Quantum Error Correction in a dual species Rydberg Array (QuERy)
The QuERy project is focused on development of a dual-species platform for neutral atom quantum computing to address the major barriers to scaling existing platforms from 100s to thousands of qubits, namely extending atom array trapping lifetimes through integration in a cryogenic environment and enabling active error correction through the ability to perform cross-talk free, state-selective local measurements.

Scalable Qubit Arrays for Quantum Computation and Optimisation
This project will utilise the advanced SQuAre neutral atom quantum computing platform developed at Strathclyde, offering up to 225 qubits. The aim is to perform pioneering demonstrations of small-scale digital and analogue algorithms relevant for addressing industrially relevant real-world problems relating to optimisation as well as studies of many-body quantum systems.

Quantum Error Correction (QuERy)
This project, supported by a Royal Academy of Engineering Senior Research Fellowship and M Squared Lasers, seeks to develop a new experiment focused on creating dual-species arrays of Cs and Rb for quantum error correction. This is integrated within a 4K closed-cycle cryostat to obtain extended trap lifetime for scaling to large numbers of qubits, and will focus on exploiting long-range dipole interactions between Rydberg states of each species to enable mid-circuit, non-destructive readout and generation of topologically protected logical qubits as a route towards fault tolerant digital quantum computing.
