Quantum computing is rapidly evolving, posing significant challenges to current cybersecurity frameworks. Its potential to disrupt encryption methods necessitates immediate attention from business leaders and legal professionals.
Understanding Quantum Computing
Traditional computers use bits (0s and 1s) to process information. In contrast, quantum computers utilize qubits, which can exist in multiple states simultaneously due to the principles of superposition and entanglement. This allows quantum computers to perform complex calculations at unprecedented speeds, potentially solving problems that are currently intractable for classical computers.
The Threat to Current Encryption Methods
Many of today’s encryption systems, such as RSA and ECC, rely on the computational difficulty of certain mathematical problems. Quantum algorithms, notably Shor’s algorithm, can efficiently solve these problems, rendering current encryption methods vulnerable once sufficiently powerful quantum computers are developed.

A pressing concern is the “harvest now, decrypt later” strategy, where adversaries collect encrypted data now with the intention of decrypting it in the future using quantum computers. (CSO Online)
