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…
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…
Multi-photon emission from a resonantly pumped quantum dot
Francesco Giorgino, Patrik Zahálka, Lennart Jehle +4
Resonance fluorescence of natural or artificial atoms constitutes a prime method for generating non-classical light. While most efforts have focused on producing single-photons, mu…
Non-classical excitation of a solid-state quantum emitter
Lena M. Hansen, Francesco Giorgino, Lennart Jehle +5
The interaction between a single emitter and a single photon is a fundamental aspect of quantum optics. This interaction allows for the study of various quantum processes, such as…
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…
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…
Controlling the Photon Number Coherence of Solid-state Quantum Light Sources for Quantum Cryptography
Yusuf Karli, Daniel A. Vajner, Florian Kappe +14
Quantum communication networks rely on quantum cryptographic protocols including quantum key distribution (QKD) using single photons. A critical element regarding the security of Q…
Programmable multi-photon quantum interference in a single spatial mode
Lorenzo Carosini, Virginia Oddi, Francesco Giorgino +7
The interference of non-classical states of light enables quantum-enhanced applications reaching from metrology to computation. Most commonly, the polarisation or spatial location…
Single-active-element demultiplexed multi-photon source
Lena M. Hansen, Lorenzo Carosini, Lennart Jehle +5
Temporal-to-spatial demultiplexing routes non-simultaneous events of the same spatial mode to distinct output trajectories. This technique has now been widely adopted because it gi…
