Electro-optical technologies for advanced control of quantum systems and quantum computers

PhD - Leuven | More than two weeks ago

An application-oriented research exploration on how electrically controlled optics might help to enable the emerging quantum technologies. 

What is limiting the upscaling of current quantum computing technologies? One might correctly point out to the maturity of the qubit and that this is question needs to be answered specifically individually for each quantum computer technology ranging from superconducting qubits over ion trapping to optical quantum computing. Yet there are other technologies that need to mature in parallel and among this are electro-optical devices. Contrary to qubits, a well-functioning electro-optic device technology finds application among all quantum computing technologies. For example, the optical readout of superconducting quantum computer requires the up-conversion of RF-photons to optical photons. Or optical and ion quantum computing require highly efficient EO-devices for entangling or routing photons via an electrically controlled high-speed optical switching network.
 
In this PhD, we will explore novel approaches to realize electro-optical devices and test their feasibility to enable the various quantum technologies. At the core of this investigations is the evaluation of novel electro-optical materials and how to integrate those into devices that need to be operated at cryogenic temperatures.
