Quantum computing promises incredible power—but it’s also a threat to current encryption. Cybersecurity experts are racing to develop post-quantum cryptography. Companies like IBM and Google are testing quantum-safe algorithms. Governments are funding research to protect critical infrastructure. Financial institutions are especially vulnerable, given their reliance on secure transactions. Startups like PQShield are offering solutions to future-proof data. The transition won’t be easy—legacy systems need massive upgrades. Awareness is growing, but action is lagging. The quantum era demands a cybersecurity rethink—before it’s too late.
