A quantum-coherent photon--emitter interface in the original telecom band
Marcus Albrechtsen, Severin Krüger, Juan Loredo +10
Quantum dots stand out as the most advanced and versatile light-matter interface available today. Their ability to deliver high-quality, high-rate, and pure photons has set benchma…
Controlling emitter-field coupling in waveguides with a nanomechanical phase shifter
Celeste Qvotrup, Ying Wang, Marcus Albrechtsen +5
The ability to control light-matter interfaces with solid-state photon emitters is a major requirement for the development of quantum photonic integrated circuits. We demonstrate c…
Integration of a GaAs-based nanomechanical phase shifter with quantum-dot single-photon sources
Celeste Qvotrup, Ying Wang, Marcus Albrechtsen +5
We demonstrate a small-footprint electromechanical phase shifter with a compact active length of fabricated on a suspended GaAs membrane, offering versatile integr…
Deterministic photon source of genuine three-qubit entanglement
Yijian Meng, Ming Lai Chan, Rasmus B. Nielsen +10
Deterministic photon sources allow long-term advancements in quantum optics. A single quantum emitter embedded in a photonic resonator or waveguide may be triggered to emit one pho…
Programmable Nonlinear Quantum Photonic Circuits
Kasper H. Nielsen, Ying Wang, Edward Deacon +9
The lack of interactions between single photons prohibits direct nonlinear operations in quantum optical circuits, representing a central obstacle in photonic quantum technologies.…
