Journal ArticleDOI
Observation of cross phase modulation in cold atom gradient echo memory
Anthony C. Leung,K. S. I. Melody,Aaron D. Tranter,Karun V. Paul,Geoff Campbell,Ping Koy Lam,Benjamin Buchler +6 more
TL;DR: In this paper , the authors demonstrate and characterize a scheme free from these limitations using gradient echo memory with inferred single photon phase shifts of 0.07 ± 0.02 μrad, which is in agreement with theoretical modelling.
Journal ArticleDOI
Sensitive single-photon test of extended quantum theory with two-dimensional hexagonal boron nitride
Tobias Vogl,Tobias Vogl,Heiko Knopf,Heiko Knopf,Maximilian Weissflog,Ping Koy Lam,Falk Eilenberger,Falk Eilenberger +7 more
TL;DR: In this paper, the disappearance of higher-order interference using single-photons emitted from two-dimensional hexagonal boron nitride was shown to have been achieved using a single-beam approach.
Proceedings ArticleDOI
Demonstrating hybrid quantum effects with two entangled laser beams
Boris Hage,Jiri Janousek,Seiji Armstrong,Thomas Symul,J. Bernu,Helen M. Chrzanowski,Ping Koy Lam,Hans-A. Bachor +7 more
TL;DR: In this article, two mode quantum state tomography was used to extract single photon Fock states solely based on homodyne detection, demonstrating the strong quantum features of this entangled pair of laser beams.

Coherent Time-Delayed Atom-Light Interferometer
TL;DR: In this paper, the authors present experimental observations of interference between an atomic spin coherence and an optical field in a Λ-type gradient echo memory, where the interference is mediated by a strong classical field that couples a weak probe field to the atomic coherence through a resonant Raman transition.
