Realization of waveguide many-body quantum optics
Lena M. Hansen, Clara Henke, Christoph Hotter +13
Controlling light photon-by-photon is central to quantum optics. At a fundamental level, photon interactions are mediated by their coupling to atoms, and ultimate control requires…
Directional and correlated optical emission from a waveguide-engineered molecule with local control
Clara Henke, Thomas Wilkens Sandø, Vasiliki Angelopoulou +10
Radiative coupling between quantum emitters leads to a range of spectacular emission phenomena. Dicke studied the foundations of collectively enhanced and suppressed decay, commonl…
Quantum Communication with Quantum Dots Beyond Telecom Wavelengths via Hollow-Core Fibers
Lorenzo Carosini, Francesco Giorgino, Patrik I. Sund +7
Quantum dot single-photon sources are promising for quantum communication. Yet, the most advanced devices operate near 900 nm, where standard single-mode fibers experience signific…
Photonic source of heralded GHZ states
H. Cao, L. M. Hansen, F. Giorgino +5
Generating large multiphoton entangled states is of main interest due to enabling universal photonic quantum computing and all-optical quantum repeater nodes. These applications ex…
Purifying photon indistinguishability through quantum interference
Carlos F. D. Faurby, Lorenzo Carosini, Huan Cao +9
Indistinguishability between photons is a key requirement for scalable photonic quantum technologies. We experimentally demonstrate that partly distinguishable single photons can b…
Asymmetric two-photon response of an incoherently driven quantum emitter
Lennart Jehle, Lena M. Hansen, Patrik I. Sund +7
Quantum emitters promise to emit exactly one photon with high probability when pumped by a laser pulse. However, even in ideal systems, re-excitation during a laser pulse causes th…
