PhD projects:
1) Integration of tunable photon sources into photonic quantum processors
The low rate at which photonic qubits are produced and inserted into integrated photonic circuits designed to perform quantum computing and simulation is one of the main bottlenecks for advancing this form of quantum information processing. In this project, we will attack this problem by developing sources embedded in chips, so that the number of photons that can be used to encode qubits is much higher than what is possible to obtain today, even using the best commercially available sources.
What will you do in this project?
- Learn about quantum information processing using photonic qubits,
- Learn about methods of tuning single photon emitters using mechanical deformations,
- Work with electromagnetism and mechanics simulations,
- Perform optical characterizations of semiconductor materials, using Raman spectroscopy, micro-photoluminescence and photon correlation,
- Manufacture photonic devices, using modern micro and nano manufacturing techniques.
National and international collaborations:
We will use materials grown by the group Prof. Armando Rastelli, from Johannes Kepler University, in Linz, Austria. In Brazil, this project will be developed in collaboration with Prof. Christoph Deneke, from IFGW, and Dr. Ingrid Barcelos, from CNPEM/Sirius. In 2024 we will have the participation of Dr. Saimon Covre, who is carrying out a post-doctorate in our laboratory.
Scholarship complementation:
During the project, we will submit funding requests to, among others, supplement the value of your scholarship. The complementation will depend on the approval of the projects and their good academic and scientific performance.
2) Development of modular and reconfigurable architecture of photonic processors
In order for photonic processing of quantum information to reach a scale where it is possible to begin to address interesting problems, beyond simple proofs of concept, it is necessary for processors to have a significant increase in the number of qubits they can receive and process. In order to achieve this growth without overloading the classical systems used to control the processor, it is necessary to answer a series of questions that are still open about how to organize the basic elements that act on the qubits.
We intend to explore different architectural possibilities for photonic circuits with the aim of finding designs that are modular, so that blocks with different functions can be freely chained and reorganized, and reconfigurable, so that each block can have its function adjusted depending on the specific task it will be executed.
