QubiC update, the flexible full stack quantum bit control system

ORAL

Abstract

Superconducting qubits interact with the classical world through radio frequency pulse generation and detection. Quantum control systems generate these RF pulses to manipulate qubit states and also conduct RF probe and measurements to read out the qubits state. The QubiC is an open source quantum bit control system based on the software defined radio concept and utilizes advanced Field programmable gate array (FPGA) together with low noise analog front end modules. This system provides a full stack control solution from the hardware to the software API. This talk will update the recent developments of the QubiC system, including multiple FPGA platform support as well as new control features.
