Engineers Develop Control Electronics for Quantum Computers That Improve Performance, Cut Costs

FermiLab, April 29, 2022

The Quantum Instrumentation Control Kit developed by engineers at the U.S. Department of Energy's Fermi National Accelerator Laboratory (FermiLab) and the University of Chicago can enhance quantum computer performance while reducing control/readout electronics' cost. The researchers created a field-programmable gate array (FPGA)-based controller for quantum computing experiments, and reduced the size of an equipment rack to that of a single electronics board that can interoperate with many types of superconducting quantum bits (qubits). The radio frequency (RF) board and FPGA controller can control eight qubits in their simplest iteration, and combining all RF elements in one board increases operational speed and precision, allowing real-time feedback and error correction. ...
