CISA and G7 Cyber Security Working Group Partners Release Post-Quantum Era = Call to Action [ https://www.cisa.gov/resources-tools/resources/preparing-p= ost-quantum-era-call-action?utm_source=3DG7PQEraCalltoAction&utm_medium=3DG= ovDelivery ] 09/03/2026 11:00 AM EST=20

Today, the Cybersecurity and Infrastructure Security Agency (CISA) and Grou=
p of Seven (G7) Cyber Security Working Group members released Preparing for=
the Post-Quantum Era: A Call to Action highlighting the urgent need for or= ganizations and governments to begin transitioning to post-quantum cryptogr= aphy (PQC) to protect sensitive data and critical assets from emerging quan= tum computing threats.

Unlike traditional computers that process data in binary digits or =E2=80= =9Cbits=E2=80=9D which have only one of two possible values, quantum comput= ers use quantum bits or =E2=80=9Cqubits=E2=80=9D which can exist in a combi= nation of both values at the same time=E2=80=94making it possible for quant=
um computers to problem-solve faster than traditional computers. As quantum=
computing advances, these computers will be able to break public-key crypt= ography widely used to protect sensitive data and communications.

Malicious cyber threat actors are already intercepting and storing public-k=
ey encrypted data today in =E2=80=9Charvest now, decrypt later=E2=80=9D str= ategies. Once cryptographically relevant quantum computers (CRQCs) are avai= lable to malicious cyber threat actors, they will be able to target organiz= ations still using public-key encryption with the potential to impersonate = trusted entities, compromise equipment, and access confidential data.

This call to action urges organizations not to wait for CRQCs to become ava= ilable, but to prioritize PQC migration and begin identifying critical asse= ts, mapping dependencies, and developing phased transition plans aligned wi=
th their national cybersecurity authorities. Read the call to action [ http= s://www.cisa.gov/resources-tools/resources/preparing-post-quantum-era-call-= action?utm_source=3DG7PQEraCalltoAction&utm_medium=3DGovDelivery ] to learn=
more about PCQ migration and the five priority areas to consider when plan= ning.
