The race for quantum supremacy—where quantum computers outperform classical ones—has intensified in 2025, driven by breakthroughs from Google, Microsoft, Amazon, and others. With the global quantum computing market projected to hit $2.7 billion by 2030, these advancements signal a pivotal shift. This professional, reader-friendly news article explores why the race is heating up, key developments, and implications, crafted for tech enthusiasts and industry stakeholders. Key Breakthroughs Driving the Race 1. Google’s Willow Chip Achievement: In December 2024, Google’s Willow chip, with 105 superconducting qubits, solved a benchmark problem in 5 minutes—a task estimated to take supercomputers 10 septillion years. Why It Matters: Willow’s exponential error reduction as qubit count grows marks a historic leap, achieving “below threshold” performance since 1995....
