量子運算股價預測：IonQ 43.91 美元，Rigetti 15.74 美元

把這四檔股票當成單一標的來做量子運算股價預測，這套邏輯經不起走勢圖的檢驗：從2025年12月31日收盤到2026年9月29日收盤，IonQ下跌2.1%，D-Wave Quantum下跌37.2%，中間相差35個百分點；而從8月28日至今，IonQ上漲12.0%，D-Wave卻下跌3.3%。個股報告從未把股價營收比與股價現金比放在同一頁比較，但這正是一籃子投資組合真正需要的對照。IonQ股價43.91美元，是其過去12個月2.46億美元營收的71倍；而Quantum Computing Inc.股價8.46美元，約為其最近公布現金水位的1.5倍。Rigetti股價15.74美元，是其最近公布5.41億美元現金的9.7倍，也約為其1,300萬美元營收的393倍。D-Wave股價16.43美元，是其5.46億美元現金的11.2倍，也約為其1,200萬美元營收的492倍。 這個分歧正是問題核心。IonQ的股價是以營收定價：其市值中約有155億美元是建立在公司自身備考現金數字之上的溢價。Quantum Computing Inc.則是以現金定價：把6月30日公布的約13億美元現金從19.1億美元市值中扣除，留給營運業務的只剩約6億美元。Rigetti的股價押注於一個物理與資金里程碑，而非其1,300萬美元的過去營收。D-Wave的股價則押注於一份尚未轉化為營收的系統合約，而其營收基數正在萎縮。若有交易台把「量子運算」當成單一走勢來買進，實際上是同時持有四種截然不同的標的多頭部位。 關鍵事實 2026年9月29日美東時間下午4點收盤價：IonQ 43.91美元、Rigetti 15.74美元、D-Wave 16.43美元、Quantum Computing Inc. 8.46美元。較2025年12月31日：分別下跌2.1%、28.9%、37.2%及17.5%。較8月28日：分別上漲12.0%、上漲1.0%、下跌3.3%、上漲3.8%。報價來自StockAnalysis，已與那斯達克收盤價交叉核對，擷取於2026年9月30日。 市值對過去營收比：IonQ市值174.5億美元，對應營收2.4647億美元（70.8倍）；Rigetti市值52.5億美元，對應營收1,335萬美元（393倍）；D-Wave市值61.2億美元，對應營收1,243萬美元（492倍，營收下滑44.2%）；Quantum...
