TL;DR: Deterministic quantum state transfer and entanglement generation is demonstrated between superconducting qubits on distant chips using single photons and has the potential to be used for quantum computing distributed across different nodes of a cryogenic network.

TL;DR: In this article, the authors present design criteria for qubit drive lines, flux lines, and output lines used in typical experiments with superconducting circuits and describe each type of line in detail.

TL;DR: This work experimentally demonstrates a reset scheme for a three-level transmon artificial atom coupled to a large bandwidth resonator that has no additional architectural requirements beyond those needed for fast and efficient single-shot readout of transmons, and does not require feedback.

TL;DR: In this paper, individual Purcell filters are used for each readout resonator to protect the qubits from untargeted readout signals, and from radiative decay, in order to achieve fast, high-fidelity readout of qubits.
