It takes time for the quantum state to evolve. So in order to have a deep quantum circuit, we need longer coherence times.

Only NP-intermediate, which includes notably integer factorization:

A brain orgasm.

A positive definite matrix that is also a symmetric matrix.

Group of even permutations.

Note that odd permutations don't form a subgroup of the symmetric group like the even permutations do, because the composition of two odd permutations is an even permutation.

One major advantage: eukaryotes can do phagocytosis due to their cytoskeleton.
