Quantum information processing by systems including quantum computers and quantum networks have been known since some years. Despite the potential advantages in exploiting the quantum mechanics to process information, there are still several problems to solve in the path towards large-scale quantum computers and quantum networks.
The invention provides a method that allows operating with qubit without needing out-of-band control and signaling. In particular, the patented method allows to write and read classical information on quantum information, using the error syndromes of a QECC, without destroying the quantum superposition.
