Project level: Honours

For quantum computing and simulation using neutral atoms trapped in a lattice one needs a physically scalable system that can facilitate single qubit initialization, gate and entanglement operations and state selective read-out.  The difficulty in constructing large-scale quantum processor is the need for strong qubit-qubit coupling, while maintaining weak coupling with the environment. Neutral, ultra-cold atoms trapped in lattice potentials have been proposed to be suitable system for quantum computing and simulation. Single magnetic quantum levels within the ground state hyperfine manifolds can serve as long-lived qubit states, and their weak coupling to the environment gives long coherence times.

For this project we will use a bottom-up approach for creating a 2D lattice with tens of lattice sites containing single atoms created by a time-averaged optical dipole trap suitable for relative large-scale quantum computing and simulation using dipole-dipole interactions and the Rydberg blockade. This setup will provide us with a versatile toolbox with single site addressability and selective, multi-site interaction for quantum computing and simulation purposes in a stroboscopic fashion.
