Are you passionate about quantum technologies and eager to further develop a Rydberg atom quantum computing platform as a 24/7 user-facility for hybrid quantum computing? Join us! We are looking for a candidate that drives the development of the experimental execution of the quantum computer and implements optimal control in dynamic quantum computing sequences.

Project and Job description

At TU/e, the ultracold atom lab of QT/e, part of the Eindhoven Hendrik Casimir Institute, is developing and constructing a pulse-based Rydberg atom quantum computing platform. This project is part of the KAT-1 Quantum Delta NL program on Rydberg-atom based hybrid quantum computing, which is a demonstrator program based on Quantum Inspire: the European quantum computer that is 24/7 online available for users. In 2024, our qubits will be added and we are looking for quantum engineers/postdocs to make this happen. The selected candidate will play a leading role in the development and integration of the control software, electronics and other hardware that manages the experimental qubit-platform. Moreover, they will drive the implementation of optimal control for the quantum computing and simulation platform within our quantum computer user-facility, working together with the qubit-hardware and software-hardware integration team.

Our platform for hybrid quantum computing and quantum simulation is formed around a quantum co-processor, with qubits based on ultracold (Rydberg) atoms. With optical tweezers these atoms are held in a lattice configuration with good controllability and readout. With excitation to Rydberg states, strong nearest-neighbour coupling can be realized, giving rise to multi-qubit entanglement. This platform is very suitable for specific tasks such as hybrid algorithms for quantum chemistry problems. For the Quantum Inspire platform the species of choice is atomic strontium, based on demonstrated high fidelity for single-atom gates. The goal for the QT/e platform is a robust setup to contain strontium atoms reliably in optical tweezers, with excellent single- and multi-qubit control. The setup aims for high stability to make it suitable for 24/7 online access.

Concretely, the selected candidate will guide the application and design of the control side of the project, involving software, electronics and other hardware. The project will specifically focus on fully automated computer control and creating and executing fast time sequences including real-time feedback. The platform should be suitable for pulse-based and gate-based hybrid quantum computing. Currently the Sr setup is controlled by the open software and hardware stack of ARTIQ but we and the selected candidate will also explore other control stacks or modules in collaboration with industry.  The Sr setup is based on a MOT and contains specific optical elements such as two microscope objectives, a spatial light modulator that controls the tweezer array and AODs for atom rearrangement. Additionally, within the ultracold lab, there is a ready to use ultracold rubidium atom testbed, for testing designs and ideas prior to implementation on the Sr computing platform.

The selected candidate will work together with several PhD candidates, fellow postdocs/quantum engineers (other vacancies available, please see V34.6152 and V34.6153), MSc students and the PI's within the ultracold atom team at QT/e. Moreover they will collaborate with the ultracold strontium lab at the UvA in Amsterdam, other partners within the Eindhoven Hendrik Casimir Institute and the wider quantum research network in the Netherlands. The work will be carried out in the Center for Quantum Materials and Technology (QT/e) within the CQT research group.

We welcome applications from candidates with experience in ultracold atoms and/or quantum computing related fields, who have a strong affinity with experimental work.  We are especially looking for candidates who take the initiative, work well in a team and know how to manage projects and guide PhD candidates.  

Other requirements are:

• PhD in experimental physics, preferably in the AMO field, or a comparable domain.
• Specific experience and affinity with experiment control and optimal control is desirable.
• Ability to conduct high quality research and technological development.
• Good team spirit, and interest to work in an international environment.
• Good written and oral communication skills in English are a prerequisite.
• Good supervision and collaborative skills.

Besides working on a state-of-art quantum computer and developing it into a user-friendly facility in an inspiring and international setting, we offer the following conditions of employment:

• A full-time employment (1.0 fte) for up to 3 years, with a gross monthly salary in the range of € 3.557 and € 5.439 (scale 10-11) based on your degree and previous experience. Besides that, we offer an annual holiday allowance of 8%, an annual end of the year bonus of 8,3%, a total of 41 days of paid holiday. The gross monthly salary and benefits are in accordance with Collective Labour Agreement for Dutch Universities.
• A meaningful job in a dynamic and ambitious university with the possibility to present your work at international conferences. 
• Free access to high-quality training programs for research and valorization, and didactical courses of the TEACH training program.
• A broad package of fringe benefits (including an excellent technical infrastructure, moving expenses, and savings schemes).  
• Family-friendly initiatives are in place, such as an international spouse program, and excellent on-campus children day care and sports facilities. 
• A Staff Immigration Team is available for international candidates, as are a tax compensation scheme (the 30% facility) and a compensation for moving expenses.
