Quantum computers are expected to offer phenomenal increases of computational power. In spite of many proposals based on various physical systems, scalable quantum computation in a fault-tolerant manner is still beyond current technology. Optical models have some prominent advantages such as relatively quick operation time compared to decoherence time. However, massive resource requirements and the gap between the fault tolerance limit and the realistic error rate should be significantly reduced. Here, we develop a novel approach with all-optical hybrid qubits devised to combine advantages of well-known previous approaches. It enables one to efficiently perform universal gate operations in a simple and near-deterministic way using all-optical hybrid entanglement as off-line resources. Remarkably, our approach outperforms the previous ones when considering both the resource requirements and fault tolerance limits. Our work paves an efficient way for the optical realization of scalable quantum computation.
