Quantum error correction with global control
Researchers have proposed a quantum error correction scheme that uses global control fields, potentially simplifying the control electronics required for large-scale quantum processors.

This could allow near-term quantum processors with limited control resources to implement error correction, accelerating demonstrations of logical qubits.
Global control is already available in neutral atom and trapped ion systems; if the proposed codes can be verified experimentally within two years, it could reduce the hardware overhead for error correction.
