How do we develop a quantum computer 550W

In "The Wandering Earth 2"

MOSS is a "550W" super quantum computer

It is the core intelligent host of the Navigator Space Station.

"550W" is "MOSS" in reverse

This is the name that "550W" gave himself.

So, the 550 series computers in the movie

What kind of technical system is it?

At the current level of human science

How to develop 550A or even 550W?

MOSS in "The Wandering Earth 2"

Quantum computers

550W is an important character in the movie "The Wandering Earth 2". It is set as a self-programming, networked, portable quantum computer, and to a certain extent determines the direction of the entire Wandering Earth plan.

Back to the 550 series and considering the technical path, if we need a sufficiently powerful computing device, and to achieve the 550W computing power in the movie, even if all the supercomputers in the world are added together, it is not enough. Therefore, to achieve the super computing power of the 550 series, for now, perhaps only quantum computers are the way out.

At present, the mainstream technology paths for humans to develop powerful computing devices are superconductivity, ion traps, photons, and topological quantum computers. Superconductivity and ion trap technologies require high vacuum and ultra-low temperature environments. Combined with the portability, small size, and high performance of the 550W in the movie, it can be inferred that the scientists in the movie chose photon quantum technology. In other words, the 550 series is likely to be a photon quantum computer.

The von Neumann architecture is the most common computer architecture today, namely the binary computer. Binary computers only have two basic states, 0 and 1, while quantum computers have not only these two basic states, 0 and 1, but also superposition states, which people call "quantum bits."

To illustrate with the simplest example of exhaustive enumeration, suppose there is a four-bit classical binary computer. It can only get one state per second, such as 0000 or 0101, so it takes 16 seconds to get all 24 states. A quantum computer with the same number of bits only needs one second to calculate all the permutations from 0000 to 1111. The key is that as the number of bits increases, the performance gap between quantum computers and traditional computers grows exponentially.

Quantum Volume

Currently, the mainstream technical paths of quantum computers are mainly superconductivity, ion traps, photons and topological quantum computers, etc. The number of quantum bits generally ranges from dozens to hundreds.

The movie "The Wandering Earth 2" did not directly use the qubit indicator for evaluation, but instead cited another concept, "Quantum Volume" (QV). Quantum volume is a quantum-specific performance indicator proposed by IBM. If qubits are the manufacturing level of automotive parts, then quantum volume is equivalent to zero-to-hundred acceleration, and the performance of different cars can be measured by this indicator.

Back to the movie, 550W introduced to Liu Peiqiang that its quantum volume is 8192. What does this mean? A less rigorous understanding is that it can process 8192 states of 2 at the same time, which far exceeds the number of all atoms in the observable universe.

Why is the quantum volume 8192?

If we look at 8912 alone, it is nothing more than 213. However, if we dig deeper into the Easter eggs in the movie, perhaps 8192 has a deeper meaning. The master of Zhang Peng and Nof in the movie is surnamed Wang, and it is speculated that he should be a first-class pilot. According to Zhang Peng's age, this master Wang should be born after 1965.

This reminds me of Martyr Wang Wei in the 81192 South China Sea collision accident. If Martyr Wang Wei had not died, he would have retired and become an instructor around 2020, and his students would have been Zhang Peng and Nof, who were about 18 years old at the time. Zhang Peng's instructions to Liu Peiqiang before detonating the nuclear bomb were also similar to Martyr Wang Wei's last words.

This spiritual heritage that transcends time and space is the unique romance of Chinese science fiction. Only a civilization with human existence, a civilization with emotional blood, and family and national culture can give years a meaning beyond numbers.
