Originally, I thought creating terminator robots in the Doomsday would be an easy task, but that idea was not easy to implement. Not only did it require programming, but even processor chips capable of independent computation were extremely rare.
The technological gap between civilian and household use in the Doomsday was enormous. If one were to collect chips by scavenging, most of the recovered chips would be civilian versions, which might be fine for daily work, but when it came to combat, the complex battlefield environment would turn terminators made from low-end civilian chips into dull, blockheaded automatons.
"Aren't you guys very advanced here? You can't even build an automated combat robot. Is there no other way?" Feng Jun complained.
Actually, it wasn't that the technology in the Doomsday wasn't advanced enough; people here had already gone to space, capable of building Space Farms and colonizing Mars and the Moon. However, to maintain the stability of human society, and also due to a certain fear of advanced artificial intelligence, this area of technology had been significantly restricted in its development. The human technology tree in this world was a bit skewed; other directions flourished, but artificial intelligence remained uneven and severely limited.
Gu Yunyun said, "We need to find a way to get chips. We can try to deeply optimize the combat program or make some lower-spec versions. They don't need to be too smart, just able to identify friend or foe and open fire."
"There's another way: build encrypted signal towers and use quantum communication for signal transmission," Gu Yaoyao suddenly said.
After watching the movie, Gu Yaoyao had finished her snacks. She was usually a person of few words. So, she turned her interest to the tablet Feng Jun had brought. In just the short time Feng Jun and Gu Yunyun were talking, she had disassembled the tablet into many pieces.
"The computing power of Quantum Computers is enormous. Besides research, controlling tens of thousands of combat robots is also very easy. If we can build encrypted communication towers and use quantum communication's encryption method to transmit signals, then we can use the Quantum Computer in the Refuge to directly control every combat robot. This saves time on training combat AI and searching for chips," Gu Yaoyao explained what she had just said.
The method Gu Yaoyao proposed was to use unified central control. The advantage of this was that it saved the two most troublesome steps; as long as the robots were in place and the communication system was built, they could be quickly deployed to the battlefield.
In fact, many small UAVs and combat equipment in the Doomsday were controlled in a similar way, such as the UAV swarm used by Huaicheng District during the Zombie Tide. Most of them adopted central computers or shared cellular communication technology. A swarm consisting of one UAV and hundreds of UAVs, connected via a local wireless network, could share the computing power of the chips within their bodies, thereby performing coordinated combat and completing complex tasks.
This small swarm technology was very simple and easy to get started with. The UAV swarm itself was part of the intelligent AI operating system. The more UAVs connected, the more computing power was shared, making them more flexible in responding to battlefield situations. Moreover, such a swarm had no central computer; unless the entire swarm of UAVs was completely destroyed, destroying only tens or hundreds of them would not be able to destroy this swarm combat network. Without large computers and expensive chips, a stable UAV strike group could be quickly established on the front line.
However, the weakness of this UAV swarm was also very obvious: its anti-interference ability was very weak. Once strong interference appeared on the opposite side during combat, the combat effectiveness of the UAV swarm would be greatly reduced. However, because everyone's technological content had decreased after the Doomsday, shared cellular UAVs were very popular in the Doomsday. Before the war, the three major combat forces were still more willing to use quantum communication, which had stronger anti-interference capabilities, or to configure several computers with stronger computing power on the front line.
Feng Jun was very interested in the plan proposed by Gu Yaoyao, but compared to her sister Gu Yunyun, this little girl was a woman of few words. Although the two sisters looked alike, the younger sister always had a cold expression no matter what she did, as if only food could arouse her interest.
Longmen Town now also had over ten thousand troops and had opened up new territory in Yanqing Industrial Park, but communication had always been very chaotic. In Longmen Town and nearby areas, a local network built with IEM terminals was used, while the slightly more distant Yanqing Industrial Park could only use radio for communication.
It was impossible to integrate all the forces at hand relying solely on local networks and radio. Local networks were similar to cellular networks, requiring reliance on personal IEMs in Huaicheng District. Therefore, communication in Longmen Town relied on trustworthy individuals transmitting via their own IEMs. As for Yanqing Industrial Park, because it was too far, only radio could be used, and radio was a common technology in the Doomsday. Feng Jun had not formulated any codebooks or the like, so every time he contacted Yan Xin and Song Peng, he could only speak vaguely.
The government before the Doomsday must have already built a complete communication network, covering the entire Earth with satellites and communication towers, but these were all destroyed by the war. Now, what Feng Jun needed was to establish his own quantum communication tower and connect it to the Quantum Computer in QD10096 Shelter.
"Then we just need to sort out the communication device. How long will it take to make a quantum communication tower?" Feng Jun asked.
Gu Yaoyao rolled her eyes, "My brother-in-law, what do you think this thing is? Can it be built so easily? The photon crystal communication module inside is very precise, and its manufacturing difficulty is probably second only to a Quantum Computer. Trying to hand-make it with your current equipment? It would probably take a hundred years to build one."
Afterward, Gu Yunyun explained some conditions for quantum communication to Feng Jun. Although she didn't know much about this, she had heard some basic principles. Quantum communication requires the use of quantum bits as the basic unit of information. These quantum bits can be the quantum states of photons, electrons, or other particles, and their quantum properties such as superposition and entanglement are the basis of quantum communication. Quantum teleportation relies on quantum entanglement, which is a peculiar quantum phenomenon where the quantum states of two or more particles become so intimately connected that the state of one particle immediately affects the state of another, no matter how far apart they are. Quantum teleportation in quantum communication utilizes this entanglement to achieve long-distance information transfer. The most widely popularized technology before the Doomsday was photon communication technology.
However, because quantum states are very fragile and easily interfered with by the external environment, precisely controlling and measuring quantum systems is crucial. This requires highly precise equipment and technology to ensure the integrity and accuracy of quantum information. Thanks to breakthroughs in optoelectronic chip technology on the Doomsday technology line, all quantum communication towers are made of optoelectronic chips. However, manufacturing such chips requires extremely strict environments and equipment, and factories capable of manufacturing these optoelectronic chips were heavily targeted during the war.
