Designing and characterizing multiple subsystems of a multi-qubit superconducting processor 

Artificial atoms based on superconducting qubits with transition energies in the microwave regime (~4-8 GHz) have emerged as one of the promising platforms for building large-scale quantum processors. With the invention of error correcting codes, these physical qubits can be scaled to implement logical qubits for demonstrating useful quantum algorithms in such systems. A recent experiment by Google involving superconducting qubits demonstrated 'quantum supremacy' over a state-of-the-art classical supercomputer, showing the remarkable potential of small-scale quantum systems. 
 
Building scalable-quantum systems with superconducting qubits require high-coherence qubits, high-fidelity single- and two-qubit gates, carefully engineered microwave-circuit design of the multi-qubit chip among many others. Keeping the fabrication challenges aside, a superconducting device designer must make a multitude of design choices to optimize the various components required to design large-scale quantum processors. Typically, these include the physical qubit structure aimed at minimizing loss, microwave resonators for qubit readout and control, microwave drive lines to implement qubit rotations, couplers for generating multi-qubit interactions etc. Since superconducting qubits are artificially engineered, the designer also has a good control in targeting the desired circuit parameters such as the qubit's transition frequency and anharmonicity, resonator frequency, coupling strengths etc. 
 
In this Master thesis project, the student will design, simulate and characterize the various components of a multi-qubit device. The student will explore alternative designs for optimizing coupler structures for generating multi-qubit interactions. A major challenge to overcome would be to minimize crosstalk between the qubits which directly affects the fidelity of single- and two-qubit gates. 
 
We seek highly motivated students with a background in physics/electrical engineering/nanoscience. Knowledge about microwave circuit design and Python programming is highly appreciated. The student is expected to interact with other researchers focused on the subject at imec and communicate his/her progress effectively.
