סמינר בחומר מעובה: Unlocking New Capabilities for Quantum Computation and Simulation 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. They have also produced large scale quantum simulation of complex many-body systems [5]. However, they still suffer key bottlenecks that constrain their operational speed, their deep quantum circuit implementation and the range of physical models thye are able to simulate. 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) [6] and introduce novel protocols for reconfigurable multi-qubit gates [7], promoting improved circuit implementation speed and error rates. I will show how arbitrary spin-spin interaction models can be implemented in atom arrays through Floquet engineering [8], extending their ability to simulate many important quantum magnetism models. 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 [9]. 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.
