History

Historical Context

Quantum computing has evolved significantly since the 1980s, with key milestones including Shor's algorithm in 1994 and the first commercial quantum computer by D-Wave in 2011. In 2019, Google claimed quantum supremacy with its Sycamore processor, completing a calculation in 200 seconds that would take classical computers 10,000 years. This achievement spurred investments from major tech companies, highlighting the transformative potential of quantum technologies.
