At DTU Physics, four PhD students will join a broad quantum science effort spanning experimental quantum optics, optomechanics, microscopy and theory/software for photonic quantum computing. The positions are based in the Section for Quantum Physics and Information Technology (QPIT) and bigQ – Center for Macroscopic Quantum States , within an international environment that combines advanced quantum-optical laboratories, quantum information theory and large-scale computational research. The advertised projects address distinct but connected frontiers in quantum physics. In Quantum Opto-Acoustics , the student will work on cavity-enhanced Brillouin interactions to control an acoustic mode in a quartz crystal and develop quantum-control and optical readout techniques for non-classical mechanical states, optical–acoustic entanglement and quantum memories. In Quantum-Enhanced Optomechanics , the focus is a density-phononic-crystal membrane in a high-finesse optical cavity, with work aimed at quantum-limited measurements, low-noise control, optical cooling and feedback, and interfaces with squeezed light. In Quantum-Enhanced Microscopy , the student will explore spatial-mode demultiplexing and related quantum measurement ideas to improve nanoparticle detection, localization and chemically selective Raman microscopy. In Fault-Tolerant Continuous-Variable Quantum Computing with GKP States , the project combines theory and software to develop GKP-based architectures, decoders, logical codes, noise models and simulation tools for scalable photonic quantum computing. Across the projects, students will work closely with experienced researchers and technical staff, contributing to precision measurements, optical cavities, quantum algorithms, simulation software, benchmarking and analysis of noise and performance limits. The advert emphasizes both experimental and computational research in a collaborative, international setting at DTU Physics.
