Unlocking New Capabilities for Quantum Computation with Neutral Atom Arrays

Neutral atom arrays have become a frontrunner in the race for utility scale quantum computation [1], building on their reconfigurability [2], scalability [3] and high fidelity for all operations [4] – idling, detection, single- and two-qubit gates. However, they still suffer key bottlenecks that constrain their operational speed, their deep quantum circuit implementation and gate fidelities. In this talk, I will show how my recent work can bend these constraints and sometimes completely break them. I will present my work on accelerated detection of the atoms via high-lying energy states (Rydberg states) [5] and introduce novel protocols for high-fidelity two-qubit gates [6] and reconfigurable multi-qubit gates [7], promoting improved circuit implementation speed and error rates. I will then update on our current progress in building a continuously operating neutral atom quantum processor, which mitigates the negative influences of atom loss, and present a new scheme we developed to operate atom array systems for this purpose [8]. Lastly, I will touch on the final frontier – how to increase system size to a utility scale number of qubits – and provide my own solution to it: free electron quantum interconnects between neutral atom quantum processing modules.
