Unlocking New Capabilities for Quantum Computation with Neutral Atom Arrays
Dr. Shai Tsesses
Abstract: 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 from key bottlenecks that constrain their operational speed and their implementation of deep quantum circuits. In this talk, I will show how my recent work can bend these constraints and sometimes completely break them. I will present results on accelerated detection of the atoms via high-lying energy states (Rydberg states) [5] and introduce novel protocols for reconfigurable multi-qubit gates [6], promoting improved circuit implementation speed for error correction. 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 [7]. 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.
Bio: Dr. Shai Tsesses is a postdoctoral associate at the MIT–Harvard Center for Ultracold Atoms, working with Prof. Vladan Vuletić. At MIT, he is leading a team developing the next generation of neutral atom quantum processors, able to implement deep and high-fidelity quantum circuits. Dr. Tsesses earned his Ph.D. in Electrical Engineering from the Technion–Israel Institute of Technology, where he made key experimental contributions to topological and quantum nano-photonics, as well as free-electron–light interactions. His research explores the frontiers of light–matter interaction, bridging atomic physics, electron beam physics, and quantum information science. He has authored more than 30 publications in leading journals such as Science and Nature, and is a recipient of numerous fellowships and awards, including the Rothschild and Adams Fellowships, as well as the OPTICA Tingye Li Innovation Prize.
