Energy-time entanglement from a resonantly driven quantum dot three-level system
M. Hohn, K. Barkemeyer, M. von Helversen +8
Entanglement is a major resource in advanced quantum technology, where it can enable secure exchange of information over large distances. Energy-time entanglement is particularly a…
Tools for the Performance Optimization of Single-Photon Quantum Key Distribution
Timm Kupko, Martin v. Helversen, Lucas Rickert +6
Quantum light sources emitting triggered single photons or entangled photon pairs have the potential to boost the performance of quantum key distribution (QKD) systems. Proof-of-pr…
Accessing the dark exciton spin in deterministic quantum-dot microlenses
Tobias Heindel, Alexander Thoma, Ido Schwartz +11
The dark exciton state in semiconductor quantum dots constitutes a long-lived solid-state qubit which has the potential to play an important role in implementations of solid-state…
Path-controlled time reordering of paired photons in a dressed three-level cascade
Samir Bounouar, Max Strauß, Alexander Carmele +8
The two-photon dressing of a "three-level ladder" system, here the ground state, the exciton and the biexciton of a semiconductor quantum dot, leads to new eigenstates and allows o…
A bright triggered twin-photon source in the solid state
Tobias Heindel, Alexander Thoma, Martin von Helversen +11
A non-classical light source emitting pairs of identical photons represents a versatile resource of interdisciplinary importance with applications in quantum optics and quantum bio…
Exploring Dephasing of a Solid-State Quantum Emitter via Time- and Temperature- Dependent Hong-Ou-Mandel Experiments
A. Thoma, P. Schnauber, M. Gschrey +9
We probe the indistinguishability of photons emitted by a semiconductor quantum dot (QD) via time- and temperature- dependent two-photon interference (TPI) experiments. An increase…
