August 2024: Interested in joining the Quantum Fluids research team? We are hiring a PDRA to work on the K-Rb quantum-mixture experiment currently under development. The experiment will ultimately be used to explore vortex dynamics in binary superfluids. See https://bit.ly/QuantumMixturesPDRA or contact Dr Kali Wilson for more details.
The conference for Quantum, Atomic and Molecular Physics 2023 (QuAMP 2023) takes place at Strathclyde University.
We studied the stability of a Bosonic quantum gas in a 1D optical lattice with periodic driving, Phys. Rev. Research 5, 033024 (2023).
Congratulations to Dr Jonathan Pritchard on receiving a prestigious RAEng Senior Research Fellowship with M Squared Lasers to develop fault-tolerant neutral atom quantum computers. For more information see the project page QuERy.

We have demonstrated high-fidelity randomised benchmarking of single qubit microwave gates across an array of 225 atoms, and non-destructive readout of up to 49 atoms. We achieved an average gate error of 8×10-5 which is below the threshold for fault tolerant operations, highlighting the viability of neutral atoms for scalable computing. For more details see our paper Phys. Rev. Lett. 131, 030602 (2023) [arXiv].
We have demonstrated the UK’s first neutral atom two-qubit gate using a novel protocol based on electromagnetically induced transparency originally proposed back in 2008. We achieve a corrected CNOT gate fidelity of 0.82(6), mainly limited by available laser power. For more details see Phys. Rev. Lett. 129, 200501 (2022).

We have developed a robust protocol for implementing high-fidelity multiqubit controlled phase gates (CkZ) on neutral atom qubits coupled to highly excited Rydberg states via adiabatic rapid passage (ARP). We find a CCZ gate with fidelity F > 0.995 for three qubits and CCCZ with F > 0.99 for four qubits is attainable in ∼ 1.8 μs via this protocol. For more details see our paper in QST.
