Robust photonic entanglement distribution via state-independent encoding onto decoherence-free subspace
Takashi Yamamoto, Kodai Hayashi, Sahin Kaya Ozdemir +2
Efficient and faithful implementation of quantum information tasks, e.g., quantum computing, quantum communication and quantum metrology, requires robust and state-independent deco…
Security of entanglement-based quantum key distribution with practical detectors
Masato Koashi, Yoritoshi Adachi, Takashi Yamamoto +1
We prove the unconditional security of an entanglement-based quantum-key-distribution protocol using detectors that respond to multiple modes of light and cannot distinguish betwee…
Quantum nonlocality without entanglement in a pair of qubits
Masato Koashi, Fumitaka Takenaga, Takashi Yamamoto +1
We consider unambiguous discrimination of two separable bipartite states, one being pure and the other being a rank-2 mixed state. There is a gap between the optimal success probab…
