PhD Position in Quantum Optomechanics at TU Delft
Vacancy ID: 2143 | Deadline: 23 May 2025 | Location: Mekelweg 5, 2628CD, Delft, The Netherlands
Weekly Hours: 38 hours | Salary Range: €2901–€3707/month | Published On: 1 May 2025
Research Context: Probing the Boundary Between Classical and Quantum Worlds
The Groeblacher Lab at Delft University of Technology (TU Delft) invites applications for a highly competitive and fully funded PhD position in Quantum Optomechanics. This opportunity is embedded within one of the most pioneering scientific challenges of our time: the exploration of the transition from classical to quantum behavior in physical systems. While various theoretical models such as decoherence have been suggested, experimental realizations remain sparse and technically demanding. The PhD candidate will contribute to pushing the experimental boundaries of mass, size, and complexity in quantum systems through innovative work with phononic crystal-based optomechanical devices.
Research Objectives and Scope
This project seeks to advance the field of macroscopic quantum physics by designing, fabricating, and characterizing next-generation quantum optomechanical systems. The ultimate aim is to reveal and test the elusive boundary where classical physics gives way to quantum behavior. Within this framework, recent advancements in the field—including entanglement of massive bodies, quantum teleportation, and Schrödinger cat states—provide an inspiring foundation for the upcoming research.
The candidate will gain hands-on experience in:
Nanofabrication techniques specific to phononic crystals
Quantum optics and laser-based experimental techniques
Cryogenic systems for ultra-low temperature measurements
Finite element modeling for precision design and simulation
Data acquisition and control systems for complex quantum experiments
The project is hosted in the Department of Quantum Nanoscience, a hub for high-impact research in quantum information, quantum theory, and advanced quantum devices.
