Oct 2002. 4(5):256-259ISI:000179182700006https://hdl.handle.net/1808/281We propose a scheme for protecting one-qubit information against one erasure.. The scheme operates essentially by distributing quantum information over four qubits. Two versions of the method are considered: one of them is based on two spatially separated pairs of qubits, and the other is based on one pair of qubits and two spatially separated qubits.155557 bytesapplication/pdfen-USQubitErasure errorCollective decoherenceCnot operationA Scheme for protecting one-qubit information against erasure errorArticle10.1088/1464-4266/4/5/305openAccess
