Abstract

Quantum states are very delicate, so quantum error-correction procedures are believed to be essential for the successful implementation of quantum communications or computations. To erroneous qubits where the position is known, Grassl et al. [Phys. Rev. A 56, 33 (1997)] proposed an error model which they called quantum erasure channel. In this paper we present a quantum code capable of protecting nqubit of information against the occurrence of t erasures. This code is based on GHZ states.
