Researchers at Harvard University and QuEra Computing Inc. have made a significant breakthrough in error-corrected quantum computing.

They have built a logical quantum processor with up to 48 logical qubits, beating the previous record by more than 10 times.

The quantum processor uses reconfigurable atom arrays and color codes for fault-tolerant operations.

The team has shown the ability to perform multiple operations and correctly address errors.

This development indicates the potential for large-scale, fault-tolerant quantum computing.

This advancement is expected to lead the way for more powerful and practical quantum computers.
