Chapter 475 Can predict the future

Gao Ruiya asked Gou Sheng: "Isn't predicting the weather a one-sided prediction of the future?"

[Gousheng: You are right. There was a time when people cursed the inaccurate weather forecasts of national and even international television stations.

It was clearly forecast to rain tomorrow, but I kept the umbrella in hand for a week and not a single raindrop fell.

As a result, everyone lost confidence in the weather forecast and stopped paying attention to the weather forecast.

That's not because the meteorological station wants to make some international joke, it's because they really can't make accurate predictions - the amount of input information is not enough.

Today's weather forecasting relies on inputting hundreds of thousands of information variables into supercomputers from atmospheric changes observed by satellites, wind direction and strength recorded on the ground, as well as temperature and humidity, and surface information, such as mountainous landforms.

Let those huge supercomputers predict the weather, so we have the accurate weather forecast we have today. 】

Gao Ruiya sighed: "Yes! If you think about it, it's not a big deal now that Zhuge Liang borrowed the east wind!"

[Gou Sheng: Nowadays, weather forecasts are becoming more and more accurate. Idioms like "the wind and clouds are strange" are probably going to disappear, because future generations of students really can't understand how unpredictable weather changes are. 】

Gao Ruiya suddenly understood something: "The same principle applies to other fields, such as stocks!
As long as all economic activities and related information within the scope of the stock market are input into the supercomputer, the direction of the stock market can also be predicted! "

[Gou Sheng immediately denied Gao Ruiya: You are wrong to think this way, because you underestimate the most important variable "people"!
Using supercomputers to predict human social activities is tantamount to using an abacus to calculate astronomical figures. 】

When Gou Sheng noticed Gao Ruiya's extremely disappointed expression, he changed the subject.

[Gou Sheng: But it’s different when it’s put on a quantum computer!

As we all know, the calculation method of home computers, including supercomputers, uses binary to perform operations. Each calculation unit can only be in a "1" or "0", while each calculation unit of a quantum computer is in a quantum entangled state. ——That is, this calculation unit can be "0" or "1"! 】

Gao Ruiya said impatiently: "I know this. Didn't our country also build a quantum computer two years ago? It's called 'Nine Chapters' and 'Nine Chapters Two'.

100 trillion times faster than today’s fastest supercomputer! "

[Gou Sheng is more patient than Gao Ruiya: Congratulations, you are all ready to answer!But you just know it and don’t know why.

You must know that even supercomputers and home computers work on the same principle. Even if supercomputers are hundreds of millions of times faster than ordinary computers, it is only because the supercomputer's chips and memory are huge.

The calculation unit of quantum entangled states is an expanded Hilbert space. Compared with the two, it can be said to be a dimensionality reduction blow to classical computers.

If quantum computers are used to predict human social activities such as financial markets, as long as sufficient information is input, then the direction of various indexes can be accurately predicted at your fingertips! 】

A conversation with Gou Sheng made Gao Ruiya fall into deep thought. She had heard about the butterfly effect and quantum computers for a long time. She and her brother had even created artificial intelligence, but the combination of these could actually give humans a glimpse of prediction. Opportunities for the future!
