PhD position in Qubit hardware for hybrid quantum computing

Are you passionate about quantum technologies and eager to further develop a Rydberg atom quantum computing platform as a 24/7 user-facility, in the context of the Flagship program EuRyQa? Join us! The overall objective of EuRyQa is to establish Rydberg quantum processors as a leading platform for scalable quantum computing. We develop and bring together the technology for realizing deep quantum circuits from four complementary European platforms, provide Europe-wide benchmarking on concrete computational problems and the next crucial steps towards fault-tolerant quantum computing.

Our platform for hybrid quantum computing and quantum simulation is formed around a quantum co-processor, with qubits based on ultracold atoms. We operate both a rubidium and strontium-based testbed. With optical tweezers these atoms are held in a lattice configuration with good controllability and readout. With excitation to Rydberg states, strong nearest-neighbor 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. The goal for the platform is a robust setup to contain single 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 candidate will focus on:

• Experiments for characterization, calibration and operation of Rydberg atom-based quantum computer.
• Utilize the Rb clock transition as qubit for long coherence times of >100ms.
• A complete and scalable quantum instruction set optimized for large qubit arrays.
• Employment of pulse-optimized multi-qubit gates that reduce the overall gate time (using intensity- and frequency-shaped laser pulses).
• Implementation of quantum error correction protocols optimized for Rydberg QC. Collaboration between experimental and theoretical groups and industry partners to achieve the best performance.
