Key Features of Google’s Quantum Chip
Google’s latest quantum chip, Willow, represents a significant advancement in quantum computing technology. It has achieved several milestones that set it apart from competitors:
-
Error Correction Breakthrough: Willow has surpassed the Quantum Error Correction Threshold, which is crucial for scaling up quantum computers while maintaining performance and reliability
-
Performance Benchmark: In a recent test, Willow completed a task in five minutes that would take the fastest classical supercomputer approximately 1037 years to solve. This demonstrates its potential to outperform traditional computing methods significantly
-
Improved Coherence Time: The coherence time of Willow is nearly 100 microseconds, which is five times better than its predecessor, Sycamore. This improvement allows for more complex calculations to be performed accurately
