These discoveries transformed the perception of quantum computing from a scientific curiosity into a potential disruptor of global digital infrastructure. Trapped Ions Companies like IonQ emerged, focusing on the stability of individual atoms.
Quantum Computing Invention Timeline 1980s 1990s: Key Breakthroughs and Milestones
The invention became less about theory and more about engineering fragile quantum states into stable processors. Feynman’s Vision The most influential spark came from Richard Feynman in 1981, who argued that simulating quantum systems on classical computers was inherently inefficient.
While the specific task had no practical application, it was a pivotal engineering milestone, proving that quantum devices could outperform classical machines under controlled conditions. Approach Key Milestone Superconducting Qubits Google and NASA began working with D-Wave systems in the early 2010s.
