Quantum computing is becoming a serious legal, cybersecurity, and business risk-management issue. Although practical quantum computers capable of defeating widely used cryptographic systems are not known to exist today, businesses should not wait until the risk becomes immediate before planning for it. The migration from existing cryptographic systems to quantum-resistant systems may take years, and in some cases the risk already exists because sensitive encrypted data can be collected now and decrypted later when stronger quantum capabilities become available.
For companies that store confidential information, process personal information, use cloud services, rely on digital signatures, operate e-commerce platforms, manage intellectual property, or maintain regulated data, quantum computing should be part of the cybersecurity and legal compliance conversation. This includes businesses subject to privacy laws, cybersecurity requirements, vendor-management obligations, data retention duties, contractual security commitments, and regulatory oversight.
