Generation of Pure-State Single-Photon Wavepackets by Conditional Preparation Based on Spontaneous Parametric Downconversion
Alfred B. U'Ren, Christine Silberhorn, Reinhard Erdmann +4
We study the conditional preparation of single photons based on parametric downconversion, where the detection of one photon from a given pair heralds the existence of a single pho…
Generation of two-photon states with arbitrary degree of entanglement via nonlinear crystal superlattices
Alfred B. U'Ren, Reinhard K. Erdmann, Manuel de la Cruz-Gutierrez +1
We demonstrate a general method of engineering the joint quantum state of photon pairs produced in spontaneous parametric downconversion (PDC). The method makes use of a superlatti…
Experimental Realization of Maximum Confidence State Discrimination for the Extraction of Quantum Information
Peter J. Mosley, Sarah Croke, Ian A. Walmsley +1
We present the first experimental demonstration of the maximum confidence measurement strategy for quantum state discrimination. Applying this strategy to an arbitrary set of state…
Entanglement fidelity of quantum memories
K. Surmacz, J. Nunn, F. C. Waldermann +3
We introduce a figure of merit for a quantum memory which measures the preservation of entanglement between a qubit stored in and retrieved from the memory and an auxiliary qubit.…
Direct, Loss-Tolerant Characterization of Nonclassical Photon Statistics
Daryl Achilles, Christine Silberhorn, Ian A. Walmsley
We experimentally investigate a method of directly characterizing the photon number distribution of nonclassical light beams that is tolerant to losses and makes use only of standa…
