Demonstrating Magic State Cultivation on the Willow Processor | Google Quantum AI

A magic state is a special, single-qubit state that allows a quantum computer to perform a T gate: an operation vital for universal quantum computation. Magic State Cultivation is a novel approach to creating reliable magic states without the overheads and bottlenecks associated with existing methods. In this video, Emma Rosenfeld from Google Quantum AI explains how she and her team tested magic state cultivation in practice on our Willow processor. By filtering noisy inputs for exceptionally pure states, the experiment delivered a 40x error reduction with 99.99% fidelity. She also details the benchmarking method for accurately measuring the quality of cultivated magic states.
