Quantum error correction against photon loss using NOON states
Marcel Bergmann, Peter van Loock
The so-called NOON states are quantum optical resources known to be useful especially for quantum lithography and metrology. At the same time, they are known to be very sensitive t…
Higher-order EPR correlations and inseparability conditions for continuous variables
E. Shchukin, P. van Loock
We derive two types of sets of higher-order conditions for bipartite entanglement in terms of continuous variables. One corresponds to an extension of the well-known Duan inequalit…
Synchronization of optical photons for quantum information processing
Kenzo Makino, Yosuke Hashimoto, Jun-ichi Yoshikawa +4
A fundamental element of quantum information processing with photonic qubits is the nonclassical quantum interference between two photons when they bunch together via the Hong-Ou-M…
Ultrafast Long-Distance Quantum Communication with Static Linear Optics
Fabian Ewert, Marcel Bergmann, Peter van Loock
We propose a projection measurement onto encoded Bell states with a static network of linear optical elements. By increasing the size of the quantum error correction code, both Bel…
Generalized conditions for genuine multipartite continuous-variable entanglement
E. Shchukin, P. van Loock
We derive a hierarchy of continuous-variable multipartite entanglement conditions in terms of second-order moments of position and momentum operators that generalizes existing crit…
