The brain it's not a good place to perform quantum computing.
It's wet and warm, quantum computing needs hyper dry and cold environment.
Of course there are quantum phenomena in the brain as any other piece of matter, but it does not perform quantum computing.
But the neurons do classical computing, so the mind algorithm someday will be cracked and we'll be able to create an artificial mind.
And/or we'll be able to transfer our minds to a better substrate.
Actually there's a project doing this right now:

When this project will be finished, they'll run this brain model in the future exascale computers:

Then we hope to get the so dreamed artificial intelligence, a mind that have the entire internet as memory and will have the processing power higher than all human brains combined.
I hope to be alive to see all these things.
