OFFER DESCRIPTION

This project explores the potential of multi-qubit gates for quantum computing on a superconducting qubit platform. The main goal is to develop superconducting architectures and control methods to efficiently generate multi-qubit states going beyond the current paradigm of decomposing all state manipulations into single and two-qubit gates. We design and realize parametric couplers [McKay et al., Phys. Rev. Applied 6 (2016)] connecting multiple superconducting qubits and investigate multi-qubit operations that allow us to entangle multiple qubits at the same time. We explore multi-qubit entangling interactions and evaluate the maximally possible number of qubits coupled to a single coupler.  The final goal is to address the question if there is an advantage in using multi-qubit gates over traditional two-qubit gates in practical experiments. To this end, we assess the efficiency of multi-qubit gates in an algorithmic context targeting, e.g., a quantum chemistry problem, such as determining the ground state and energy spectrum of a small molecule using the variational quantum eigensolver (VQE). The devices and methods developed in this project will enhance the scalability of superconducting qubit platforms and the efficiency of quantum algorithms. This project is carried out in collaboration with the TU Munich/Walther-Meißner-Institute in Germany.

Specific Requirements

Eligibility criteria and requirements

The candidate should have a solid background in the experimental control of quantum systems, ideally with a focus on superconducting circuits. The candidate must be curious to learn or expand his expertise in micro- and nanofabrication, quantum circuit design, microwave engineering, signal processing, low-temperature physics, instrumentation, control and measurement automation, data analysis and/or coding. Good knowledge of Python is desired.

QUSTEC programme follows MSCA eligibility criteria:

Required level of experience is ‘Early Stage Researcher’ according to the definition in the 2018-2020 work programme of the Marie Skłodowska-Curie actions: Applicants must, at the date of the respective call deadline of QUSTEC, be in the first four years (full-time equivalent research experience) of their research careers and have not yet been awarded a doctoral degree.

Mobility criterion: The applicants must not have resided or carried out their main activity (work, studies, etc.) in the country of the future host organisation for more than 12 months in the 3 years immediately before the call deadline of QUSTEC. Short stays such as holidays are not taken into account. For refugees under the Geneva Convention, the refugee procedure (i.e. before refugee status is conferred) will not be counted as a period of residence/activity in the country of the host organisation.
