Temporal ghost imaging with twin photons

Séverine Denis, Paul-Antoine Moreau, Fabrice Devaux +1

We use twin photons generated by spontaneous parametric down conversion (SPDC) to perform temporal ghost imaging of a single time signal. The retrieval of a binary signal containin…

Holographic quantum imaging: reconstructing spatial properties via two-particle interference

Nils Trautmann, Gergely Ferenczi, Sarah Croke +1

Two particle interference phenomena, such as the Hong-Ou-Mandel effect, are a direct manifestation of the nature of the symmetry properties of indistinguishable particles as descri…

Demonstrating an absolute quantum advantage in direct absorption measurement

Paul-Antoine Moreau, Javier Sabines-Chesterking, Rebecca Whittaker +5

Engineering apparatus that harness quantum theory offers practical advantages over current technology. A fundamentally more powerful prospect is the long-standing prediction that s…

Quantum Theory and Local Hidden Variable Theory: General Features and Tests for EPR Steering

Bryan J Dalton, Barry M Garraway, Margaret D Reid

In a previous paper tests for entanglement for two mode systems involving identical massive bosons were obtained. In the present paper we consider sufficiency tests for EPR steerin…

Will a decaying atom feel a friction force?

Matthias Sonnleitner, Nils Trautmann, Stephen M. Barnett

We show how a simple calculation leads to the surprising result that an excited two-level atom moving through vacuum sees a tiny friction force of first order in v/c. At first sigh…

Decision and function problems based on boson sampling

Georgios M. Nikolopoulos, Thomas Brougham

Boson sampling is a mathematical problem that is strongly believed to be intractable for classical computers, whereas passive linear interferometers can produce samples efficiently…

Reduction of Classical Measurement Noise via Quantum-Dense Metrology

Melanie Ast, Sebastian Steinlechner, Roman Schnabel

Quantum-dense metrology (QDM) constitutes a special case of quantum metrology in which two orthogonal phase space projections of a signal are simultaneously sensed beyond the shot…

A new device-independent dimension witness and its experimental implementation

Yu Cai, Jean-Daniel Bancal, Jacquiline Romero +1

A dimension witness is a criterion that sets a lower bound on the dimension needed to reproduce the observed data. Three types of dimension witnesses can be found in the literature…

Grassmann Phase Space Methods for Fermions. II. Field Theory

Bryan J Dalton, John Jeffers, Stephen M Barnett

In both quantum optics and cold atom physics, the behaviour of bosonic photons and atoms is often treated using phase space methods, where mode annihilation and creation operators…

Video recording true single-photon double-slit interference

Reuben S. Aspden, Miles J. Padgett, Gabriel C. Spalding

As normally used, no commercially available camera has a low-enough dark noise to directly produce video recordings of double-slit interference at the photon-by-photon level, becau…
