An investigation of USRP FPGA as a platform for quantum sensing and control

Abstract

This work develops a digital feedback control system for a quantum system in an effort to determine the viability of the Universal Software Radio Peripheral (USRP) 2954R for quantum sensing and control. Conducted alongside Lisa Poyneer and John Breneman at the Lawrence Livermore National Laboratory (LLNL), this work evaluates the radio frequency and signal processing capabilities of the USRP platform in relation to an array of other platforms, develops workflows for incorporating existing algorithms into the USRP environment and ensuring the portability of the algorithms to other Field Programmable Gated Array (FPGA) platforms. This work confirms the USRP as a viable platform for quantum sensing through experimentation on the quality of the radio frequency front end and USRP development environment. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. IM RELEASE NUMBER LLNL-TH-809963.
