Taming Rydberg Decay with Measurement-based Quantum Computation

Understand

Programmable neutral atom arrays show great promise for fault-tolerant quantum computing.

• A dominant physical error on this platform is qubit leakage and loss, notably decay errors from the Rydberg state during two-qubit gates.
• Such leakage events are particularly detrimental as they propagate, generating correlated errors that severely degrade the effective error distance of quantum error correction codes.
• Here, we present a novel approach to address Rydberg decay errors leveraging measurement-based quantum computation (MBQC).
