One of the most promising applications of quantum computing is in medicine and materials science. Simulating molecules at the quantum level could lead to breakthroughs in drug discovery and the design of new materials. Another major field is cryptography, where quantum algorithms could potentially break widely used encryption methods, forcing a rethinking of digital security.

Despite the hype, quantum computing is still in its early stages. Qubits are extremely fragile and require near-absolute-zero temperatures to function. Current quantum machines are limited in scale and prone to errors. However, research is advancing rapidly, with tech giants and startups investing billions to build practical quantum devices.
