Phd Position in Quantum Optomechanics

**PhD Position in Quantum Optomechanics**:
**_Exploring the limits of quantum mechanics using mechanical systems_**

**Job description**:
One of the remaining open puzzles in modern physics is the transition between classical and quantum physics. While many models, like decoherence, have been proposed, experimental tests remain very challenging. One of the most promising and successful avenues for observing quantum effects at a macroscopic scale has been through quantum optomechanics, with recent demonstrations of entanglement between massive objects, teleportation and the creation of Schrödinger cat states, to name a few. The proposed project in the Groeblacher Lab at TU Delft will be exploring next generation mechanical structures to push the boundaries of the mass and complexity in quantum objects in order to probe the limits of quantum mechanics and to ultimately probe the elusive boundary region between classical and quantum physics. The project will involve design and fabrication of and experiments with quantum optomechanical systems based on phononic crystal devices.

At the Groeblacher Lab we have a vision: we thrive to be an inclusive place where a diverse mix of talented people want to come, to learn, to live their passion and do their best work. We are dedicated to promoting equality, creating a safe environment for everyone, and believe deeply in diversity of race, gender, sexual orientation, religion, ethnicity, national origin, age, socioeconomic background and all the other fascinating characteristics that make us different. We truly think diversity is a strength and working in a diverse environment, and being exposed to a variety of perspectives makes us stronger scientists and better human beings.

The Department of Quantum Nanoscience at the TU Delft is an exciting, collaborative environment with several world-renowned research groups. The department is focused on Quantum Theory, Quantum Information Science and Quantum Devices & Materials. The research is supported by state-of-the-art facilities, in particular the cleanroom facilities for realizing next-generation nanostructures.

(microfabrication, quantum optics, cryogenics,...), understand the underlying principles of quantum optomechanical systems (classical / quantum mechanics, condensed matter physics, optics) and to gain a deep knowledge in finite element simulation and advanced computer based experimentation. As a PhD student you will also be given the opportunity to supervise Master students and you will receive all the training allowing you to evolve into an independent scientist.

**Job requirements**:

- Masters or equivalent in (applied) physics or engineering
- Deep understanding of Quantum Physics
- Hands on experience with quantum optics experiments
- Experience with finite-element simulations
- Prior experience in nanofabrication and cryogenics is a plus
