标题： Harvesting magic from the vacuum

摘要： 魔法是一种量子资源，使量子计算机能够执行经典计算无法高效模拟的操作。 因此，在量子系统中生成魔法对于实现量子优势至关重要。 这封信表明，通过与初始真空态的量子场相互作用的三能级 Unruh-DeWitt探测器（一个三重态）可以收集魔法。 虽然从量子场论（QFT）中提取资源的想法源于纠缠的收集，但我们的结果将该协议扩展为使三重态从非魔法状态演变为魔法状态，从而可能从QFT中生成魔法。 显示英文摘要

摘要： Magic is the quantum resource allowing a quantum computer to perform operations that cannot be simulated efficiently by classical computation. As such, generating magic in a quantum system is crucial for achieving quantum advantage. This letter shows that magic can be harvested by a three-level Unruh-DeWitt detector (a qutrit) interacting with a quantum field in an initial vacuum state. While the idea of extracting resources from Quantum Field Theories (QFT) was born from the harvesting of entanglement, our result extends the protocol to evolve a qutrit from a non-magical state to a magical one, making it possible to generate magic from QFT.
