TL;DR: The generation and observation of coherent temporal oscillations between the macroscopic quantum states of a Josephson tunnel junction are reported by applying microwaves with frequencies close to the level separation.

TL;DR: The production and tomography of genuinely entangled Greenberger-Horne-Zeilinger states with up to ten qubits connecting to a bus resonator in a superconducting circuit are reported, demonstrating the largest entanglement created so far in solid-state architectures and paving the way to large-scale quantum computation.

TL;DR: In this article, a scheme to achieve maximally entangled states, controlled phase shift gate, and SWAP gate for two superconducting-quantum-interference-device (SQUID) qubits, by placing SQUIDs in a microwave cavity is presented.

TL;DR: A way to teleport multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network is presented, in such a way that the required auxiliary qubit resources, local operation, and classical communication are considerably reduced.

TL;DR: In this article, a superconducting quantum interference device (SQUID) flux qubit that is robust against fabrication variations in Josephson-junction critical currents and device inductance has been implemented.
