The problem comes from having to measure the quantum state of every quantum particle in that banana and transmitting the bits necessary to perform the state transfer. We're talking destructively reading out well over 10^25 particles, turning that into tens of yottabytes of data, and then transmitting that data with error correction over distances that you can't just... you know... ship a banana over.

And then you'd have to receive that data in a way that either lets you perform the transfer in real time, or in a way that lets you store that data so you can transfer the quantum states one by one or in small batches.

And that's if you're okay with "Scanning" the original banana in a way that destroys the banana as yous scan it. Not the quantum states, the actual banana: the destructive read of particles will cause nuclear reactions and so very quickly you're no longer scanning "a banana" but "messed up subatomic partilces".
