Part 5/11:
Despite the theoretical advantages, practical challenges abound. Qubits are extremely sensitive to environmental factors, making them prone to errors. This fragility limits the potential for scaling quantum technology. To solve complex problems, researchers estimate that up to 20 million qubits may be needed to break RSA encryption, a common standard for internet security, but currently, the largest machines barely have a fraction of that.
Additionally, claims about quantum computing’s revolutionary potential often lack real-world applications—making comparisons with classical computers misleading. Demonstrations of quantum algorithms tend to yield results that are statistically observable but lack practical relevance outside of academic or experimental contexts.
