PhD research on Integrated Electro-optical devices for quantum conversion

PhD - Leuven | More than two weeks ago

An application-oriented research to explore the limits of Electro-optical device technologies ultimately asking: Can single RF photons be converted to the optical domain?

Quantum information technology promises unique possibilities for Science and Society (Secure communication, Resource Optimization, or Molecular Drug Design). Yet, enabling this technology is a monumental task, which requires a large variety of technological advancement to enable low-cost chip-scale quantum technologies. For instance, cryogenic quantum computing based on superconducting circuits requires large amounts of electrical interconnects between the room temperature control electronics and the millikelvin superconducting/solid-state quantum chip. This puts a heavy burden on the scaling cost of such systems. Optical interconnects are envisioned to help overcome this limitation, but the question– if electro-optical devices are sensitive enough to provide a true quantum gateway between superconducting and optical qubits – remains?
In the framework of your PhD we will investigate the ultimate limits of electro-optic and explore concepts to bridge the five order of magnitude energy gap between the superconducting (GHz) and optical (100s of THz) qubits. These concepts require the exploration of new device architectures, innovative approaches in nanotechnology and advanced materials.
The research environment provides unique opportunities for your personal and professional development as it bridges from exploitative academic research to application-oriented engineering.


Required background: Masters in Physics or Electrical Engineering. Experience in Photonics and/or Superconducting Circuits/Qubits is an asset. Experience in Nanotechnology fabrication is an asset.


Type of work: 60% Experiments (Technology & Characterization), 20% Theory, 20% Modeling
