Better Quantum Computing Stock to Buy: IonQ vs. Rigetti

IonQ emerges as the superior quantum computing pure-play stock compared to Rigetti Computing, leveraging its trapped-ion technology that achieves 99.99% 2-qubit gate fidelity and generating significantly higher revenue ($65M in Q1 vs. Rigetti's $4.4M). While both companies pursue different quantum computing approaches, IonQ's superior accuracy, greater computational capacity, and stronger market traction position it as the better investment, though diversification through quantum computing ETFs is recommended given sector risks.

Is Rigetti Computing Stock a Buy Right Now?

Rigetti Computing's stock has fallen from an October 2025 all-time high of $58 to around $21, raising questions about its investment potential. The quantum computing company received up to $100 million in U.S. government funding and tripled Q1 2026 revenue to $4.4 million, but remains unprofitable with significant operating losses. With $400+ million in cash, Rigetti has runway to develop commercially viable quantum applications, though success depends on long-term market adoption and faces intense competition from pure-play quantum companies and tech giants like Google and IBM.

Xanadu Quantum vs. IonQ: The Better Quantum Computing Stock Buy for 2026

The article compares two quantum computing companies: Xanadu Quantum Technologies, a newly public photonic quantum computing company, and IonQ, which uses ion-based technology. While both show strong revenue growth, IonQ is recommended as the better investment due to significantly higher sales ($64.7M vs $2.8M in Q1), larger cash reserves ($3.1B vs $272.5M), and a more attractive valuation (P/S ratio of 98 vs 700). IonQ's technology has gained more market traction and it has assembled a comprehensive technology stack positioning it for sustained growth.

3 Quantum Computing Stocks Down Sharply -- but 1 Offers Exceptional Value

Quantum computing stocks have experienced a valuation reset after a strong rally in April-May. While Rigetti Computing and IonQ show impressive technology and growth, their valuations appear stretched. D-Wave Quantum stands out as offering better value with strong booking momentum, major enterprise contracts, and a more reasonable valuation that may underestimate its commercial potential.

Why IonQ Stock Ended This Week in the Green Despite Early Sell-Offs

IonQ stock recovered from a double-digit decline early in the week to finish with a 2.6% gain, outperforming the S&P 500 and Nasdaq. The recovery was driven by news of a preliminary U.S.-Iran peace deal framework, which eased geopolitical tensions and inflation concerns. Lower energy prices and reduced interest rate hike expectations could benefit AI stocks like IonQ going forward.

IonQ, Rigetti, and D-Wave Are Surging Again. Is Quantum Computing Finally Real?

Quantum computing stocks IonQ, Rigetti, and D-Wave have surged 50%+ since late March following a $2 billion federal investment announcement. However, the author cautions that useful quantum computing remains a decade or more away, and these stocks trade at extreme valuations with no profits, making them highly vulnerable to market sentiment shifts.

Google Rejects Quantum Funding Over Government Equity Strings

Google declined a $2 billion federal quantum computing grant due to conditions requiring government equity stakes, which would have slowed research timelines. The rejection divides the quantum sector into two camps: funded companies (IBM, GlobalFoundries, Rigetti, D-Wave, Infleqtion) gaining government validation and infrastructure, versus unfunded tech giants (Google, Microsoft, IONQ) retaining autonomy. IBM targets its first scalable quantum system by 2029, while Google's Willow chip demonstrates quantum advantage through independent development.

Is The Newest Quantum Stock IPO a Buy?

Quantinuum, a quantum computing company formed from Honeywell's quantum division and Cambridge Quantum, went public at $60 but now trades around $51. Despite securing $100 million in government funding, the company faces challenges including a sky-high valuation of 463x sales, widening losses ($192.6M in 2025), and concentrated revenue from a single lease. Analysts suggest it's less attractive than competitor IonQ, which has faster growth and a lower valuation multiple.

After Receiving $100 Million in Government Funding, Are Rigetti Computing and D-Wave Quantum the Best Quantum Computing Stocks?

The U.S. government invested up to $100 million each in quantum computing companies Rigetti Computing and D-Wave Quantum as part of a diversified bet on different quantum technologies. However, the analyst cautions that this government investment should not be viewed as validation of these specific stocks. Rigetti faces accuracy challenges with its superconducting approach, while D-Wave leads in annealing technology but has yet to prove its dual-rail qubit architecture claims. The analyst prefers trapped-ion technology companies like IonQ and Quantinuum due to their superior accuracy metrics.

Why Did IonQ Stock Bounce Back Today?

IonQ stock rebounded 10.5% after a 21.2% crash the previous week driven by broader market concerns rather than company-specific bad news. The sell-off was triggered by Broadcom's warning on AI chip sales and a strong employment report that reduced expectations for Federal Reserve rate cuts. While IonQ has sufficient cash currently, the company faces long-term pressure from high interest rates as it burns through ~$900 million in cash over the next few years and remains unprofitable.

Quantinuum Stock Opens Above IPO Price, Then Fades

Quantinuum (QNT) debuted on NASDAQ with a 13% pop above its $60 IPO price, opening at $68, but quickly faded to around $62 as sellers stepped in. The quantum computing company raised $1.68 billion from the IPO with 20x oversubscription. However, with 2025 revenue of only $30.9 million against a $192.6 million net loss, the stock's decline from intraday highs reflects investor concerns about the company's burn rate. The IPO sparked a sector rotation, with most quantum computing peers declining.

IonQ is the First Pure-Play Quantum Computing Company To Generate Over $100 Million in Revenue. Is the Stock Headed to $100?

IonQ has become the first pure-play quantum computing company to exceed $100 million in annual revenue, growing from $2 million in 2021 to $130 million in 2025. While the company's trapped-ion technology and government contracts show promise with projected 70% CAGR through 2028, analyst Leo Sun argues the stock is unlikely to reach $100 this year due to rich valuations (40x 2028 sales), continued unprofitability, shareholder dilution, and insider selling outpacing buying.
