@rpcarnell: Interesting point about the brain and quantum computers. I had never thought of that.

I do not know much about quantum computers yet I came up with a, very theoretical, idea: Use a optical lattice-type quantum computer but instead of qubits use what I call "quterits, mixing Catuṣkoṭi Logic with quantum mechanics instead of Boolean logic, as I like tetrapartite logic (I even use it in my speech.) :lol:


Does this actually exist as a physical device or is it a scientific speculation.

It exists only as my own speculation; sorry about the ambiguity.

Isn't decoherence the main issue with quantum computers at the moment?

Yes. Masahiro Hotta has suggested Quantum energy teleportation (QET) as a way to avoid thermal decoherence:

Quote:
Much after the transportation, dynamical evolution of the system begins and then heat is generated. Thus, the time scale for effective energy transportation by QET is much shorter than that of heat generation. This property is one of the remarkable advantages of QET. Due to this property, QET is expected to find use use as an energy distribution scheme inside quantum devices that avoids thermal decoherence and would thus assist in the development of quantum computers.

But most of this is still in its early stages but a realistic experimental proposal using a semiconductor exhibiting the quantum Hall effect
has been suggested:
