Efficient decoherence-free entanglement distribution over lossy quantum channels
Rikizo Ikuta, Yohei Ono, Toshiyuki Tashima +3
We propose and demonstrate a scheme for boosting up the efficiency of entanglement distribution based on a decoherence-free subspace (DFS) over lossy quantum channels. By using bac…
Demonstration of local expansion toward large-scale entangled webs
Toshiyuki Tashima, Tsuyoshi Kitano, Sahin Kaya Ozdemir +3
We demonstrate an optical gate that increases the size of polarization-based W states by accessing only one of the qubits. Using this gate, we have generated three-photon and four-…
Optimal local expansion of W states using linear optics and Fock states
Rikizo Ikuta, Toshiyuki Tashima, Takashi Yamamoto +2
We derive the maximum success probability of the circuits with passive linear optics for expanding an N-photon W state to an (N + n)-photon W state, by accessing only one photon of…
