【遇事不决，量子力学】有没有人考虑投quantum computing的？【 XNDU割韭菜了】

I would use two rankings , because “best investment” depends on whether you want risk-adjusted exposure or direct pure-play upside . #p-8028090-a-best-risk-adjusted-public-quantum-investments-1A. Best risk-adjusted public quantum investments IBM — best mix of real quantum operating presence, full-stack control, and non-binary downside protection. IBM already has broad platform access, a large network, and a credible roadmap, so you are not paying purely for hope. IonQ — best direct public pure-play. It has by far the strongest 2025 revenue among the pure-plays, large cash reserves, broad cloud distribution, and a more complete platform story than just “one hardware bet.” Microsoft — very strong risk-adjusted optionality because Azure can monetize the ecosystem even before Microsoft’s own hardware wins; Majorana 1 gives it real upside if topological qubits work. NVIDIA — not a quantum pure-play, but one of the most plausible winners if the sector remains hybrid for many years. CUDA-Q and the new Ising models position NVIDIA as infrastructure rather than a single-modality bet. Honeywell — best hidden-asset play because you get indirect ownership of Quantinuum without taking single-company quantum startup risk. The planned IPO path is the key catalyst. D-Wave — strongest smaller-name commercialization case today, especially in optimization and hybrid workflows, but annealing is a narrower thesis than general fault-tolerant QC. Amazon — good platform toll-collector, but quantum is still a small piece of the AMZN thesis. Alphabet — world-class quantum R&D, but the stock is still mostly an AI/search/cloud advertising investment rather than a clean quantum vehicle. Infleqtion — attractive neutral-atom and government/sensing mix, but the story is less purely “quantum computing platform” than IonQ or IBM. Xanadu — the most interesting public photonics name, but still very early and newly public. Rigetti — credible superconducting technology and improving systems, but commercial scale still trails IonQ and D-Wave. QUBT — too speculative for me as a core holding given the current revenue base. #p-8028090-b-best-direct-public-pure-play-quantum-stocks-2B. Best direct public pure-play quantum stocks IonQ (IONQ) D-Wave (QBTS) Infleqtion (INFQ) Xanadu (XNDU) Rigetti (RGTI) Quantum Computing Inc. (QUBT) That order reflects how I would weight commercial traction , balance-sheet strength , platform breadth , and technology credibility today. IonQ leads on scale and capital, D-Wave on near-term enterprise deployment, Infleqtion on neutral-atom plus software/sensing breadth, Xanadu on photonics optionality, Rigetti on superconducting progress, and QUBT remains the most speculative relative to present commercialization. #p-8028090-what-i-would-do-3What I would do If I were investing in quantum today , I would not make it a single-stock bet. I would treat the space as a barbell : Core exposure: IBM, Microsoft, NVIDIA, and Honeywell for lower-risk participation in the buildout. These names can still win even if the eventual hardware winner is someone else. Direct upside: IonQ as the main pure-play position, with a smaller allocation to D-Wave. Speculative satellites only: Infleqtion and Xanadu if you want neutral-atom and photonics exposure; Rigetti only if you specifically want a superconducting-chiplet bet; QUBT only as a high-risk flyer. In plain English: IBM is my best overall public quantum name today, and IonQ is my best pure-play quantum stock today.

不懂不投

最近量子天天跌

我现在稍微定投一点点 放到退休，亏了就亏了

今天xndu 怎么了 能买还是能卖了

增发股票割韭菜了 六七家公司一起买的，别的好像都没怎么动，行业还在，继续买吧 Shares in Xanadu Quantum Technologies ( https://research.investors.com/quote.aspx?symbol=XNDU ) plunged on Monday after the company filing to register nearly 294 million shares for resale in a move related to its merger with Crane Harbor Acquisition Corp . ( https://research.investors.com/quote.aspx?symbol=CHAC ), a special purpose acquisition company. With today’s retreat, Xanadu stock is still up 36% in 2026 amid volatile trading. SPACs, also called blank-check vehicles, raise money in an initial public offering with the purpose of purchasing companies. The newly registered shares, which will dilute existing equity, come from insider conversions, private placements, founder shares, and legacy shareholders.
