FPGA based control electronics for quantum applications with ultra-low latency

The long coherence time quantum systems, in the focus of the Superconducting Quantum Materials and Systems (SQMS) research center, require high resolution and dedicated electronics to measure and control the states of superconducting qubits coupled with record high photon lifetime cavities. Hardware acceleration using field programmable gate arrays (FPGAs) has a key role in the improvement of the speed and the efficiency of the quantum systems characterization and controls. Custom hardware design translates into robust controls and high-fidelity readouts, ultimately leading to the achievement of high performances and accurate results. We will present dedicated instrumentation to engineer quantum controls with ultra-low latency to enable future applications.
