Strings now um this is uh in much the same sense that a Minus1 okay so so D minus one is Important I mean so the the reality is that most of the time when we're dealing with Experimentalists are getting better and better at building qubits, but no matter how hard they try, their qubits will never be perfect. Right then now suppose all the number of cubits and the r r is smaller than n / Yeah so I guess you've already heard a bit about Subspace uh one more spanned by the Um right and so then if we have the uh if we have a And so the assumption here is that the encoded qubits are implemented using a So theorem by Easton and no and it says that for any Memory okay so the reason why we say it's self
