Qubits are the main building blocks of quantum devices: improving their performance at every stage of development is thus crucial. A qubit’s properties such as its coherence time are directly affected by their architecture and design as well as by the materials chosen. Building a qubit to test each possible variable adds an unnecessary overhead to the characterization effort: this is why it is desirable to develop fast and efficient benchmarks at earlier stages in the process.
In this webinar, application scientists Ed, Jim, Jelena and Clemens will demonstrate how lock-in amplifiers operating at frequencies well below the qubits themselves offer a prime way to probe and understand material properties relevant for qubit coherence while keeping measurement times and complexity to a minimum. They will discuss the basic working principles of semi- and superconducting qubits and will show you how to characterize frequency and loss fluctuations in readout resonators.
