Epitaxial semiconductor quantum dots are among the best sources of quantum states of light. They deliver single photons and entangled photon pairs with high brightness and indistinguishability. We have recently established new methods for their coherent optical control and excitation with the goals of improving robustness and coherence. In the Austrian Science Fund (FWF) project BRAIDS we are working towards the generation of time-bin entanglement via dark exciton states. In our project within the Cluster of Excellence Quantum Science Austria we strive to observe collective effects of quantum dots in nanowires.
To lead the Innsbruck quantum dot activities, the Photonics group in the Department for Experimental Physics at the University of Innsbruck is inviting applications for a post-doc position. Candidates should have a background in experimental quantum- and/or nano-optics. Ideally, candidates have knowledge and experience in the following fields of expertise: single quantum emitters, coherent optical control, optical semiconductor physics.
We would like the successful candidate to start as early as possible with an initial appointment for two years. The position is will be a fixed-term employment contract level B1/3 with a minimum gross annual salary of € 70 200. In addition, the university offers several attractive benefits. The University of Innsbruck is committed to raising the quota of female employees and therefore particularly welcomes applications from qualified women.
The University of Innsbruck was founded in 1669 and is the biggest and most important research and education institution in western Austria, with over 25.000 students and more than 5.000 staff and faculty members.
TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
Experimental research in quantum photonics is structurally essential for addressing the transition of quantum light sources from laboratory-scale demonstrations to the robust components required for large-scale quantum communication and computing. This role type bridges the current technology readiness level gap by advancing the coherent control and entanglement fidelity of solid-state emitters, such as epitaxial semiconductor quantum dots. By optimizing the generation and manipulation of high-brightness single photons, these functions directly influence the viability of photonic quantum advantage and the development of tap-proof communication networks. Market signals indicate that the scalability of these architectures is currently gated by the deterministic integration of quantum emitters into nanophotonic structures, making such specialized research a critical determinant of future hardware interoperability and system-level performance.
The photonic quantum computing and communication sector is positioned as a primary frontier within the global quantum value chain, characterized by high projected growth and distinct advantages like room-temperature operation. However, the ecosystem faces significant macro constraints, primarily centered on optical losses and the probabilistic nature of photon interactions. The transition from physical to logical qubits necessitates accelerated experimentation with high-fidelity emitters that can be seamlessly integrated with existing semiconductor fabrication processes. This integration is vital for reducing the exorbitant development costs that currently hinder mass commercialization.
Current industry dynamics show a shift toward "quantum-ready" infrastructure where specialized hardware must interface with classical telecommunications networks. This requires a shift from isolated laboratory setups to modular, reproducible quantum processing units. Public funding cycles, such as the Cluster of Excellence Quantum Science Austria, are increasingly focused on these translation pathways, aiming to move beyond fundamental physics into system-level collective effects. As the market moves toward a projected value of several billion dollars by 2030, the availability of talent capable of navigating this hardware-research interface remains a pivotal bottleneck for both startups and established aerospace and defense entities.
Capability domains for this role type center on the intersection of epitaxial growth, coherent optical control, and nanophotonic engineering. Mastery of single quantum emitter dynamics is critical for ensuring the indistinguishability and brightness required for high-speed quantum information transfer. These capabilities enable the structural transition from bulk optics to integrated photonic circuits, which is the primary mechanism for collapsing system size and enhancing operational stability. Furthermore, expertise in coherent excitation methods provides the necessary leverage to improve qubit robustness against environmental decoherence, a prerequisite for fault-tolerant operations. This technical architecture facilitates the cross-functional coupling between fundamental semiconductor physics and the engineering of scalable quantum processing sub-systems.
