Research group “Quantenbit AG” at the Johannes Gutenberg-University makes use of Ca+ ion qubits trapped in micromachined/fabricated radio frequency traps to implement a variety of quantum optics and quantum information experiments.
In our state-of-the-art quantum computer research labs, we operate several setups towards scalable and reproducible prototypes for a larger number of qubits (>50). Our team works on the implementation of useful quantum algorithms, especially in the field of quantum chemistry. We also have projects on the development of advanced vacuum and trap technologies and research projects with a stronger focus on fundamental physics ranging from single ion thermodynamics, Rydberg ions, vortex beam imaging and single ion sources.
What we offer:
We offer the chance to work independently in a leading quantum computing research group with well-funded state-of-the-art quantum computing labs. You’ll be part of an experienced group of dedicated PhD and Post-doctoral researchers working on multiple project, including a German quantum computing flagship project IQuAn, and multiple other projects funded by Germany (including SFB306), the European Union and USA.
Student Project Work / Intership / Summer projects
We are continuously offering projects for graduate students. The projects are focusing on building optical/laser setups, vacuum systems and electronics projects for measurement and control. This is the perfect chance to get acquainted with our group and the field of quantum information processing. Due to limited availability please apply early.
Master and Bachelor theses
We continuously offer projects in the field of cold ions and experimental quantum information processing. A master thesis/bachelor thesis offers the perfect opportunity to get to know this interesting research field. Please contact us for available projects.
We’re offering multiple fully funded Ph.D. positions (positions funded in accordance to German standard tariff starting TV-L E13 Grade 1 60%, progression to TV-L E13 Grade 3 75% by year 4 possible), ranging from working with a scalable quantum processors, development of advanced vacuum and trap technologies and quantum algorithm compilers, to more fundamental physics research projects on single ion thermodynamics, Rydberg ions, vortex beam imaging and with single ion sources. You can apply for one of the current topics listed below, and we’re always open to applications by outstanding candidates with interests not listed.
Work within SFB 306 project ,on mesoscopic 1D and 2D ion crystals. In subproject A1 we investigate collective light scattering off trapped ion crystals and in B1 we experimentally realize a thermodynamic model system of heat transfer, spin-boson coupling and collective quantum states.
Work with Rydberg Ions
Experiments with specific properties of ion crystals excited to Rydberg states, including large dipolar coupling, and alternative schemes for generating entanglement are investigated.
In addition to performing cutting edge research, you will have the opportunity to present your work on national and international conferences, visit collaborators and attend workshops. We also offer free German language classes at the university for interested students.
You should have an excellent university degree (Master of Science or equivalent) in physics or related fields (computer science, engineering, etc.) with relevant experience. Previous experience in the field of experimental laser physics, quantum optics and/or quantum computing is favourable. English fluency required; English academic writing skills favourable. Some projects can require German B2 level, majority does not have any German requirements.
We’re offering multiple research fellow positions in our quantum computer laboratories, as part of the ongoing projects IQuAn, ATIQ and EVAQS.
We are looking for applicants with strong interest in quantum computing and the following experience:
-PhD in the field of trapped ions, cold atoms, experimental quantum information or quantum optics.
-Fluency in Englisch and proficient academic writing skills.
-Experience in grant writing favourable.
We are also considering applicants with a PhD in computer science or electronics engineering and strong experience in quantum computing.
Please send your application (short summary of why you are suitable for this position) and the curriculum vitae electronically to Prof. Ferdinand Schmidt-Kaler. In case of any questions, please also do not hesitate to contact us.
