Quantum Information Processing with Atomically Thin Semiconductors
Quantum technologies have the potential to transform modern communication and information processing. Quantum technologies make use of the laws of quantum mechanics to improve over technologies based on classical physics that we experience in everyday life. Two important examples are quantum key distribution and quantum computation: The former enables provably secure communication while the latter can solve certain hard problems that are intractable with conventional computers. Despite tremendous recent progress, the commercialization of quantum technologies remains in its infancy. The key challenge is to protect the extremely fragile quantum states from detrimental noise. There exist many competing platforms aiming to overcome this hurdle, each with its own strengths and weaknesses. In the project QUIPATS, I explored how two-dimensional semiconductors may address some limitations of current approaches. Two-dimensional semiconductors are materials composed of one or few layers of atoms. They interact strongly with light, which renders them promising candidates for interfaces that receive, manipulate, and transmit quantum information. The objectives of QUIPATS were to develop software and theoretical tools to model the optical properties of two-dimensional semiconductors. These tools were then applied to design novel optical devices in collaboration with experimental researchers at Harvard University. The findings highlight the promise of two-dimensional semiconductors for a wide range of quantum technological applications.

Project objective
Quantum technologies promise to revolutionise modern communication and information processing. A key bottleneck in building large-scale quantum computers and networks is the current lack of high-efficiency interfaces between stationary and travelling qubits (photons). Atomically thin semiconductors such as monolayers of transition metal dichalcogenides (TMDs) have the potential of greatly simplifying the design of such interfaces and enabling novel devices that are unavailable with state-of-the-art techniques. In this project, I propose the development of a toolkit for emerging quantum optical interfaces based on TMDs. The toolkit includes a software package to model the photonic properties of devices involving two-dimensional materials. In addition, I will refine the theoretical description of the quantum many-body states of optical excitations in doped TMDs, which is essential to accurately predict the performance of quantum optical interfaces. I will demonstrate the power of these tools by proposing experimentally realizable devices with applications in quantum communication and quantum simulation. Moreover, the proposal encompasses several activities aimed to refine my communication and leadership skills. In particular, I will establish an outreach programme with a local high school to raise awareness of the transformative potential of quantum technologies and to generate excitement about scientific research. Considered in its entirety, the proposed activities will enable me to become a fully independent researcher and scientific leader while contributing meaningfully to a highly active area of research.
