1、Page 1 GAO-25-107703 Quantum Cybersecurity Strategy Federal agencies and our nations critical infrastructuresuch as energy,transportation systems,communications,and financial servicesare dependent on technology systems and electronic data to provide essential services and to process,maintain,and rep

2、ort vital information.Agencies and critical infrastructure owners and operators rely on cryptography(e.g.,encryption)to protect sensitive systems and data.However,the emergence of quantum computers could undermine the security of widely used cryptographic methods.Some experts predict that a quantum

3、computer capable of breaking certain cryptographyreferred to as a cryptographically relevant quantum computer(CRQC)may be developed in the next 10 to 20 years,putting agency and critical infrastructure systems that rely on cryptography for security at risk.Furthermore,adversaries could copy data pro
