"Sit, yes, drink tea? Or coffee?" After Pan Jingyuan left, Qiao Yu asked.

In order to treat guests, he asked a box of tea from Tian Dao. It is said that it is a very good tea.

As for coffee, the kind of fast -soluble coffee that is casually bought in the school supermarket is also a brand goods.

"Coffee." Peter Schultz hesitated two seconds later.

"Haha, Peter, you really have taste."

Qiao Yu laughed and complimented, and then took out a bag of quick -soluble coffee from the drawer, got up to help Peter Schultz pick up a cup, and then found that there seemed to be no spoon.

A little embarrassing, all the secrets, it doesn't matter, anyway, this guy is not here to drink coffee.

Sure enough, seeing Qiao Yu handed the coffee like this, Peter Schultz was stunned and said nothing. He took it and put it aside. Then he said, "Joe, you promised me when you were in Philadelphia.

of."

"Wait, Peter, I will tell you an idea. After you hear it, you will find that this is a very wonderful idea!"

Qiao Yu directly transferred the topic.

Just kidding, this is his home, how could this guy hold his nose?

Peter Schultz really hooked, and asked, "Oh? What do you think?"

Obviously the opposite hook.

Qiao Yu said solemnly: "Before explaining this idea to you, you need to answer my question first. Do you also think that using Hilbert Space to study quantum physics far behind this era?"

Peter Schultz looked at Qiao Yu and said, "Joe, you can only say that the description of the actual measurement of Hillbert's space is not intuitive.

The completeness of Hilbert's space is very elegant. It can also make up for its shortcomings with the Li's algebra. "

Qiao Yu shook his head and refuted: "Peter, you can't say that he is your compatriots because Hilbert is your compatriots. The fact is that Hilbert's space does not directly reflect the essence of physical phenomena.

For example, the process of wave function collapse, it is more like a mathematical abstraction, not a real evolution description.

Another example is the quantum state measurement, we only get the probability distribution, and the nature of the vector in Hilbert's space is useless. Did I say it wrong? "

Peter Schultz looked at Qiao Yu, who was flying, took a deep breath and asked, "So you plan to create a complete space that can be used to study quantum physics and can solve all the problems of Hilbert space?"
