量子计算概念股的市场狂热正在上演。以Rigetti和D-Wave为首的公司，在几乎没有收入和实际应用的情况下，股价于12个月内一度暴涨1900%，市值 突破百亿美元。这一现象引发了市场关于"下一个颠覆性技术"与"投机泡沫"的激烈辩论。 以Rigetti Computing Inc.和D-Wave Quantum Inc.为代表的量子计算公司，在过去12个月里股价一度飙升超过1900%，表现远超许多热门人工智能股 票，成为市场中最具争议的投机热点。 这一惊人涨幅使两家公司的市值双双突破100亿美元，甚至远超AI明星公司Palantir，也超过了金宝汤公司(Campbell's Co.)等老牌企业。然而，它们目 前几乎没有实际应用，且预计未来数年都无法产生可观收入，现金消耗巨大。 市场对此看法两极分化。多头认为，量子计算有望解决从疾病治疗到气候变化等重大问题，是不容错过的下一个颠覆性技术。而空头则警告称，这只是 一个由投机情绪驱动、缺乏基本面支撑的泡沫，注定将会破灭。 在人工智能热潮之后，资本市场正将目光投向量子计算这一更具想象空间的领域。 泡沫担忧并非空穴来风。据彭博汇编数据，Rigetti的估值超过其远期销售 ...
