Our **ReQFlow** achieves **state-of-the-art (SOTA)** performance 🎯 in protein backbone generation while requiring significantly fewer sampling steps and substantially reducing inference time. For example, it is **37×** faster than RFDiffusion and **62×** faster than Genie2 when generating a backbone of length 300, demonstrating both its effectiveness and efficiency 🚀🚀🔥.
