Quantum computers are affected by noise. The Earth is not an optimal location for a Quantum Computer due to all the dynamic events that occur on the planet. Mother Nature, human activity, Weather Patterns, animals, machinery, waves, and any noun that you can think of somehow is constantly evolving or moving in space and time resulting in a noisy arena for a Quantum Computer. The opposite is true for the Moon. It is a very still place. There are no waterfalls, planes, vehicles, storms, winds, consciousness, or any other noise inducing activity that occurs on the Earth and not on the Moon. Therefor, we can test if superpositions and quantum entanglement lasts longer on the Moon using entangled photons. If photons remain entangled longer or can be entangled at a higher rate than on the Earth, the Moon is a good candidate for a quantum computer. We can test for this using the Double Slit Quantum Eracer experiment. If more photons are entangled and remain entangled on the Moon than with using the same experiment on the Earth, a quantum computer should be built in the Moon. The Far side of the Moon may be an optimal location. We can also test higher rates or longer durations of quantum entanglement using a simpler experiment using a laser emitting photons to a BBO crystal resulting in two entangled photons and two image sensor which may determine if the entangled photons reached the sensors without decohering.
