The timing appears calculated. Quantum computing stocks have gained momentum throughout 2025, and major tech companies from IBM to Google continue expanding their quantum research divisions. For businesses watching from the sidelines, the question isn't whether quantum will matter – it's when and how quickly they need to adapt.
Phasecraft's Quantum Advantage Play
Founded in 2019 by Toby Cubitt, Ashley Montanaro and John Morton, Phasecraft represents a different approach to quantum commercialization. Rather than building quantum hardware, the Bristol-based company focuses on developing algorithms that extract maximum performance from today's imperfect quantum machines.
The $34 million Series B round, co-led by Plural, Playground Global and Novo Holdings' Quantum Fund, brings Phasecraft's total funding to over $50 million including grant money. What makes this significant isn't just the amount – it's the strategic positioning.
Current quantum computers suffer from what researchers call "noise" – errors that creep into calculations. Most companies are working to build better hardware. Phasecraft takes a software-first approach, designing algorithms that work despite these limitations.
The company has already secured partnerships with the UK's National Energy System Operator, BT, and Johnson Matthey. These aren't research collaborations – they're working relationships with companies that need quantum solutions for real business problems.
"Quantum advantage" remains the industry's holy grail – the moment when quantum computers outperform classical machines on commercially relevant tasks. Phasecraft's bet is that smart algorithms will reach this threshold before perfect hardware becomes available.
New Mexico's $315 Million Quantum Gamble
While Phasecraft represents private sector momentum, New Mexico's quantum initiative showcases how governments view quantum technology as strategic infrastructure. The $315 million package includes $185 million from the state's sovereign wealth fund for venture capital investments, plus infrastructure spending and a partnership with DARPA.
Governor Michelle Lujan Grisham told Reuters that New Mexico leverages its historical connections to atomic research – the state houses Los Alamos National Laboratory and Sandia National Laboratories. This isn't starting from zero.
The initiative includes several components designed to create a complete quantum ecosystem:
Venture Capital Fund: $185 million for direct investments in quantum companies Infrastructure: Funding for fabrication facilities and quantum networking equipment DARPA Partnership: Up to $120 million in matching federal contributions over four years Research Network: A statewide quantum network connecting labs and businesses
The project directly supports DARPA's Quantum Benchmarking Initiative (QBI), suggesting coordination between state and federal quantum strategies.

The Business Case Takes Shape
These investments reflect growing confidence that quantum computing will generate real returns. But the timeline remains unclear, and businesses need to understand what applications appear most promising.
Financial services leads early adoption. Quantum computers excel at optimization problems – exactly what banks need for portfolio management and risk analysis. Insurance companies are exploring quantum algorithms for pricing models that account for complex risk correlations.
Logistics and supply chain optimization represent another near-term opportunity. Companies like UPS and FedEx handle routing problems that grow exponentially complex as variables increase. Quantum algorithms could optimize delivery routes in ways classical computers cannot match.
Drug discovery offers perhaps the most compelling long-term case. Pharmaceutical companies spend billions on molecular simulation. Quantum computers naturally model quantum mechanical systems, potentially accelerating drug development timelines.
Manufacturing and materials science also benefit from quantum simulation capabilities. Companies developing new materials or optimizing chemical processes could see significant advantages.
Market Forces and Competition
The quantum computing market faces several competing dynamics. Hardware companies like IBM, Google, and IonQ focus on building more stable quantum processors. Software companies like Phasecraft bet that clever algorithms can overcome hardware limitations. Meanwhile, cloud providers offer quantum computing as a service, making the technology accessible without massive capital investments.
China continues heavy quantum research investment, creating geopolitical pressure for Western nations to maintain technological leadership. The Biden administration's quantum initiatives, combined with state-level programs like New Mexico's, suggest quantum technology has become a national security priority.
Corporate venture capital also flows toward quantum startups. Major consulting firms now offer quantum strategy services, indicating enterprise interest in understanding potential applications.
Preparing for Quantum Reality
For business leaders, quantum computing presents both opportunity and risk. Companies that identify viable applications early could gain significant competitive advantages. Those that ignore quantum developments might find themselves at a permanent disadvantage.
The key is separating realistic near-term applications from longer-term possibilities. Quantum computing won't replace classical computers – it will solve specific problems that classical machines handle poorly.
Businesses should identify optimization challenges within their operations. Supply chain routing, financial portfolio optimization, and resource allocation problems could benefit from quantum algorithms sooner than more exotic applications.
Partnership strategies also matter. Rather than building internal quantum capabilities, most companies will likely access quantum computing through cloud services or partnerships with specialists like Phasecraft.

Investment Implications
The $349 million committed in early September represents just a fraction of total quantum investment. McKinsey estimates quantum computing could generate $850 billion in annual value by 2040, but near-term revenue opportunities appear more modest.
Investors face the classic emerging technology dilemma: quantum computing clearly offers immense potential, but identifying winners requires technical expertise and patience. The hardware vs. software divide adds complexity – will algorithm companies like Phasecraft capture more value than hardware builders?
Public market quantum stocks remain volatile, influenced more by announcements than revenue. Private quantum companies continue raising capital at high valuations, but few demonstrate clear paths to profitability.
The New Mexico initiative represents a different investment approach – using public funds to build an entire ecosystem rather than betting on individual companies. This patient capital approach may prove more effective for nurturing quantum commercialization.
Investment Flow Analysis: Where the Money Goes
The September funding surge reflects broader investment patterns that reveal how capital flows through the quantum ecosystem. Recent analysis shows that quantum investment has become increasingly diversified across sectors, with distinct preferences emerging between government and private funding sources.
Across all quantum-related companies, 37% are focused on quantum hardware components, 15% on software, and 15% on quantum communications and security. This breakdown helps explain why Phasecraft's software-focused approach attracted significant private investment, while New Mexico's infrastructure-heavy initiative required government backing.
Governments are currently the largest purchasers of quantum communication technologies, at approximately 57 percent of all purchases in 2024, but the private sector is increasingly adopting the technology. The data suggests that as quantum applications mature, private sector adoption will accelerate dramatically.
