Digital Predistortion of Power Amplifiers for Quantum Computing
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter applies digital predistortion (DPD) to linearize the power amplifier in microwave quantum control signal generators. By compensating for nonlinearities and memory effects, DPD reduces the mean qubit gate infidelity by approximately one order of magnitude without reducing the output power.
