"I'm actually quite puzzled...Why are you not afraid of being beaten?" Yang Xiaoman took a kitchen knife and said while chopping vegetables: "It's useless to scold...it's annoying me to death."

The words fell,

Yang Xiaoman suddenly brought the kitchen knife to Xu Mang's neck and asked seriously: "Are you having a baby tonight? I want to practice another number!"

Xu Mang:???

...

HKUST,

Professor Yuan Fei and other colleagues are studying the issue of quantum key distribution at the thousand-kilometer level. Although they approached Xu Mang, the news they got was not that good. Xu Mang took a negative attitude towards this plan of HKUST.

.

Too...

Not to mention Xu Mang, even Yuan Fei and other professors, including the entire team... are a little worried about this plan. After all, this is something unimaginable in the world. Three thousand kilometers of quantum key distribution,

What is this concept?

No one can do it!

"well?"

"Didn't Academician Xu say...it can be solved in a week?" An expert present asked curiously: "It's been a week now...when will he help us solve it?"

"How is that possible!"

"Academician Xu is in Sweden, how will he solve it for you now?" Yuan Fei said with a bitter smile: "And Academician Xu is very busy now. He has a lot of things on his hands, so we'd better not bother him..."

After hearing what Yuan Fei said,

Everyone couldn't help but sigh. Indeed... Academician Xu's current identity is no longer what he used to be. It takes a lot of face to ask him for help. The reason why he was able to contact him this time was entirely because Professor Yuan Fei and Xu Mang had collaborated before.

.

at present,

One of the difficulties of this project is the bit error rate. Yuan Fei and a few people have a preliminary solution, which is to systematically optimize the existing equipment, including using cutting-edge signal capture, alignment and tracking systems, and synchronization technology

.

but...

These optimization technologies can only solve the superficial phenomenon, and the deeper things cannot be perfected.

Of course, this is just a small problem among many. There are also practical application problems that translate into high security, the speed of key generation, the compatibility of wavelengths with telecommunications optical fiber networks, the integration of optical fiber networks and quantum communication networks, etc.

These all need to be solved...but China's current technology seems to be unable to do so.

"what to do?"

"This will take at least ten years!" Yuan Fei said with a wry smile: "And this is still the most ideal stage. Each problem... takes a year, and they will all be solved in ten years, but you will definitely encounter various problems.

Question, then I will be confused again.”

The words fell,

Professor Yuan Fei sighed and said silently: "Let's work hard together..."

Sudden,

The phone rings,

Yuan Fei frowned. He was not very happy to answer the phone at this time. Finally, he picked up the phone and took a look and found that it was Academician Xu calling.

"Shh!"

"Academician Xu called!"
Chapter completed!
