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

The U.S. government is committing up to $100 million each to D-Wave Quantum and Rigetti Computing, but the article frames this as a broad bet on quantum technologies rather than validation of either stock. Rigetti continues to face accuracy and scaling issues, including a delayed 108-qubit system and 99.1% 2-qubit gate fidelity versus a 99.5% target, while D-Wave remains stronger in annealing but has not yet proven its gate-based approach. The piece remains cautious on both names and prefers trapped-ion players such as IonQ and Quantinuum, which have reported 99.99% and 99.92% 2-qubit gate fidelity, respectively.

Analysis

The government capital looks more like an ecosystem subsidy than a stock-specific endorsement, which matters because it lowers existential financing risk for the sector without solving the core bottleneck: error rates. That creates a widening performance gap between architectures that are already close to fault-tolerant utility and those still fighting basic fidelity issues. In that context, capital is likely to concentrate over the next 6-18 months into names that can show measurable benchmark progress, not just headline quantum-qubit counts.

The second-order winner is IONQ. If procurement buyers and defense agencies decide to favor "works today" over "promises tomorrow," trapped-ion should attract disproportionate follow-on demand, partnerships, and talent migration. That dynamic can also pressure adjacent suppliers and software layers to align with the architecture most likely to commercialize first, rather than the one with the biggest narrative.

QBTS and RGTI remain funding-dependent story stocks, but the market may be underestimating how quickly a single missed milestone can re-rate them lower once subsidy headlines fade. RGTI looks especially vulnerable because the recent technical miss and DARPA setback weaken its credibility with both strategic buyers and public-market investors; QBTS has a better commercialization base, but its gate-model pivot reads like a long-dated option that still needs proof. The key reversal catalyst for both is not more funding, but verified fidelity improvement or a credible third-party benchmark that compresses the technology gap.

The contrarian read is that the government basket may have already absorbed the easy bullish argument. If investors had treated this as a blanket endorsement, the better trade is to fade the weakest architecture and own the leader with the clearest path to converting government interest into revenue and contracts. Over the next 3-12 months, the market should reward demonstrated technical progress over political symbolism.

Key Decisions for Investors

• Long IONQ vs short QBTS in a 3-6 month pair trade: thesis is that trapped-ion becomes the default beneficiary of government and defense validation, while QBTS remains a narrative-driven speculative name; target 15-25% relative outperformance with a stop if QBTS posts a major fidelity or revenue inflection.
• Reduce or avoid RGTI exposure into the next 1-2 quarters: the recent benchmark miss implies higher dilution and lower probability of near-term re-rating; if holding, hedge with out-of-the-money put spreads into technical update windows.
• Buy medium-dated IONQ call spreads (6-12 months): attractive asymmetric exposure if procurement/partnership flows accelerate; risk/reward improves if the market starts pricing architecture winners rather than sector-wide optionality.
• Use QBTS strength to sell covered calls or trim on government-related spikes: upside is capped unless the company can prove its dual-track gate-model roadmap, while downside remains meaningful if investors refocus on execution.
