Investors already holding IonQ (NYSE: IONQ) shares may want to spread their exposure across multiple quantum computing companies as the sector accelerates toward commercialization.
IonQ reported a $1.87 billion loss in the second quarter but posted revenue of $80.1 million, representing a staggering 287% year-over-year increase.
The market has largely looked past IonQ’s losses, focusing instead on the long-term potential of quantum computing as a transformational technology over the next decade.
Rigetti Computing (NASDAQ: RGTI) is one of the most government-backed quantum companies in the sector, having received $100 million in CHIPS Act funding that also gave the U.S. government an equity stake.
That government ownership creates a built-in incentive for continued public support of Rigetti, even as the company reported a $28.1 million operating loss on just $5.1 million in Q2 revenue.
According to Rigetti’s August 2026 investor presentation, the quantum industry could generate up to $850 billion in economic value by 2040, signaling massive runway for early-stage players.
Rigetti’s customer list includes Amazon (NASDAQ: AMZN), Microsoft (NASDAQ: MSFT), financial institutions, and government agencies such as NASA, providing a diverse and prestigious commercial pipeline.
Infleqtion (NYSE: INFQ) is another quantum company with strong government ties, recently securing $20 million from NASA to support the world’s first quantum gravity mission, which aims to deploy a space-based quantum gravity sensor.
Infleqtion also holds a long-term partnership with Nvidia (NASDAQ: NVDA) to integrate quantum capabilities into AI data centers, a hybrid approach the company argues requires less capital and maximizes facility efficiency.
Infleqtion Chief Technology Officer Pranav Gokhale described the company’s neutral atom technology as the superior choice due to “its inherent scalability,” underlining its competitive positioning in the race toward widespread quantum adoption.
D-Wave Quantum (NASDAQ: QBTS) combines quantum hardware and software on a dual-platform architecture and reported a 1,120% year-over-year increase in first-half bookings, with $35.5 million now sitting in its pipeline.
Fortune 2,000 companies accounted for 47.7% of D-Wave’s total revenue in the second quarter, reflecting a meaningful shift toward commercial adoption among large enterprise customers.
D-Wave published a research paper in Nature detailing breakthroughs in fault-tolerant gate-model quantum computing, citing dual-rail cavity qubits as “an attractive path for achieving fault-tolerant quantum computing.”
The company’s experiments showed that dual-rail qubits can achieve low error rates while maintaining a favorable error hierarchy, making mistakes easier to detect and correct in real-world applications.
Across all three companies, traditional valuation metrics like price-to-earnings ratios remain largely irrelevant, and investors are better served evaluating what these businesses could look like five to ten years from now.
