Quantum Supremacy: What’s Next After Google's Milestone?
Introduction In 2019, Google announced that it had achieved a milestone in quantum computing known as "quantum supremacy." Their quantum processor, Sycamore, performed a complex computation in 200 seconds that would take the most powerful classical supercomputers thousands of years to complete. This breakthrough marked a significant moment in the history of quantum computing. But, what comes next? Let’s explore the future after Google's achievement and what lies ahead for the quantum revolution. A Quick Recap: What is Quantum Supremacy? Quantum supremacy refers to the point at which a quantum computer can perform a calculation that is practically impossible for classical computers. It doesn't mean quantum computers are immediately more useful for all tasks—it’s more of a proof-of-concept to show that quantum machines can outperform classical systems on specific problems. Google’s achievement was a landmark, but it was also narrow in scope. The task solved by Sycamor...
