TL;DR: Diamond spin qubits are established as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing through unconditional teleportation of arbitrary quantum states between diamondspin qubits separated by 3 meters.

TL;DR: Here, a time-resolved, continuous parity measurement of two superconducting qubits is performed using the cavity in a three-dimensional circuit quantum electrodynamics architecture and phase-sensitive parametric amplification to produce entanglement by parity measurement reaching 88 per cent fidelity to the closest Bell state.

TL;DR: By integrating recent developments in high-fidelity qubit readout and feedback control in circuit quantum electrodynamics, a state-of-the-art transmon is transformed into its own real-time charge-parity detector and it is demonstrated that quasiparticle tunnelling does not presently bottleneck transmon qubit coherence.

TL;DR: In this article, a three-node entanglement-based quantum network is presented, which combines remote quantum nodes based on diamond communication qubits into a scalable phase-stabilized architecture, supplemented with a robust memory qubit and local quantum logic.

TL;DR: In this paper, the active suppression of transmon qubit dephasing induced by dispersive measurement using parametric amplification and analog feedback was demonstrated using real-time processing of the homodyne record.
