Near-deterministic quantum teleportation and resource-efficient quantum computation using linear optics and hybrid qubits

Abstract

We propose a scheme to realize deterministic quantum teleportation using linear optics and hybrid qubits. It enables one to efficiently perform teleportation and universal linear-optical gate operations in a simple and near-deterministic manner using all-optical hybrid entanglement as off-line resources. Our analysis shows that our approach outperforms previous ones when considering both the resource requirements and fault-tolerance limits. DOI: 10.1103/PhysRevA.87.022326
