Google Develops Method for Continuous Calibration in Quantum Computing

Quantum computing faces several challenges, including the need for high-quality hardware qubits and the generation of states for universal computation. One specific challenge is the calibration of superconducting qubits, which can exhibit variations among individual units. Calibration involves testing different frequencies and amplitudes of microwave pulses to minimize error rates. Traditional calibration cannot occur during calculations, leading to drift issues in lengthy algorithms. Google has developed a method to perform calibration using data from error correction processes, potentially addressing this issue.
