On-Chip Quantum photonics technology holds the promises to deploy quantum effects into compact devices that can be produced and applied at scale, contributing to next generation quantum computing and communication industry. Various material platforms are currently studied, however, none of them retains the scalability, robustness to nanofabrication processing and environmental operating conditions in combination with all the required intrinsic quantum properties of their qubits.
Silicon carbide (SiC) is an industrially mature semiconductor, when produced in high purity single crystal wafer it can be used to develop high quality qubits with optical interface in the telecom band. Other approach is silicon carbide (SiC) on insulator (SiCOI). The SiC has CMOS compatibility and fabrication process scalability, controllable p and n-doping, capable of integrated opto-electronic device and photonic components fabrication.
The SiC can respond to the urgent needs of scaling and advances in harnessing quantum effects towards higher technology readiness and manufacturing sustainability using wafer scale SiC. Its current crystal growth matureness has reached “quantum grade” readiness, signifying that qubits can be engineered and can be integrated into nanophotonic. This provides an increased technology readiness for the quantum technology industry and an alignment with the technology sustainability standpoint.
Key open challenges are to scale the SiCOI technology to a wider industrial level and to transfer the research lab photonics fabrication processes to quantum device manufacturing. There are today few research players and industries worldwide. There it is an opportunity to act jointly by global exchange to facilitate the technology readiness in a faster way.
Prof. Stefania Castelletto, RMIT, Australia will share plans to establish spin and optical qubits in planar integrated photonic chip SiCOI for quantum computing, quantum communication and quantum sensing. The introduction will be followed by a view by Dr Alexey Lyasota, UNSW, Australia, from young researcher perspective for research and career. After that there is an open discussion on shared prospects and possible exchange and collaboration.
