Superfluidity was first discovered as a property of Helium-3. Near absolute zero Helium turns into a superfluid, loses all viscosity, and acts as a macroscopic object that can be described by a single quantum mechanical wave function. On earth superfluid quantum computers are vulnerable to decoherence due to the liquid's sensitivity to external vibrations, etc. Many experiments have been conducted on the space shuttle and ISS to control globules of magnetic fluids (containerless processing). Could decoherence be easier to control in space, leading to large and powerful Helium-3 Superfluid Quantum Computers?
