Quantum Information Processing with Atomically Thin Semiconductors

Project description

Atomically thin semiconductors for qubits on the fly

Quantum computers rely on qubits, which, unlike the binary 0s and 1s of conventional bits, can be in more than one state at the same time. They can be built from trapped ions, electrons, or even photons. To accomplish long-distance communication, stationary qubits must interact with so-called flying qubits in a way that does not degrade the quantum information they are carrying. To date, high-efficiency interfaces have been elusive. With the support of the Marie Skłodowska-Curie Actions programme, the QUIPATS project is developing a toolkit for the design of quantum optical interfaces based on atomically thin semiconductors, specifically transition metal dichalcogenides. This approach should accelerate advances in quantum computing and quantum simulation.

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.
