My Fintech Empire

After Fang Hong finalized the strategic decision, he left Qunxing Capital headquarters, and left the implementation of the strategy to Qiu Guangcheng and the front-line core management to implement it.

In the next period of time, the most anticipated thing is to see if Wall Street has entered the game, and Fang Hong is also waiting patiently.

But two days later, a piece of news from the technology and academic circles caught Fang Hong’s attention, because this news was related to Quantitative Capital. The media reported that a research team under Quantitative Capital announced that their research in the field of quantum computers had successfully realized A time crystal.

Some media even described it as "the third type of perpetual motion machine". When Fang Hong saw these keywords, the word "minke" popped up subconsciously in his mind.

However, this is indeed the latest research breakthrough announced by a team of physicists led by Chen Yu under Quantitative Capital. Although Quantitative Capital started as an investment management company, few of its core team are from so-called academic backgrounds. of finance majors.

His team is almost a group of top mathematicians and physicists. In order to study the intelligent quantitative trading model, Chen Yu's team was "forced" to study artificial intelligence. After studying artificial intelligence, they found that the computing power was not enough.

Then it was discovered that the computing power of classical computers was definitely not enough to support more powerful artificial intelligence, but quantum computers could. For this reason, Chen Yu and his team were "forced" to study quantum computers.

From these, we can also see where the biggest advantage of Chen Yu's team lies.

His team can transform into a scientific research team in a flash. If Chen Yu's team is only composed of a group of finance majors from colleges, it is simply impossible for them to study AI, quantum computers, and chips.

"This kid is indeed a genius..." Fang Hong, who was in the study at home at the moment, watched the news content and boasted to Chen Yu. After a while, he connected with Chen Yu through a video connection.

As soon as the video connection was connected, Fang Hong asked directly: "What the hell is that 'time crystal' you have built? It can also be related to quantum computers. A group of media even described it as the so-called third type." Perpetual motion machine, the word perpetual motion machine has come out, what's the situation?"

This incident really touched some of Fang Hong's blind spots in knowledge. Although he also knows a lot about computers and the Internet, he also understands computer programming, and his scientific literacy is better than most people, but after all, he was not a professional in his previous life. Scientists doing research.

After a while, Chen Yu in the video said with a smile: "We didn't create the concept of 'time crystal'. It was first proposed by Wilcek, a theoretical physicist in the country of Magnesia."

Hearing this, Fang Hong immediately said: "It turned out to be him. I know this scientist. He is one of the discoverers of 'asymptotic freedom' in quantum chromodynamics QCD."

Chen Yu nodded and replied: "That's right, Wilczek also won the 2004 Nobel Prize in Physics for his QCD."

Fang Hong immediately asked: "So, what is this time crystal?"

Chen Yu explained in an orderly manner: "Generally speaking, it is an open system, which has the characteristics of broken time-translation symmetry, and cannot achieve thermal equilibrium with the surrounding environment. That is to say, it presents periodicity in time, and it can have It repeats its own state regularly, and secondly, the change of this state does not consume any energy. Wilczek first proposed this concept, and this time we successfully produced a time crystal."

"The reason why it is called a time crystal is that when the atoms and molecules of matter are arranged neatly in space according to a certain periodicity, they will present a regular geometric shape at the macroscopic level, so it is similar to a crystal, and time Crystals are the thing that has similar properties in time."

"If you observe a time crystal, you will find that this thing will show different results at different times, and it will have a fixed periodicity over time. If you observe it twice at an integer period, you will get exactly the same result. The two results. For time crystals, the operation of time translation no longer has continuous symmetry but has become a lattice-like discrete symmetry,"

Hearing Chen Yu's description, Fang Hong immediately said: "That is to say, the translational symmetry of space corresponds to the conservation of momentum in physics, and this time translational symmetry corresponds to the conservation of energy? Right?"

Hearing this, Chen Yu couldn't help nodding his head repeatedly. It seems that although the big boss is not professional, he also has a scientific foundation, so the communication will not be too strenuous. He immediately said: "Yes, the process of changing the time lattice will not consume Any energy, this is because the movement itself is in a stable ground state of minimum energy, in other words, compared to letting it stop, it is more stable to keep moving."

Fang Hong couldn't help asking curiously: "Why does this peculiar property exist?"

Chen Yu replied: "There is no conclusion yet, but it may be related to the zero-point energy and the Casimir effect. However, the time crystal is not a so-called perpetual motion machine. The media is pure nonsense. The movement of the time crystal is not accompanied by energy transfer. It's a completely spontaneous movement."

Fang Hong couldn't help thinking: "Is the phenomenon of spontaneous motion? This is not uncommon in condensed matter physics. For example, under certain conditions, many superconductors will spontaneously generate closed circulation."

Chen Yu nodded and said: "Yes, for example, if you bring a magnet close to the annular superconducting material, it can generate current in the ring. Even if you remove the magnet at this time, the annular current will always exist, because the superconducting ring at this time It is in the steady state with the lowest energy, and if the current is stopped, additional energy injection is required.”

The big boss really has a scientific foundation, which indirectly shows that it is difficult to fool him.

Fang Hong asked again: "Is there a possibility that this kind of superconducting circulation can also change periodically, can it also be regarded as a kind of time crystal?"

Chen Yu immediately shook his head and explained: "No, the time crystal we are referring to is a state that repeats itself regularly. The focus is on the 'self state'. It has not changed, while the time crystal has changed its basic properties, such as density, conductivity and so on."

Fang Hong couldn't help but suddenly said: "So that's the case."

Chen Yu continued: "The unique stability of time crystals is very suitable for use in quantum computers. You should also know that the interaction between microscopic particles and macroscopic objects is easy to decohere, which makes them lose their quantum properties. Therefore, quantum computers The interior of the crystal is actually very error-prone, and the stability of the time crystal can be used to avoid the occurrence of decoherence, so as to improve the lifetime of the quantum state and reduce the error rate."

At the end, Fang Hong couldn't help laughing and said: "These media really know how to exaggerate, I was almost fooled, I thought you were going to make a quantum computer soon, but this is also a very rare achievement breakthrough, which is enough to prove The research of the Qi team in the field of quantum computing has gone ahead of the world."

Fang Hong was also a little startled when he saw the news report before.

No, immediately connect with Chen Yu directly to ask what's going on.

If the quantum computer makes a revolutionary breakthrough, if this technology is lit, it will be terrible, and it will trigger a series of technological innovations.

However, Fang Hong was not disappointed. Quantum computers are not cutting-edge technology if they are so easy to break through. After all, it is only halfway through 2014, and Moore's Law has not yet come to an end.

If Chen Yu can come up with a quantum computer at this point in time, then it will definitely be the rhythm of black technology.
