Lawrence Berkeley Team Bounds Filter Errors for Qubit Control

Quantum ZeitgeistSeptember 23, 20264 min read

A functional fixed-point digital filter consuming just 88 DSP slices now corrects waveform distortions in superconducting qubits with only SI{162}{ns} of added latency. This detailed FPGA implementation bypasses reliance on unspecified commercial solutions previously hindering custom system development. Delivering accurate flux line calibration, this work represents practical progress towards fully calibrated quantum processors for open science platforms.

Correcting waveform distortion in superconducting quantum processors previously relied on commercial solutions lacking detailed implementation specifics. Functional digital filters now enable real-time correction using custom hardware, allowing precise control over data formats essential for open-source systems. The new system operates with a fabric clock rate of SI{500}{MHz}, consuming eighty-eight DSP slices and adding only SI{162}{ns} of latency to signals. Detailed digital filters correct signal distortions within superconducting quantum processors utilising custom hardware;…
