Quantum Computing Stocks: How the Quantum Computing Players Stack Up by Patents (Yes, Nvidia Has Such Patents)

Quantum computing is nascent but projected by BCG to expand from about $1.4bn in 2024 to $90–170bn by 2040 (roughly a 30–35% CAGR), making intellectual property a key signal of future leadership; patent tracking complements but does not replace traditional financial due diligence, especially cash and burn metrics. U.S. entities dominated 2024 U.S. quantum patents with IBM (117 patents) and Alphabet (63) materially ahead of peers; among pure plays Rigetti led 2024 awards while D-Wave has a larger overall patent stock and the highest average forward citations (25.3), followed by Northrop Grumman (21.2) and Rigetti (13.0). Nvidia recorded three U.S. quantum patents in 2024 and is pursuing hybrid quantum-classical workflows via NVQLink to tie quantum processors to GPU AI supercomputers, signaling likely growing involvement. The data imply IP leadership and citation strength as useful indicators of technological positioning and potential moats, but investors should weigh these alongside liquidity and commercial progress.

Analysis

BCG projects the global quantum computing market to expand from roughly $1.4 billion in 2024 to $90–170 billion by 2040, implying a ~30–35% CAGR with much of the value accruing later in the period; this underscores that quantum computing is nascent and commercialization timelines remain uncertain. The article highlights U.S. dominance in 2024 U.S. quantum patents with IBM (117 patents) and Alphabet (63) materially ahead of peers, while Microsoft (21) lagged in patent awards during the year and Rigetti led among pure plays with 19 patents in 2024. Nvidia recorded three U.S. quantum patents in 2024 and introduced NVQLink to connect quantum processors with GPU-based AI supercomputers, signaling strategic moves toward hybrid quantum-classical systems. Patent quality metrics show D-Wave with the highest average forward citations (25.3), followed by Northrop Grumman (21.2) and Rigetti (13.0), implying that citation-weighted IP strength complements raw patent counts; the article emphasizes that patent activity should be used alongside liquidity metrics such as cash on the balance sheet, cash flow and cash burn when evaluating investment prospects.

Key Decisions for Investors

• Prioritize names that pair scale in patent filings with citation-weighted quality (IBM 117 patents, Alphabet 63, D-Wave 25.3 average forward citations) but require corroborating evidence of commercialization before increasing exposure
• Do not rely solely on annual patent counts for pure-play allocations; require transparent liquidity metrics (cash, cash flow, burn) and near-term revenue or partnership milestones for IonQ, Rigetti and D-Wave before adding material risk
• Monitor Nvidia's patent activity and NVQLink adoption as a potential signal to increase exposure to hybrid quantum-classical plays if 2025 updates show accelerating product integration and strategic commitment
