Exchange-only qubit demonstrations using the spinQICK FPGA control platform
ORAL
Abstract
The spinQICK package [1], an open-source spin qubit, RFSoC-based control software built with the Quantum Instrumentation Control Kit (QICK) [2], and developed by HRL Laboratories, has previously shown coherent control of single Loss-DiVincenzo qubits. This talk will outline the expansion of spinQICK for exchange-only qubit control. This will include demonstrations of exchange calibration, characterization, and coherent operations on a triangular triple-quantum dot device [3]. Finally, we present experimental data collected with spinQICK comparing various dynamical decoupling sequences on this triangular dot geometry [4].
