Technology: breaking the hegemony that monopolizes the world

Gu Qing wrote a series of formulas like this on the "blackboard" [$$ C{ij}=\\sum{k=1}^{n} ai^k aj^k $$]

"Among them, $C{ij}$ represents the correlation between two quantum states, $ai^k$ and $a_j^k$ represent the $i$-th and $j$-th quantum states in the $k$-th state respectively. coefficient on a basis.

Initialize the state of the qubit, apply the corresponding quantum gate to each qubit, measure the qubit, obtain the measurement results, and then calculate the correlation based on the measurement results.

And we still need to modify and confirm several characteristics of this formula. What is the most important? "

Hearing this question, Li You's brows, which had just been furrowed because of deep thought, suddenly relaxed and he answered: "Observation data! Observation, measured changes!"

There was already a smile on Gu Qing's lips.

"Yes, whether we are people or objects, whether we observe directly or indirectly, there will be changes. In the field of scientific research, change is a good thing. But when data exploration and formulas are constant, although change is also a good thing, we must You must know the scope, magnitude, and direction of change!

You must think carefully about this issue. "

After leaving an assignment in class, Gu Qing continued: "Then there is the quantum Fourier transform QFT algorithm, which can be used to calculate the Fourier transform of polynomials. Tiangong, help me bring up the formula and put it on it. ”

This time, Gu Qing did not write it by himself, but chose to be "lazy".

"Okay, sir. The formula has been placed at the designated location. You can adjust it yourself, or..."

Gu Qing waved his hand, "Don't mess with that, enter [teaching mode], open the permission channel of the spiritual realm experiment server, and mobilize the big data of Jiulong in the cloud."

"You have entered [Teaching Mode], and your identity is being verified. The identity verification is successful. Welcome, please..."

Ignoring Tiangong's rigid way of greeting, Gu Qing looked at the long line of companies in front of him and sighed slightly.

"This company can make quantum chip computers, but if we humans were to push them, we would be exhausted every time."

【$$\\begin{aligned}\\phi(x)\u0026=\\frac{1}{\\sqrt{N}}\\sum……]

After clicking on this formula, Gu Qing continued without looking back: "As you can see, $\\phi(x)$ represents the Fourier transformed signal, $\\phi(k)$ represents the original signal, $ N$ represents the length of the signal.

The specific operation process is similar to the previous formula. Initialize the state of the qubit, apply the corresponding quantum gate to each qubit, then measure the qubit to obtain the measurement results, and then calculate the Fourier transform based on the measurement results.

The quantum Fourier transform QFT algorithm can also be implemented in the Python environment. "

At this point, Gu Qingshun wrote a paragraph: [python import numpy...

Initialize the qubit qc = QuantumCircuit(4, 4). Apply the X gate...Apply the H gate...Apply the CNOT gate...Get the measurement results counts = result.get_counts() print...]

Then click on this paragraph directly and say: "In this piece of code, I first initialized 4 qubits, then applied the X gate to the first qubit, applied the H gate to the second qubit, and then CNOT gates were applied to the first and second qubits, and finally measurements were made for all qubits.

By performing quantum calculations, we obtain the measurements.

Very simple, although very rough, but in the quantum world, sometimes roughness can have miraculous effects. For example, the quantum Melbourne spherical model QSBM algorithm is also implemented in Python.

But in addition to Python implementation, doesn’t our Jiuzhou language work?

The answer is, of course, no problem. "

"First initialize the qubit, give it a definition in the Heavenly Stems and Earthly Branches sequence library, and then other bits will be customized uniformly. Of course, it is not an arbitrary customization, but within certain rules. deal with.

Subsequently, measuring qubits, performing quantum calculations, and obtaining measurement results can also be brought into the Jiuzhou Fuxi algorithm we just developed.

Tiangong, take this string of data with you. "

[Okay, sir]

After entering the teaching mode, Tiangong is like the best assistant. Not only can he keep up with the progress of Gu Qing's lectures, he can also mobilize the database within his authority at the first time, provide Gu Qing with formulas and data, and even directly put the calculation tasks on the computer. Go to supercomputing and get results in the shortest time.

Of course, this is in the view of Li You, Zhang Yantai and others.

Tiangong completes all tasks within the established rules.

But the reality is that except when Gu Qing is present, at other times, even if Zhang Tianhao and An Hetang are present, Tiangong can bypass the orders of these "people" and decide on its own the database to be mobilized and the provider of computing power required for operation.

Zhang Yuanfeng's temporarily elevated authority is, at best, for the intelligent program AI Tiangong to make suggestions and inquiries before taking action.

In Jiuzhou Technology, especially in terms of technical core data and knowledge storage databases, Gu Qing has the highest authority, and these intelligent program AIs including Haizhi, Tiangong, and Xuanwu are all stewards and tools.

Although they have powerful authority, they can only rely on Gu Qing to survive and operate.

Li You, Zhang Yantai and others soon saw the results calculated by Tiangong.

"Fuxi's algorithm is really a gift from heaven. No matter which time I use it, I feel that we are asking a supercomputer to calculate how much one plus one equals. Obviously we just want to get the answer of two, but Fuxi will come up with a series of formulas. "

Hearing Li You's emotion, Gu Qing smiled and nodded.

“People tend to think too much and think in the wrong direction. Intelligent program AI is originally a neural learning algorithm, and they may also have glitches and errors.

Sometimes, when I see the performance of these intelligent program AI, I will sigh, as the ancients said: It is rare to be confused, and it has the most realistic performance at this time.

Ha ha. "

At this point, Gu Qing turned around and said to the other engineers: "That's it for today's class. Let's summarize it. Some of the special materials the company brought back from the moon have been analyzed. By then, everyone will Maybe more special materials will be used.

The top priority now, I personally think, is to study theory and then combine it with practice. Instead of focusing on innovating and innovating when materials and instruments are stuck in research and development difficulties.

Although this spirit is worth encouraging, for our company, it is a bit far-reaching.

Okay, each project team remember to receive the latest tasks. Next time I will review and check them one by one.

If there's a big problem with a project, don't blame me for not saying the bad thing first. "

Li You took a deep breath.

He knew that his boss Gu was not the kind of arbitrary person, but...
