Background for this topic.
Quantum computing uses quantum-mechanical effects in qubits to solve some problems differently from conventional computers. In information security, its significance is primarily cryptographic: a sufficiently capable, fault-tolerant quantum computer could use Shor’s algorithm to break RSA and elliptic-curve cryptography, which protect certificates, key exchanges, signatures, and encrypted archives. Quantum computing is not expected to break all cryptography equally; symmetric encryption and cryptographic hashes generally require larger security parameters rather than replacement for the same reason.
The practical concern is “harvest now, decrypt later”: adversaries can collect encrypted traffic today for future decryption, especially when data must remain confidential for years. Organizations should inventory public-key algorithms and long-lived sensitive data, assess dependencies such as certificates and protocols, and plan migration to standardized post-quantum cryptography with crypto-agile systems. Quantum key distribution is a separate, specialized communications approach; it does not replace endpoint security, authentication, or conventional key-management controls and has significant deployment constraints.

Strong Data Foundations Give AI Leaders an Edge in Quantum SecurityCompanies leading in AI security are also better prepared for quantum threats. New Thales research shows that data visibility, governance, encryption and crypto agility are helping CIOs build stronger foundations for both AI adoption and post-quantum readiness.
Experts Detail Migration Scope, Timelines and Governance Gaps in Going Quantum-SafeMigrating to post-quantum cryptography isn't a weekend patch. It's one of the largest transformations an enterprise will undertake, and it will require a multi-year program spanning infrastructure, vendors, governance and policy, according to a panel of experts.
Agencies and Industry Coordinate Post-Quantum Migration PlansThe White House convened government officials, quantum companies and researchers to accelerate the transition to post-quantum cryptography, align public-private investments and reinforce a 2030 deadline as advances in quantum computing increase risks to today's encryption.
Microsoft on Tuesday said it's accelerating its quantum safe security roadmap, stating technology advances in quantum computing are making it essential to replace existing encryption standards sooner than previously expected
Microsoft has brought forward its timelines for transitioning to post-quantum cryptography (PQC)
Microsoft announced today that it is accelerating its quantum-safe security roadmap, saying advances in quantum computing are bringing the need to replace today's encryption standards sooner than previously expected. [...]
Today’s encrypted data, such as credentials, may no longer remain confidential in the future because the public-key cryptography protecting it will soon be broken by quantum computers. Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by
With federal PQC deadlines set for 2030 and 2031, CISOs face a multi-year transformation program that most organizations have not yet started. The window for orderly execution is narrowing fast. The post What the post-quantum executive order really demands of CISOs appeared first on CyberScoop.
Getting accurate visibility into IT and OT systems will be compounded by multivendor environments, misaligned update life cycles, and interoperability gaps.
President Trump signed an executive order on June 22 setting hard deadlines for federal agencies to move high-value assets and high-impact systems to post-quantum cryptography
All US federal agencies will have to complete their post-quantum cryptography transition by 2031, according to a new Trump Executive Order
Healthcare organizations should prepare for post-quantum cryptography without overreacting to hype, said John Frushour, CISO of New York-Presbyterian Hospital. Stronger encryption standards, commercial software support and attention to medical devices can help providers manage emerging risks.
Bank of Ireland's Francis Gorman Shares Strategies for Successful Quantum MigrationMost organizations give the migration to quantum-safe cryptography to the CISO. But that puts a cross-business change in the wrong hands. Accountability belongs with senior leaders who can influence the whole enterprise, says Francis Gorman, head of Bank of Ireland's security center of excellence.
It May Already Be Too Late, Says AtheneThe transition to post-quantum cryptography will be a heavy lift. Experts from Germany's National Research Center for Applied Cybersecurity say there's plenty that can be done in the short term to prepare for a world in which classical cryptography is no longer able to protect secrets.

IBM, Google and Other Firms Are Focusing on Commercial Value as Quantum ProgressesIBM's $10 billion quantum computing push reflects a broader industry effort to move beyond scientific milestones and toward business value. But cybersecurity leaders say vendors should focus less on product narratives and more on meaningful progress.
GCHQ director urges urgent business cyber action as AI and quantum reshape the threat
GCHQ Director Says Quantum Computing Is Coming, Downplays Tech SovereigntyA top British intelligence official touted a "blueprint" for cybersecurity defense that leans into AI agents for speed. "We all have an intergenerational duty to harness and secure it for good; to protect our national security, our economy and our way of life," said GCHQ Director Anne Keast-Butler.
