Scattering induced spatial superpositions in multi-particle localization
James S. Douglas, Keith Burnett
We describe how quasiclassical relative positions of particles emerge in an initially delocalized quantum system as scattering of a probe beam is observed. We show that in the mult…
Phase-locked indistinguishable photons with synthesized waveforms from a solid-state source
Clemens Matthiesen, Martin Geller, Carsten H. H. Schulte +6
Resonance fluorescence in the Heitler regime provides access to single photons with coherence well beyond the Fourier transform limit of the transition, and holds the promise to ci…
Fundamental limitations to information transfer in accelerated frames
Eduardo Martin-Martinez, Dominic Hosler, Miguel Montero
We study communication between an inertial observer and one of two causally-disconnected counter accelerating observers. We will restrict the quantum channel considering inertial-t…
Fundamental Limits of Classical and Quantum Imaging
Carlos A. Pérez-Delgado, Mark E. Pearce, Pieter Kok
Quantum imaging promises increased imaging performance over classical protocols. However, there are a number of aspects of quantum imaging that are not well understood. In particul…
Super-resolving multi-photon interferences with independent light sources
Steffen Oppel, Thomas Büttner, Pieter Kok +1
We propose to use multi-photon interferences from statistically independent light sources in combination with linear optical detection techniques to enhance the resolution in imagi…
Ultimate limits to quantum metrology and the meaning of the Heisenberg limit
Marcin Zwierz, Carlos A. Pérez-Delgado, Pieter Kok
For the last 20 years, the question of what are the fundamental capabilities of quantum precision measurements has sparked a lively debate throughout the scientific community. Typi…
