Preparing for Q-Day: New Executive Orders Address Quantum Innovation and Post-Quantum Cryptography

On June 22, 2026, President Donald Trump signed two executive orders aimed at accelerating quantum technology innovation and fortifying national cybersecurity against future quantum threats. The orders establish the Quantum Computer for Application Development and Discovery Science (QC-ADDS) initiative and mandate the federal adoption of post-quantum cryptography (PQC). These actions signal a strategic shift in the National Quantum Strategy toward the immediate deployment and commercialization of quantum assets to maintain national security and economic competitiveness.

The first executive order, “Ushering in the Next Frontier of Quantum Innovation,” establishes the QC-ADDS effort to coordinate federal agencies in the development of a scientifically useful quantum computer by 2028. This initiative seeks to solve complex problems beyond classical computing capabilities while expanding infrastructure for quantum sensing and networking, which are viewed as critical to national security. For the quantum ecosystem, including hardware and software developers, this signals a move from long-term research toward federal support for commercialization and advanced infrastructure investment.

The second order, “Securing the Nation Against Advanced Cryptographic Attacks,” addresses the cybersecurity risks of “Q-Day” by directing agencies to adopt PQC standards approved by the National Institute of Standards and Technology (NIST). This directive specifically targets the “harvest now, decrypt later” threat, where adversaries collect encrypted data today to decrypt it once quantum capabilities mature. To facilitate this transition, the Cybersecurity and Infrastructure Security Agency (CISA) will release guidance on a “cryptographic bill of materials,” requiring vendors to document the cryptographic components within their hardware and software products.

These executive orders carry significant implications for federal contractors and operators of critical infrastructure in sectors such as energy, finance, and defense. Organizations should expect new procurement requirements involving quantum-readiness assessments and adherence to updated Federal Information Processing Standards (FIPS). As the federal government expands its investment in quantum-secure communications and semiconductors, private sector entities are encouraged to incorporate quantum risk into their broader enterprise risk-management frameworks to prepare for future compliance and capitalize on emerging funding opportunities.
