Recently, the research team led by Yang Zhicheng of Peking University's School of Physics has achieved a significant breakthrough. Their findings indicate that quantum entanglement can serve as an efficient conduit for infusing quantum "magic"—more formally known as quantum non-stabilizerness—into quantum systems. This breakthrough enables a more efficient extraction of "magic" resources from quantum gates. Through rigorous model verification, the study has shown that the greater the initial degree of entanglement within a quantum system, the more "magic" resources can be injected, establishing a clear linear relationship between the two variables. Furthermore, the research revealed that pre-existing quantum entanglement can render the effects of dispersed injection comparable to those of global injection. This phenomenon, driven by the mechanism of quantum gate teleportation, markedly enhances the efficiency of resource utilization. Additionally, the research team introduced a novel physical quantity—the unitary stabilizer Rényi entropy—to more accurately quantify the "magic" content of quantum gates. These findings have been published in npj Quantum Information.
