As quantum computing advances, post-quantum cryptography is rapidly moving from niche research topic to a core pillar of long-term cybersecurity planning for governments and enterprises.
Report overview and strategic context
The new “Post-Quantum Cryptography” market study, published today, on Feb. 23, 2026, by ResearchAndMarkets.com in Dublin, analyzes how quantum-safe cryptography is reshaping digital trust architectures for the coming quantum era. It maps the transition from vulnerable legacy encryption to resilient security across cloud, network, hardware, and identity ecosystems.
According to the report, post-quantum cryptography is evolving from theoretical research into a critical component of next-generation cybersecurity. Advances in quantum computing threaten the foundations of classical schemes such as RSA and elliptic curve cryptography, which underpin digital identity, secure communications, and long-term data protection worldwide.
Moreover, the study warns that harvest-now, decrypt-later strategies are escalating risk exposure for data with multi-decade lifecycles. As a result, governments, financial institutions, telecom operators, and cloud providers are accelerating quantum-safe transitions to protect sensitive information, critical infrastructure, and long-lived trust systems.
Standards and regulation driving quantum-safe migration
Standards-led progress is now anchoring PQC adoption. The National Institute of Standards and Technology (NIST) has approved lattice-based and hash-based algorithms, including ML-KEM, ML-DSA, SLH-DSA, and Falcon, establishing a global baseline for quantum-resilient encryption and authentication across industries.
These post-quantum standards enable software-based deployment on existing infrastructure, support hybrid cryptographic modes that combine classical and quantum-safe schemes, and provide a practical migration path for enterprises. However, regulatory and policy mandates from bodies such as the NSA, ETSI, and the IETF are equally important, embedding PQC into national security systems, telecom frameworks, and core internet protocols.
That said, the report notes that organizations must treat quantum-safe transition as an ongoing capability rather than a one-off upgrade. Crypto-agility is emerging as the dominant architectural principle, allowing systems to swap algorithms as standards evolve and new vulnerabilities or performance constraints appear.
Momentum in PQC adoption and key use cases
Momentum in adoption is strongest in sectors that manage high-value data with long retention requirements. Financial services, government, defense, and telecom are leading pilots and early deployments, integrating quantum-safe cryptography into TLS, VPNs, identity systems, cloud key management, firmware signing, and secure messaging platforms.
Cloud hyperscalers, browser vendors, hardware security module providers, and chipmakers are converging to operationalize PQC across software stacks, protocols, and hardware trust anchors. Moreover, constrained environments such as IoT, automotive, and industrial systems are emerging as priority frontiers for PQC-enabled hardware, device identity, and secure modules, given their long in-field lifetimes.
The report underscores that post quantum cryptography algorithms are now appearing in live environments rather than just in testbeds. This shift marks a turning point from speculative preparation toward measurable impact on production networks and applications.
From experimentation to production deployment
PQC is moving decisively beyond laboratory validation and proof-of-concept trials. Live implementations now secure quantum-safe email authentication, zero-trust access, satellite communications, banking networks, and enterprise VPNs, delivering operational, standards-compliant protection across critical infrastructure.
Cloud key management services, certificate authorities, and firmware and software signing workflows are also beginning to integrate quantum-resilient primitives. However, adoption remains uneven due to performance overheads, legacy integration complexity, limited tooling, and skills shortages, as well as ongoing uncertainty around the exact timeline for large-scale quantum computers.
That said, the report emphasizes that organizations cannot afford to wait for definitive quantum timelines. Long-lived data, especially in finance, healthcare, and government, must be shielded today to avoid future decryption once quantum attackers become feasible.
Investment, innovation, and market dynamics
Investment and innovation signals point to a rapidly maturing market. Deal activity intensified through 2024 and remained resilient into 2025, supported by venture funding, acquisitions, and strategic partnerships across cybersecurity vendors, quantum software companies, and cryptographic infrastructure providers.
Patent filings peaked in 2024, reflecting sustained R&D in lattice-based schemes, secure networking, and crypto-agility frameworks. Moreover, hiring trends show expanding demand for quantum-resilient security expertise across cybersecurity, cloud, and semiconductor ecosystems, indicating that PQC skills are becoming a core requirement for modern security teams.
According to the study, this wave of investment is not merely defensive. Many players view quantum-safe security as a source of competitive differentiation, product innovation, and regulatory alignment, especially in highly regulated industries and critical national infrastructure.
Industry leaders and ecosystem convergence
The report profiles initiatives from a broad set of technology and financial leaders embedding PQC into commercial platforms. Featured companies include Apple, AROBS Polska, Bank for International Settlements, BTQ Technologies, Chase, China Telecom, Cloudflare, the European Space Agency, and the European Telecommunications Standards Institute.
Other highlighted participants are Google, Honeywell, J.P. Morgan, Microsoft, NVIDIA, Nokia, Numana, NXP Semiconductors, OpenSSL, Orange Business, SEALSQ, Signal, Singtel, Smart Banner Hub, ST Engineering, TELUS, Thales, and Toshiba. Together, they illustrate how cloud providers, telecom operators, chipmakers, and specialist cryptography firms are converging around common standards.
Moreover, these companies are helping the market migrate from vulnerable RSA and elliptic curve systems to resilient, standards-compliant foundations across software, protocols, and hardware. Their commercial platforms are increasingly expected to offer quantum-safe options as default for new deployments.
Sector-specific adoption and innovation trajectories
The study explores sector-specific paths for PQC rollout, focusing on industries with long-lived data and infrastructure. Financial services, government, defense, and telecom currently lead early deployments, particularly for secure communications, transaction processing, and identity management systems.
At the same time, automotive, aerospace, industrial systems, and IoT are identified as critical growth areas for PQC-enabled hardware, device identity, and secure communications. However, constrained computing and connectivity in these environments pose design challenges, requiring careful optimization of algorithm choice, key sizes, and protocol overhead.
That said, the report views these constraints as opportunities for innovation, especially around lightweight implementations, hardware acceleration, and flexible key management tailored to embedded systems and edge devices.
Barriers, enablers, and strategic outlook
The analysis details several barriers to large-scale PQC rollout, including performance overheads, complex integration with legacy systems, limited interoperability tooling, and acute skills shortages. These hurdles slow uniform adoption, particularly for smaller organizations and highly customized infrastructures.
However, the report also identifies strong enablers of scale, such as regulatory mandates, standards finalization, cloud and platform readiness, and rising awareness of harvest-now, decrypt-later risks. Long-term data protection requirements across industries further reinforce the urgency of transitioning to quantum-safe architectures over the coming years.
In its strategic outlook, the study concludes that PQC is shifting from theoretical necessity to foundational security infrastructure. It argues that crypto-agile, standards-led designs will underpin digital trust across cloud, networks, devices, and data ecosystems as quantum capabilities mature.
Guidance for decision-makers
The report offers strategic recommendations to help CISOs, security architects, technology leaders, policymakers, and investors plan their response. It urges organizations to design structured migration strategies, prioritize high-risk systems and long-lifecycle assets, and align security architectures with evolving standards and regulatory expectations.
Moreover, decision-makers are encouraged to treat PQC as part of a broader modernization of identity, key management, and network security rather than a standalone upgrade. This integrated approach supports better risk management and allows enterprises to benefit from innovations in zero-trust models and secure cloud infrastructure.
As quantum-safe cryptography becomes central to secure communications, digital identity, cloud infrastructure, and critical systems, the Innovation Radar report provides the strategic intelligence needed to navigate a rapidly maturing landscape and maintain digital trust in the quantum era.
