The concept of quantum navigation system was proposed by three experts from the Massachusetts Institute of Technology in 2001, and it immediately attracted attention from all over the world.

Quantum navigation systems have many advantages over existing satellite navigation systems. The two most important ones are, first, higher accuracy, and second, higher safety factor.

The satellite navigation system uses the three-sphere positioning principle, which has inherent disadvantages in terms of positioning accuracy. The current equivalent error of satellite orbit error is between five and forty meters.

In comparison, 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 vehicle.

Because it is composed of a quantum gyroscope, a quantum accelerometer, an atomic clock 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-bias drift, which is consistent with traditional inertial navigation systems. In comparison, the measurement accuracy error is smaller, and the detection sensitivity for carrier attitude changes is higher.

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

Therefore, combining the quantum positioning system with the quantum key agreement improves the security of the quantum positioning system while achieving information confidentiality.

Moreover, the quantum navigation system relies on its own inertial components to achieve attitude adjustment and positioning. It does not need to receive signals from orbiting satellites in real time for ranging and timing. It is a passive positioning system. It does not radiate energy outwards, has good concealment, and is not easy to detect. It has the advantages of being immune to interference and having high security.

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

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

However, 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 precisely for this reason that people were so shocked when they learned that a team of Xiang Nan, Howard, and Leslie from Caltech had developed a quantum navigation system and had built a prototype.

…

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

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

"Isn't Raj an astrophysicist? How can he even develop a quantum navigation system?!"

There was a lot of discussion in the academic circles, and they all wanted to find out.

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

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

However, the California Institute of Technology is not a vegetarian. It is a top university in the United States, with students all over the world. It has cultivated countless talents over the past century and has extensive connections in academia, business, and politics.

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

Therefore, the final result of the game was that the military, the school, and the business community worked together to develop a quantum navigation system, investing as much as one billion U.S. dollars. Of course, this was only a phased development.

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

Although the prototype has been built and is running well, it still has many shortcomings.

First, the size is still too large. If it can be reduced to the size of a walnut, its application range will be wider.

Second, its core, the superfluid vortex, is caused by liquid helium. Liquid helium requires minus 271 degrees to maintain a superfluid state.

This temperature is still too low. In order to maintain such a low temperature, a large amount of energy needs to be consumed. Therefore, if there can be a superfluid with a higher temperature, it will not only save more energy, but also the difficulty of manufacturing will be reduced.

Third, liquid helium will seep out from the edge of the instrument and slowly dissipate. Therefore, this system still has a service life problem and 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. You can't guess who sent it." In the office, Howard said to Xiang Nan in surprise.

"Who could it be?" Xiang Nan cheered.

"Elizabeth Plimpton!" Howard said excitedly.

"Wow, that famous cosmologist?! She is an authority on quantum cosmology." Xiang Nan was surprised when he heard this.

In the play, this doctor appears in the twenty-first episode of the third season. Although her professional level is indeed superior, even Sheldon, who thinks highly of himself, admires her highly. However, the chaos of her private life also makes her...

People were stunned.

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

"Really?! That's really our honor." Upon hearing this, Xiang Nan said happily.

"Then should we invite her?" Howard asked immediately.

Although the R&D team is led by the three of them, Xiang Nan is really responsible for making decisions.

On the one hand, he was the one who came up with the idea of ​​the quantum navigation system, and he was the one who advocated for the negotiation with the school, and made the greatest contribution.

On the one hand, Leslie couldn't trust Howard, only Xiang Nan. Howard also had the best relationship with Xiang Nan, so he naturally became the core.

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

Although Elizabeth's personal life is indeed a bit messy, her academic level is not bad. And having this well-known scholar join will also attract more talents to join.

"Then I'll reply to his email right away." Howard said happily after hearing this.

"Howard, are you so excited just because she is a girl?" Seeing his appearance, Leslie couldn't help shaking her head.

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

There are now a total of four people in the team (Peggy has joined the team), two men and two women, so it stands to reason that they can form two pairs.

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

Then of course he needs to find more girls to join the team, otherwise, he would be all alone, which would be really pitiful.

Seeing that he admitted shamelessly, Leslie was speechless for a moment.

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