Quantum computing follows an exponential growth pattern called Rose's Law, where qubits double every 5 years compared to classical computing's 2-year cycle. This creates a double exponential growth that could theoretically achieve massive computational power by 2040. However, the main bottleneck is error rates in quantum systems, currently at 1% per operation, which require thousands of physical qubits to create one reliable logical qubit. Reducing error rates is the critical engineering challenge that will determine whether quantum computers can revolutionize fields like drug discovery, materials science, and cryptography.
