A photon loss tolerant Zeno CSIGN gate
Casey R. Myers, Alexei Gilchrist
We model an optical implementation of a CSIGN gate that makes use of the Quantum Zeno effect [1,2] in the presence of photon loss. The raw operation of the gate is severely affecte…
Strong Violations of Bell-type Inequalities for Path-Entangled Number States
Christoph F. Wildfeuer, Austin P. Lund, Jonathan P. Dowling
We show that nonlocal correlation experiments on the two spatially separated modes of a maximally path-entangled number state may be performed and lead to a violation of a Clauser-…
Spectral structure and decompositions of optical states, and their applications
Peter P. Rohde, Wolfgang Mauerer, Christine Silberhorn
We discuss the spectral structure and decomposition of multi-photon states. Ordinarily `multi-photon states' and `Fock states' are regarded as synonymous. However, when the spectra…
Entanglement generation by Fock-state filtration
K. J. Resch, J. L. O'Brien, T. J. Weinhold +2
We demonstrate a Fock-state filter which is capable of preferentially blocking single photons over photon pairs. The large conditional nonlinearities are based on higher-order quan…
GHZ-type and W-type entangled coherent states: generation and Bell-type inequality tests without photon counting
Hyunseok Jeong, Nguyen Ba An
We study GHZ-type and W-type three-mode entangled coherent states. Both the types of entangled coherent states violate Mermin's version of the Bell inequality with threshold photon…
Error tolerance and tradeoffs in loss- and failure-tolerant quantum computing schemes
Peter P. Rohde, Timothy C. Ralph, William J. Munro
Qubit loss and gate failure are significant problems for the development of scalable quantum computing. Recently various schemes have been proposed for tolerating qubit loss and ga…
