Reading out a quantum bit
... In order to get the result of a quantum algorithm we need to read out the state of the qubits in the out register when the algorithm is done. As we will see later one also needs to read out certain qubits during the computation if we want to perform error correction. On the algorithm level a read-ou ...

Bulk Locality and Quantum Error Correction in AdS/CFT arXiv
... mentioned in the introduction, that is that no nontrivial operator in the CFT can commute with all local CFT operators on Σ. To avoid this contradiction it must be the case that the representations of φ(x) in different wedges are not really all the same operator on the CFT Hilbert space. We can see ...
