A3D3 Seminar: Atomic quantum processors and the error-correction frontier

Abstract: Quantum computers open new scientific avenues, from exploring complex quantum mechanical systems to new computational paradigms, but face the fundamental challenge of decoherence. Remarkably, decoherence can be prevented by creating highly entangled states of physical qubits that encode an error-corrected “logical” qubit. Here we will describe the development of quantum computing with reconfigurable arrays of neutral atoms and their use for quantum processing with logical qubits. Quantum processing in this approach is based on the coherent transport of atoms shuttled by optical tweezers, enabling any-to-any connectivity, high-fidelity programmable logic, and mid-circuit processing within a zoned architecture. Logical qubit processing is greatly facilitated by parallel control and transversal operations, and is used for experiments ranging from entangling logical qubits to their use for precise simulation of quantum scrambling. Core physical mechanisms for achieving deep-circuit, universal algorithms with logical qubits are identified, and these are leveraged into new techniques that greatly reduce overheads for large-scale computation. These results, alongside other recent advances, herald a transition to error-corrected quantum processing, establishing foundations that can enable future large-scale quantum computers and their useful applications. Dolev Bluvstein is a new faculty member in physics at the California Institute of Technology, working at the forefront of quantum information science. His research focuses on scalable quantum computing and quantum simulation using programmable arrays of neutral atoms, with an emphasis on high-fidelity control and quantum error correction. He has played a leading role in advancing neutral-atom platforms from fundamental many-body experiments to demonstrations of error-corrected quantum algorithms, and is widely regarded as one of the most promising young researchers driving the development of next-generation quantum processors.
