Description du sujet de thèse

The development of quantum information technologies requires the interconnection of different quantum systems having specific tasks (processing, memory), such as microwave qubits platforms. Photons in the near-infrared allow for such efficient transfer of quantum information, preserving the non-classical state over long distances. The conversion of quantum information between microwave photons and optical photons is therefore a key step that this project aims to achieve.
The objective of this project is therefore to design a device to demonstrate the conversion of classical and then quantum signals between these two spectral domains. This on-chip converter will consist of a superconducting microwave resonator and an optical resonator, both interacting with a mechanical mode that will mediate the conversion. With these converters, we will then aim to generate entanglement between distant microwave qubits.
