Incomplete Detection of Nonclassical Phase-Space Distributions
M. Bohmann, J. Tiedau, T. Bartley +3
We implement the direct sampling of negative phase-space functions via unbalanced homodyne measurement using click-counting detectors. The negativities significantly certify noncla…
Trading quantum states for temporal profiles: tomography by the overlap
Johannes Tiedau, Valery S. Shchesnovich, Dmitri Mogilevtsev +5
Quantum states and the modes of the optical field they occupy are intrinsically connected. Here, we show that one can trade the knowledge of a quantum state to gain information abo…
Full statistical mode reconstruction of a light field via a photon-number resolved measurement
I. A. Burenkov, A. K. Sharma, T. Gerrits +5
We present a method to reconstruct the complete statistical mode structure and optical losses of multimode conjugated optical fields using an experimentally measured joint photon-n…
Limits on the heralding efficiencies and spectral purities of spectrally-filtered single photons from photon pair sources
Evan Meyer-Scott, Nicola Montaut, Johannes Tiedau +4
Photon pairs produced by parametric down-conversion or four-wave mixing can interfere with each other in multiport interferometers, or carry entanglement between distant nodes for…
Heralded orthogonalisation of coherent states and their conversion to discrete-variable superpositions
Regina Kruse, Christine Silberhorn, Tim J. Bartley
The nonorthogonality of coherent states is a fundamental property which prevents them from being perfectly and deterministically discriminated. To circumvent this problem, we prese…
