Definition ∞ The Quantum Era refers to a future period when quantum computing technologies become sufficiently advanced to perform calculations that are intractable for even the most powerful classical supercomputers. This period will likely witness a profound transformation across various fields, including cryptography, materials science, and drug discovery. The advent of stable, scalable quantum computers could disrupt current cryptographic standards, necessitating new security protocols. It signifies a fundamental shift in computational capabilities.
Context ∞ The impending Quantum Era poses both opportunities and significant challenges for the security of digital assets and blockchain networks, which currently rely on cryptographic primitives vulnerable to quantum attacks. The cybersecurity community is actively preparing for this shift by developing and standardizing post-quantum cryptography, designed to withstand quantum computational threats. Monitoring progress in quantum hardware development and cryptographic research is crucial for understanding the future resilience of digital systems.
