Investors are advised to adopt a balanced approach by selecting established tech companies and pure plays. Three recommended stocks include Alphabet, which is investing heavily in quantum technology; IonQ, known for its unique trapped ion technology; and Nvidia, which is adapting its software for quantum computing. While these stocks carry risks, they also present significant upside potential, making them attractive options for investors looking to enter the quantum computing market. Quantum computing stocks are starting to pick up steam again. After a summer largely spent moving sideways, many of the tech niche's pure plays have been putting up noteworthy gains in September. However, all of these stocks are still quite risky as investments, as there's no guarantee that their approaches to quantum computing will pan out commercially. With that in mind, if you're looking to invest in quantum computing technology, I'd suggest taking a balanced approach, picking some established tech players that are pursuing it to extend their offerings as well as some pure plays that offer greater potential rewards to go with their higher risks. Adding these three companies to your portfolio would exemplify this balanced approach, and I think that, as a group, this trio will beat the market over the next five years.

In December, Alphabet unveiled its Willow quantum computing chip, touting its impressive early achievements. That helped kick off a massive investment rush in the quantum computing sector. If Alphabet can develop a commercially viable quantum computing approach, it could have significant implications for its business. Right now, when Alphabet needs more processing power to support its internal artificial intelligence models or to rent out via its cloud computing arm, it must buy enormous quantities of chips from companies like **Nvidia** (NVDA 0.35%). This is quite expensive, and a large fraction of the money Alphabet pays for this hardware is the sellers' profit. If Alphabet can develop a viable quantum computer in-house to boost its AI capabilities and rent out via Google Cloud, its profit margins will soar. Most companies that choose to make use of quantum computing will likely access it primarily via a cloud service, likely through a hybrid approach that combines traditional computing methods with quantum technology. In addition to boosting Alphabet's own margins, if it can bring commercially viable quantum computing to the masses, it could attain first-mover advantage and win numerous contracts to run workloads on its servers. However, even if Alphabet's quantum computing technology flops, it will still have its dominant digital ad business to fall back on. This makes Alphabet a much safer investment in the quantum computing industry, at least compared to some of the start-ups. ## IonQ **IonQ** (IONQ -6.00%) isn't a safe stock. It must achieve relevancy with its quantum computing product, or the stock could go to $0. That's a huge amount of risk, but the stock also has immense upside potential if its technology pans out. IonQ is taking a different approach to quantum computing than most of its competition. Its trapped ion technology trades speed for accuracy. Currently, IonQ's quantum computers hold the world record for one-qubit (99.999%) and two-qubit (99.97%) gate fidelity. This is a common metric that quantum computing companies use to measure the number of errors their machines make in the course of processing data. If it can deliver the most accurate technology, IonQ may be able to carve out a durable niche for itself before others can bring rival products to market. Time will tell if IonQ will be a successful quantum computing investment, but it's taking an unusual approach that offers massive advantages, so I like its chances. ## Nvidia **Nvidia** (NVDA 0.35%) may not seem like a quantum computing investment at first glance. It's largely focused on traditional computing with its high-end graphics processing units (GPUs). However, Nvidia isn't blind to the future and is working on facilitating a hybrid computing approach. That will likely be how most quantum computers are eventually deployed. When the AI trend kicked off, many onlookers focused on the fact that Nvidia had the best hardware to support AI workloads. But a less obvious advantage for the company was that its software platform for programming its chips was undoubtedly the best available, too. The popularity of its CUDA platform with developers helped Nvidia to capture massive market share in the AI processor space -- a lead that it has maintained to this day. Now, with quantum computing on the horizon, Nvidia has adopted its platform with a version designed for quantum computing: CUDA-Q. By offering a version of its already popular software that helps developers integrate quantum computers into their existing infrastructure, Nvidia will secure its place in another major computing trend. Furthermore, there's still huge demand for AI processing power, so Nvidia will likely remain a highly profitable company well into the future based on that alone. This makes Nvidia a great stock to buy and hold, as it bridges the gap between traditional and quantum computing methods. Even if its quantum computing efforts fail to deliver, its established strengths mean decreased risk for its shareholders. ### Related Stocks - [NVDA.US - NVIDIA](https://longbridge.com/en/quote/NVDA.US.md) - [GOOGL.US - Alphabet](https://longbridge.com/en/quote/GOOGL.US.md) - [IONQ.US - IonQ](https://longbridge.com/en/quote/IONQ.US.md) - [GGLS.US - Direxion Daily Googl Bear 1x Shares](https://longbridge.com/en/quote/GGLS.US.md) - [GGLL.US - Direxion Daily GOOGL Bull 2X Shares](https://longbridge.com/en/quote/GGLL.US.md) - [NVDL.US - GraniteShares 2x Long NVDA Daily ETF](https://longbridge.com/en/quote/NVDL.US.md) - [07788.HK - XL2CSOPNVDA](https://longbridge.com/en/quote/07788.HK.md) - [07388.HK - XI2CSOPNVDA](https://longbridge.com/en/quote/07388.HK.md) - [NVDY.US - YieldMax NVDA Option Income Strategy ETF](https://longbridge.com/en/quote/NVDY.US.md) - [NVDD.US - Direxion Daily NVDA Bear 1X ETF](https://longbridge.com/en/quote/NVDD.US.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 谷歌高层回应 AI 泡沫质疑：这是工业革命，但速度快 10 倍、规模大 10 倍 | 谷歌 CEO 在印度 AI 峰会上透露谷歌云积压订单已翻倍至 2400 亿美元，以此证明高额资本开支的合理性。DeepMind CEO 预测实现通用人工智能至少仍需 5-10 年。谷歌高层一致认为，AI 将从根本上改变中小企业和科学研究的工 | [Link](https://longbridge.com/en/news/276440500.md) | | 谷歌突然发布 Gemini 3.1 Pro：核心推理性能直接翻倍 | 谷歌发布了最新的大模型 Gemini 3.1 Pro，其推理性能较去年发布的 Gemini 3 Pro 翻倍。在 ARC-AGI-2 评测中，Gemini 3.1 Pro 得分 77.1%，显示出强大的推理能力。新模型支持多源数据综合和复杂 | [Link](https://longbridge.com/en/news/276396515.md) | | 传言成真？英伟达对 OpenAI 的 “1000 亿美元投资” 最终 “打了三折” | 据报道，英伟达正接近敲定对 OpenAI 最高 300 亿美元的股权投资，取代此前官宣的 1000 亿美元合作框架。原有协议因条款分歧与内部疑虑未能落地，黄仁勋亦曾强调其不具约束力。此次新融资轮规模或超 1000 亿美元，OpenAI 估值 | [Link](https://longbridge.com/en/news/276507066.md) | | 学习英伟达刺激芯片销售，AMD 为 “AI 云” 借款做担保 | AMD 为扩大市场份额祭出金融 “狠招”！为初创公司 Crusoe 的 3 亿美元购芯贷款提供担保，承诺在其无客户时 “兜底” 租用芯片。这一复刻英伟达 “租卡云” 路径的策略虽能短期推高销量，但也令 AMD 在 AI 需求放缓时面临更大的 | [Link](https://longbridge.com/en/news/276401504.md) | | 都想学英伟达 “芯片换融资”，谷歌和 AMD 都要扶持 “AI 云” | 谷歌正试图复制英伟达的成功路径，利用金融实力构建芯片生态系统。公司正洽谈向 “新型云” 公司 Fluidstack 注资约 1 亿美元，并为 Hut 8 等转型矿企提供项目融资支持，以换取 TPU 芯片的采用。AMD 则更为激进，为初创公司 | [Link](https://longbridge.com/en/news/276502552.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
