An infidelity rate as low as one in ten thousand represents a marked improvement in generating entangled quantum states using superconducting circuits. Previously, digitally preparing such Bell pairs typically resulted in error rates around one in a thousand, demanding approximately 80 to 130 nanoseconds for completion. This new analogue protocol achieves comparable fidelity within similar timescales, offering an alternative route beyond standard digital methods.
