Multi-qubit readout and control for a qubit-based dark matter detector

Superconducting qubits are sensitive electromagnetic field probes that can be utilized to detect high energy cosmic and terrestrial background radiation. This radiation causes qubit decoherence and contributes to correlated errors in quantum computers. Studying this decoherence is essential to building a fault-tolerant quantum computer. Similarly, certain qubits can be excellent Dark Matter detectors due to their sensitivity to low-energy optical phonons which can be exploited to look for sub-eV scattering. Our goal is to control and readout multiple qubits array to develop Dark Matter and radiation detectors. In this talk, we demonstrate simultaneous control and readout of multiple qubits using the Quantum Instrumentation Control Kit (QICK) along with an in-house RF companion board to generate, read, and process microwave signals.
