Atomic quantum processors and the error-correction frontier
Quantum computers open new scientific avenues for exploring complex quantum mechanical systems, ranging from entangled matter to the underlying fabric of spacetime, 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. In this talk I will present experimental studies of error-corrected quantum processing using reconfigurable arrays of neutral atoms. Experiments range from entangling logical qubits to their use for precise simulation of quantum scrambling, and demonstrate new techniques that greatly reduce overheads for large-scale computation. Finally, I will discuss routes toward large-scale computation with next-generation processors, and the new science they may enable.
