Neutral atoms in tweezer arrays for hybrid Rydberg quantum computing

ORAL

Abstract

Our project aims to build a quantum co-processor for hybrid quantum computing, with online access via the Quantum Inspire platform of QuantumDelta NL. The co-processor is made of strontium atoms in a 2D optical tweezer array generated by a spatial light modulator. High-fidelity single-qubit control is achieved by laser coupling to the clock transition and for two- and multi-qubit gates using Rydberg excitations to control the interactions between different tweezer sites. The co-processor will be able to solve problems in quantum chemistry using pulsed-based quantum optimization algorithms. We report on the experimental progress and features of the new strontium machine. Furthermore, we discuss our approach to extend the scalability, addressability, and parallelizability of the number of qubits and qubit operations of the platform.
