From: Enhancing the yield of bucket brigade quantum random access memory using redundancy repair

Simulated yield (left y-axis) and number of physical qubits in the qRAM construction (right y-axis) versus number of logical qubits in qRAMs with different degrees of quantum error correction (QEC). The fabrication error rate was fixed at 0.5%. RR(8) denotes using eight spare qubits for redundant repair.
