The post-quantum cryptography market was valued at $356.4 million in 2023 and is expected to grow at a CAGR of 41.47%, reaching $17,696.4 million by 2034. The market is driven by the rising need to secure digital infrastructure against quantum computing threats, leading to advancements in cryptographic algorithms. With the rise of quantum computing, a seismic shift in cybersecurity is underway. Quantum computers promise to solve complex calculations at unprecedented speeds, posing significant threats to traditional encryption methods. As quantum computing technology matures, the need for new cryptographic solutions—known as post-quantum cryptography (PQC)—is becoming urgent.

Introduction of Post-Quantum Cryptography

The study conducted by BIS Research defines post-quantum cryptography as the development of encryption techniques designed to resist threats posed by quantum computing. Post-quantum cryptography focuses on creating algorithms capable of securing digital data even against quantum attacks, which have the potential to break traditional cryptographic systems. This field is critical for protecting sensitive information in areas such as finance, healthcare, and national security. By leveraging new cryptographic algorithms, advanced mathematical theories, and continuous R&D efforts, post-quantum cryptography offers enhanced resilience for digital infrastructure, enabling organizations to safeguard their data and communications against the future risks of quantum-powered decryption.

Quantum computers leverage the principles of quantum mechanics, such as superposition and entanglement, to perform calculations beyond the reach of classical computers. This power enables quantum computers to break widely-used encryption standards, like RSA and ECC (Elliptic Curve Cryptography), which are foundational to internet security today. Without new cryptographic techniques, everything from personal data to national security could be at risk.

Post-quantum cryptography is the solution to this threat. It involves developing new cryptographic algorithms that are resilient to attacks by quantum computers. The global post-quantum cryptography market is emerging quickly, with stakeholders across industries preparing to integrate these solutions.

Key Drivers of the PQC Market

Quantum Computing Advancements

Quantum computing is progressing rapidly, with tech giants like Google, IBM, and startups like Rigetti pushing the boundaries. As quantum computing moves closer to achieving "quantum supremacy," the urgency for robust PQC solutions grows. This rising threat fuels investments in PQC R&D, creating a booming market.

Government Regulations and Initiatives

Governments worldwide are recognizing the quantum threat. For instance, the U.S. National Institute of Standards and Technology (NIST) is in the process of standardizing quantum-resistant cryptographic algorithms. Such governmental mandates increase demand for PQC solutions across sectors like finance, defense, and healthcare, where data security is critical.

High-Stakes Industries Demand

Sectors like finance, healthcare, energy, and national defense hold sensitive information and are prime targets for cyberattacks. These industries are increasingly investing in post-quantum solutions, given the potential fallout of compromised data. As a result, the PQC market is poised for steady growth, especially in high-stakes industries.

Growing Awareness of Long-Term Data Security Risks

Hackers can intercept and store encrypted data today with the intention of decrypting it once quantum computers become powerful enough. This “store now, decrypt later” risk is pushing organizations to adopt PQC sooner rather than later. As organizations start considering long-term data security, they are turning to post-quantum cryptography to future-proof their systems.

North America Region to Dominate the Global Post-Quantum Cryptography Market (by Region)

North America is leading the post-quantum cryptography (PQC) market due to several key factors, including substantial government backing, corporate investment, and early adoption of quantum technologies. The U.S. government, through agencies such as the National Institute of Standards and Technology (NIST), has been at the forefront of PQC standardization. NIST's PQC competition has driven global research and development, establishing the U.S. as a leader in quantum-safe algorithms that can resist future quantum threats. Additionally, strong regulatory frameworks and initiatives such as CISA’s Quantum Readiness program ensure that critical infrastructure and government systems transition to quantum-safe encryption well ahead of time. Furthermore, North American tech giants such as IBM, Google, Microsoft, and Intel are heavily investing in the research and commercialization of PQC technologies. These companies not only contribute to NIST's standardization process but also deploy quantum-safe cryptography solutions in their cloud services, telecommunication systems, and enterprise security offerings. The region's well-established tech ecosystem, coupled with venture capital investments, provides fertile ground for PQC innovation and adoption
