What is cross-entropy benchmarking, and how is it used to evaluate the performance of quantum gates on the Sycamore processor?
Cross-entropy benchmarking (XEB) is a critical technique employed to evaluate the performance of quantum gates, particularly on quantum processors such as Google's Sycamore processor. This benchmarking method is instrumental in the field of quantum computing, where it serves as a robust tool to measure how well a quantum processor can perform complex quantum operations, which
What is quantum supremacy, and who coined the term?
Quantum supremacy is a term that signifies the point at which quantum computers can perform tasks that classical computers practically cannot, within a reasonable timeframe. This concept is pivotal in the field of quantum computing, as it marks a significant milestone demonstrating the potential of quantum machines to solve certain problems more efficiently than traditional
