Briefings

A new open-source spin qubit control package named SpinQICK, built on Xilinx RFSoC, successfully demonstrated coherent control, state preparation, and readout for a fully connected triangular exchange-only quantum device. The study introduces a novel dynamical decoupling sequence specifically designed for this triangular geometry to characterize electrical noise. This work establishes SpinQICK as a low-cost, flexible platform for semiconductor spin qubit control and offers a pathway for hardware optimization through qubit-level noise diagnostics.

Key points

• SpinQICK is an open-source spin qubit-control package built on Xilinx RFSoC that enables precise time-domain voltage control and readout of semiconductor spin qubits.
• The study experimentally verified a novel dynamical decoupling sequence enabled by a fully connected triangular exchange-only device to characterize electrical noise.

Context

SpinQICK addresses the gap in affordable, flexible high-speed control electronics for semiconductor spin qubits by leveraging Xilinx RFSoC's high sampling-rate signal generation and advanced DSP capabilities.

Limitations

The evidence is a preprint (arXiv:2610.31998v1) from October 2026, and the specific experimental results regarding the novel dynamical decoupling sequence remain unverified as a published finding.
