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: The deterministic teleportation process succeeds with order unit probability for any input state, as it prepares maximally entangled two-qubit states as a resource and distinguish all Bell states in a single two- qubit measurement with high efficiency and high fidelity.

TL;DR: In this paper, the authors explore current engineering limitations and find a way to halve the measurement time for single-shot dispersive readout, without sacrificing fidelity, which may bring superconducting quantum technology even closer to the demanding thresholds of quantum computing.

TL;DR: In this article, the state-of-the-art readout of superconducting qubits is based on the dispersive interaction with a readout resonator and the authors demonstrate how the careful design of system parameters leads to fast and high-fidelity measurements without affecting qubit coherence.
