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.
Rydberg Atom Array Quantum Simulator
Summary Quantum simulators enable probing the static and dynamic properties of correlated quantum many-body systems that would otherwise be numerically inaccessible using classical simulators. We are developing quantum simulators based on arrays of neutral atoms excited to Rydberg states. Such Rydberg atom arrays are advantageous for simulating the dynamics of interacting spin systems (Ising spin […]

Free-space Polarization-selective Microcavity based on Chiral Metasurfaces
Summary Developing a new type of Fabry-Pérot cavity that allows improved control of the atoms’ emission into the cavity mode will result in enhancement of the efficiency and fidelity of quantum state transfer from photons to atoms and back. This in turn can be used to improve the performance of quantum networks and repeaters, as […]
