the carrier.

Because it is composed of quantum gyroscopes, quantum accelerometers, atomic clocks and other parts, the sensing measurement based on the interference effect of atomic matter waves and atomic spin has the excellent characteristics of high sensitivity and extremely low zero offset drift, which is different from the traditional inertial navigation system. In comparison, the measurement accuracy error is smaller, and the detection sensitivity to the change of the carrier attitude is higher.

Moreover, because quantum has the uncertainty principle and the non-cloning principle, that is, the unknown quantum state cannot be measured, and the quantum state cannot be accurately copied.

Therefore, the combination of the quantum positioning system and the quantum key agreement can improve the security of the quantum positioning system while realizing the confidential processing of information.

Moreover, the quantum navigation system relies on its own inertial components to achieve attitude adjustment and positioning, and does not need to receive signals from the orbiting satellites in real time for ranging and timing, which is a passive positioning system.It has the advantages of not radiating energy to the outside, good concealment, not easily disturbed, and high safety.

Therefore, as soon as the concept of quantum navigation system came out, it immediately attracted the attention of countries all over the world.

Many countries, such as the United States, the United Kingdom, China, France, and Russia, have invested in the research of quantum navigation systems.In the United States alone, nearly [-] scientific research institutions have launched this project.

But in the past few years, the theory of quantum navigation systems has not been perfected, let alone a prototype has been successfully developed.

It is for this reason that people were so shocked when they learned that the team of Xiang Nan, Howard, and Leslie of the California Institute of Technology had developed a quantum navigation system and had built a prototype.

……

"Does their quantum navigation system really work? How accurate is the positioning?"

"How did their navigation system solve the problem of disintegrating the superfluid vortex?!"

"Isn't Raj an astroparticle physicist, how can he even do a quantum navigation system?!"

The academic circles are talking about it, and they all want to find out.

However, the quantum navigation system has long been classified as top secret by the California Institute of Technology, and people who are idle have no right to read those research materials.

Compared with the curiosity of the academic world, the business world and the military coveted the system, and soon came to ask for cooperation.The military even demanded that it be classified as a military secret and handed over to it for safekeeping.

However, Caltech is not a vegetarian. It is a top university in the United States. It is full of peaches and plums. It has cultivated countless talents over the past century and has extensive contacts in the academic, business, and political circles.

Under such circumstances, it is simply impossible for the military to force the Caltech to hand over the quantum navigation system, and face heavy resistance.

Therefore, the result of the final game is that the military, the school, and the business community work together to develop the quantum navigation system, and the investment is as much as one billion US dollars.Of course this is only in stages.

After Xiang Nan, Howard, and Leslie received the funds, they also began to recruit troops to form a team to continue the research and development of the quantum navigation system.

At present, although the prototype has been built and works well, there are still many shortcomings.

First, the volume is still too large.If it could be shrunk down to the size of a walnut, it would have a wider range of applications.

The second is its core - the superfluid vortex, which is caused by liquid helium.And liquid helium needs minus 270 degrees to maintain a superfluid state.

The temperature is still too low.In order to maintain such a low temperature, a large amount of energy needs to be consumed.So if there is a superfluid with a higher temperature, not only will it save more energy, but it will also be less difficult to manufacture.

The third is that liquid helium will seep out from the edge of the instrument and slowly dissipate.Therefore, this system still has the problem of using time limit, and it also needs to be cracked.

To solve so many problems, Xiang Nan, Leslie, and Howard alone cannot do it.Therefore, they also need the assistance of other talents, so they have to form a team.

……

"I just received an email, and you can't guess who sent it." Howard said to Xiang Nan in surprise in the office.

"Who would it be?" Xiang Nan cheered.

"Elizabeth Plimpton!" Howard said excitedly.

"Wow, that well-known cosmic physicist?! She is an authority on quantum cosmology." Xiang Nan was also surprised when he heard it.

In the play, the doctor appeared in the No.20 episode of the third season.Although her professional level is indeed superior, even Sheldon, who has a high self-esteem, admires her.However, the chaos of her private life is also jaw-dropping.

"Yes, she is also very interested in our research, and even willing to come to our team to work." Howard said excitedly.

"Really?! That's really our honor." Xiang Nan said happily.

"Then do we want to invite her?" Howard asked immediately.

Although the R&D team is led by the three of them, it is Xiang Nan who is really in charge of the decision.

On the one hand, he came up with the idea of ​​the quantum navigation system, and he also insisted on negotiating with the school, and made the greatest contribution.

On the one hand, Leslie can't trust Howard, only Xiang Nan.Howard also has the best relationship with Xiang Nan.So he naturally became the core.

"You can let her try." Xiang Nan thought about it.

Although Elizabeth's private life is indeed a bit messy, her academic level is not bad.Moreover, with this well-known scholar joining in, it will also attract more talents to join.

"Then I'll send him an email right away." Howard said happily.

"Howard, aren't you so excited because she's a girl?" Leslie couldn't help shaking his head when he saw him like this.

"Of course... yes!" Howard said confidently.

Now the team has a total of four people (Peggy has joined the team), two men and two women, it is reasonable to say that they can be matched into two pairs.

But the reality is that Peggy likes Xiang Nan, Leslie also likes Xiang Nan, and no one likes himself.

Of course, he would have to find more girls to join the team, otherwise, he would be alone, which would be too pitiful.

Seeing him admit it shamelessly, Leslie was speechless for a while.

Just then, there was a knock on the office door.

Peggy opened the door, only to see Leonard standing outside the door angrily.
