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…
Nonlinear entanglement witnesses, covariance matrices and the geometry of separable states
Otfried Gühne, Norbert Lütkenhaus
Entanglement witnesses provide a standard tool for the analysis of entanglement in experiments. We investigate possible nonlinear entanglement witnesses from several perspectives.…
Stabilizer Quantum Error Correction with Qubus Computation
Casey R. Myers, Marcus Silva, Kae Nemoto +1
In this paper we investigate stabilizer quantum error correction codes using controlled phase rotations of strong coherent probe states. We explicitly describe two methods to measu…
On single-photon quantum key distribution in the presence of loss
Marcos Curty, Tobias Moroder
We investigate two-way and one-way single-photon quantum key distribution (QKD) protocols in the presence of loss introduced by the quantum channel. Our analysis is based on a simp…
Finding flows in the one-way measurement model
Niel de Beaudrap
The one-way measurement model is a framework for universal quantum computation, in which algorithms are partially described by a graph G of entanglement relations on a collection o…
A direct approach to fault-tolerance in measurement-based quantum computation via teleportation
Marcus Silva, Vincent Danos, Elham Kashefi +1
We discuss a simple variant of the one-way quantum computing model [R. Raussendorf and H.-J. Briegel, PRL 86, 5188, 2001], called the Pauli measurement model, where measurements ar…
