How will you contribute?

Join us for building the next generation of semiconductor quantum chips!

You will be part of the LIST Materials Research and Technology department, where you will carry out your work in the Quantum Materials Group, led by Dr. Florian Kaiser.

Within our ERC Consolidator Project “Q-Chip”, you will define the new standard in the scalability of solid-state quantum systems.

How? You benefit from the vast potential of our industry-compatible semiconductor quantum platform, i.e., colour centres in silicon carbide. You will integrate multiple electrical and optical control structures on a quantum chip, which unlocks completely new ways of operating quantum systems.

Your PhD thesis objectives include :

(a) Strongly increasing the quantum algorithm depth that we can implement with nuclear spin qubits in silicon carbide.

You will bring to live a novel concept that we have developed, which reduces two-qubit gate durations by at least one order of magnitude. This technique is unique to silicon carbide qubits and requires implementing high-speed magnetic field tuning lines at a nanoscale.

(b) Demonstrating the first scalable electro-optic quantum chip in silicon carbide based on parallelised nanoscale electric field tuning.

You will design and farbicate a quantum chip that incorporates Stark shift electrodes around several colour centres. This will allow you to make them operate at the same wavelength, a fundamental prerequisite for creating entanglement amongst them via photonic interference.

Additionally, you will demonstrate high-speed electro-optic switches on our silicon-carbide-strontium-titanate hybrid platform, which unlocks the ultimate scalability potential of the platform.

(c) The final goal is to combine the above techniques to create the first functional silicon carbide quantum chip, and to demonstrate its operation, e.g., creation of photon-mediated entanglement between distant nuclear spin qubits.

Overall, this PhD thesis project stands as a disruptive breakthrough towards cost-effective semiconductor-based quantum technologies.
