Superfluidic Quantum Computer?

Click For Summary
SUMMARY

The discussion centers on the feasibility of creating a quantum computer utilizing fluidic logic with superfluid helium-4 as the medium. The primary advantage identified is the potential reduction of friction losses, although this benefit is questioned regarding its significance in fluidic systems. Key challenges include the requirement to maintain temperatures below 2K and the complications arising from the unique properties of superfluids. Overall, the practicality of this approach remains uncertain due to these significant drawbacks.

Would it be possible to make a quantum computer with fluidic logic (https://en.m.wikipedia.org/wiki/Fluidics), using a superfluid, like liquid Helium-4, as the the "current"?

I think the question I would ask is, what are you trying to gain from switching to this very awkward material? The only advantage I would see is reduction of friction losses, but I'm not sure that's even a major concern in fluidics. On the downside, now you have a device that needs to stay below 2K, and you get hard-to-deal-with side effects.
