Description

Superconducting quantum bits, or qubits, are among the most promising technologies for the realization of fully-functioning quantum computers, and their possible applications, ranging from quantum simulations to quantum sensing and particle detection, make these devices a potentially interesting tool also for particle physics experiments.
A fundamental step in the research on this field has been the development of a reliable technology for the manipulation and readout of qubit states. Over the past years, results on single-qubit measurements have improved dramatically, with experiments that reached readout fidelities exceeding 99.5% in some devices. Though, in order to unlock the full potential of quantum devices, the same results need to be achieved also in control and readout systems capable of simultaneously operating multiple qubits.
In this talk I will illustrate a system for the readout and control of superconducting qubits capable of probing simultaneously multiple qubits. The system relies on RFSoC boards for the production and the readout of the RF pulses used for the measurement and can probe simultaneously up to four qubits, with the possibility to scale to a higher number of qubits.
