Researchers have developed a novel feedforward architecture that enhances the coherence cloning of ultra-narrow-linewidth lasers, a crucial component in quantum control and precision metrology1. By mitigating the effects of feedback latency, this approach enables high-bandwidth coherence cloning, overcoming a significant limitation of traditional optical phase locking techniques. The new architecture achieves this by recycling a portion of the signal, allowing for more efficient phase noise suppression. This breakthrough has significant implications for quantum computing and precision metrology applications, where ultra-stable laser sources are essential. The ability to clone coherence at high frequencies enables more accurate control and measurement, paving the way for advancements in quantum technology. So what matters to practitioners is that this innovation can potentially accelerate the development of quantum computing and cryptography, ultimately rewriting the assumptions about computation and data security.
