Save the Bachelor of Heaven

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

Compared with the existing satellite navigation system, the quantum navigation system has many advantages. The most important two are, one is higher precision, and the other is 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 satellite orbit error is between five and forty 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 gyroscope, quantum accelerometer, atomic clock and other parts, the sensing measurement based on the interference effect of atomic matter wave 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, due to the uncertainty principle and non-cloning principle of quantum, that is, unknown quantum states cannot be measured, and quantum states cannot be accurately copied.

Therefore, combining the quantum positioning system with the quantum key agreement can improve the security of the quantum positioning system while realizing information confidentiality processing.

Moreover, the quantum navigation system relies on its own inertial software to achieve attitude adjustment and positioning, and does not need to receive signals from in-orbit satellites in real time for ranging and timing. It is a passive positioning system. It has the advantages of no external radiation energy, good concealment, less susceptible to interference, and high security.

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 forty scientific research institutions have launched this project.

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

It is precisely because of this that people were so shocked when they learned that the three-person team of Xiang Nan, Howard, and Leslie at Caltech had developed a quantum navigation system and had already built a prototype.

...

"Can 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 make a quantum navigation system?!"

The academic circles are discussing it one after another, and they all want to find out.

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

Compared with the curiosity of the academic circles, the business circles and the military are salivating over this 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 either. It is a top university in the United States, full of peaches and plums, and has cultivated countless talents in the past century. It has extensive contacts in academia, business, and politics.

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

Therefore, the final result of the game is that the military, the school, and the business community will jointly develop a quantum navigation system and invest as much as one billion U.S. dollars. Of course this is only temporary.

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

Although the current prototype has been built and works well, there are still many shortcomings.

First, the size 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 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 is consumed. Therefore, if there is a superfluid with a higher temperature, it will not only save more energy, but also reduce the difficulty of manufacturing.

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

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

...

"I just received an email, and none of you can 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 astrophysicist?! She is an authority on quantum cosmology." Xiang Nan was also surprised when he heard that.

In the play, the doctor appeared in the twenty-first 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 work in our team." Howard said excitedly.

"Really?! That's really our honor." Xiang Nan said happily when he heard that.

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

Although the R\u0026D team is led by the three of them, it is Xiang Nan who is really in charge of 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 the negotiation with the school, making the greatest contribution.

On the one hand, Leslie doesn'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 it." Xiang Nan thought for a while and said.

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

"Then I'll email him right away." Howard said happily when he heard that.

"Howard, aren't you so excited because she's a girl?" Leslie couldn't help shaking her head when she 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, and it is reasonable to make two pairs.

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

Then of course he needs to find more girls to join the team, otherwise, it would be too pitiful for him to be alone.

Seeing that he actually admitted it shamelessly, Leslie had nothing to say for a moment.

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

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