An Idea for Interplanetary Quantum Computer System that Reduces Noise

Today, I was on the train on the way to Tokyo, and an idea came to my mind. I was imagining, since noise that causes decoherence in quantum computer is reduced when it is on a cooler state, I thought that it will be good if quantum computers is in an another planet, let’s say the moon. One would then relay information to the quantum computer by a communication satellite and send computation data there.

The computation data is then shared among quantum computer cluster placed on different parts of the planet where it is dark (meaning cooler) and where it is brighter. The brighter side doesn’t do computation as there are higher probability of error due to higher noise and also charges batteries with solar panel. The quantum computers in the darker part compute with less error due to lower temperature and thus less error.

When the computation is done on this quantum computer cluster, it sends the data back to earth via the communication satellite.

This is the idea I thought today.

I asked GPT-4 ChatGPT to elaborate on this idea. Here is the result:

Expanding on your idea, here are additional concepts and possibilities to consider:

1. Quantum computer orbiting stations: Instead of placing quantum computers on the Moon or another planet, consider having them on orbiting stations around Earth or other celestial bodies. This could potentially minimize latency in communication and offer better control over the environment.
2. Cryogenic cooling systems: Implement advanced cryogenic cooling systems that can maintain extremely low temperatures for quantum computers, regardless of their location. This could allow for more efficient operation and reduce the need for relocating them to colder environments.
3. Quantum computer networks: Create a global network of quantum computers that can communicate with each other and distribute the computational load. This could allow for increased efficiency and redundancy, as well as provide a means of compensating for fluctuations in temperature or other environmental factors.
4. Adaptive error correction: Develop advanced error correction algorithms that can adapt to the changing conditions of the quantum computer’s environment. This would allow the computers to maintain optimal performance regardless of temperature fluctuations or other environmental factors.
5. Space-based quantum internet: As quantum computing becomes more widespread, a space-based quantum internet could be established to connect quantum computers across the solar system. This network would enable secure and efficient quantum communication, and could also serve as a backbone for interplanetary data transmission.
6. Artificial intelligence optimization: Utilize AI algorithms to optimize the scheduling and distribution of computation tasks among the quantum computer cluster. The AI could take into account factors such as temperature, energy availability, and latency to ensure that each quantum computer operates at peak efficiency.
7. Space-based quantum computing infrastructure: Develop a comprehensive infrastructure for space-based quantum computing, including communication satellites, power generation and storage systems, and maintenance facilities. This would enable the efficient operation of quantum computers in space and facilitate their integration into Earth-based networks.
8. Modular quantum computer designs: Design quantum computers to be modular and easily upgradeable, allowing for the replacement of individual components as technology advances. This would increase the lifespan of the quantum computers and reduce the need for costly replacements.
9. Quantum computing for space exploration: Utilize the space-based quantum computers for space exploration tasks, such as simulating the behavior of celestial bodies, analyzing data from telescopes and sensors, and planning optimal spacecraft trajectories.
10. International collaboration: Encourage international collaboration on the development and deployment of space-based quantum computers. This would help to pool resources and expertise, and could lead to more rapid advancements in the field of quantum computing.
