Logical Quantum Processor Based on Reconfigurable Atom Arrays

Suppressing errors is one of the central challenges for useful quantum computing, requiring quantum error correction for large-scale processing. But the overhead in the realization of error-corrected “logical” qubits, where information is encoded across many physical qubits for redundancy, poses significant challenges to large-scale logical quantum computing. In this talk from the recent workshop on Advances in Quantum Coding Theory, Dolev Bluvstein (Harvard University) discusses recent advances in quantum information processing using dynamically reconfigurable arrays of neutral atoms, where physical qubits are encoded in long-lived hyperfine states and entangling operations are realized by coherent excitation into Rydberg states.
