Towards Josephson effect in fractional quantum Hall systems via light-matter interaction engineering

Project description

Unlocking topologically protected quantum computation

Condensed matter physics seeks to develop electronic phases that remain stable despite environmental disturbances, ultimately leading to the creation of systems that maintain quantum behaviours at macroscopic scales and under ambient conditions. Meanwhile, minor improvements to specific electronic phases could enable new hybrid platforms, opening up future functionalities. Supported by the Marie Skłodowska-Curie Actions programme, the SUPERFRACA project aims to establish the first Josephson junction for a fractional quantum Hall system by combining recent breakthroughs in light-matter physics and moiré materials. This research may also enable the production of specialised quasiparticles (parafermions), which could serve as essential building blocks for developing stable, large-scale quantum computers with topological protection.

Objective

One of the driving forces behind Condensed Matter physics research is the quest for electronic phases that are increasingly resilient to external perturbations, such as temperature fluctuations or disorder, with the long-term goal of achieving systems that exhibit quantum properties under ambient conditions and/or at the macroscopic scale. In the nearer term, even slight enhancements in the robustness of some specific phases could pave the way for novel hybrid platforms that combine fragile electronic states, potentially unlocking functionalities currently beyond our reach.
In this spirit, the SUPERFRACA project has been conceived to bridge recent advances in light-matter interaction physics and Moiré materials, with the ultimate goal of realizing the first-ever Josephson junction in a fractional quantum Hall system. Beyond the fundamental interest of bridging two of the most emblematic phenomena in Condensed Matter physics - namely the Josephson effect and fractional quantum Hall physics - this effort could also lead to the generation of novel quasiparticles, known as parafermions, which could serve as key components in the development of large-scale quantum processors based on topologically protected quantum computation.
