The aim of the work is to develop theoretical tools to simulate and predict the behaviour of a one-dimensional chain of trapped dipolar molecules and to study the nature of entanglement as a design resource. In this device, individual water molecules are trapped inside C60 fullerene cages (also known as buckyballs), which in turn are inserted into a carbon nanotube. Such a peapod-like structure can be created using recent advances in organic synthesis. Remarkably, the quantum level structure of the guest molecule in the carbon nanotube peapod remains nearly identical to a free molecule, which makes this system a promising platform for implementing quantum information protocols, comparable to those explored with atoms and molecules trapped in optical lattices. Along the way, we are working to understand the response of the device to external electromagnetic fields, which could open the door to its use for precision electric field sensing with potential capabilities to detect fields from a single molecule.
Distributing Multimode Entanglement with Microwave Photons
Microwaves have enabled numerous classical technologies, in part because they propagate through air with little energy loss.

On-Chip Microwave-Optical Quantum Interface
Summary In this project we develop a quantum interface between microwave and optical photons as a key enabling technology of a hybrid quantum network. In such a network, the robust optical photons carry quantum information through optical fibres over long distances, while superconducting microwave circuits protected from thermal photon noise by the low temperature […]

Silicon Platform for Electron Spin Qubits
Summary Scaling solid-state quantum processors to a useful threshold while maintaining the requisite precision in quantum control remains a challenge. We propose a quantum metal-oxide-semiconductor (QMOS) architecture operating at cryogenic temperatures that is based on a network/node approach as a means to scalability. By working with QMOS, we benefit from the deep investments and […]
