量子隐形传态在光学频域取得了显著进展，但面临持续挑战，包括高传输损耗和有限的透射率。相比之下，微波频域具有独特优势，如降低吸收损耗、能耗较低以及与超导量子技术的兼容性。为克服光学量子隐形传态的局限性，本研究提出了一种适用于室温开放空气环境的基于微波的连续变量量子隐形传态（CVQT）方案。所提方法采用微波双模压缩态，并通过量子剪裁操作增强纠缠以缓解环境退化。数值模拟表明，室温下微波纠缠态用于CVQT的最大传输距离约为200米。结果还表明，在相似天气条件下，微波CVQT方案在短距离上相较于光学频域CVQT具有更低的衰减和更高的保真度。此外，微波量子态对天气引起的波动表现出较低的敏感性，突显了其鲁棒性及在开放空气量子通信应用中的实用性。
